Translating Piano Pedagogy Into Biomechanical Language: A Qualitative Framework for Interdisciplinary Knowledge Exchange
Authors: Sabo Jeffrey , Comeau Gilles , Guptill Christine , Dvorkin Robert , Russell Donald
Published: February 2023

Pianists experience high rates of Playing-Related Musculoskeletal Disorders (PRMDs). Biomechanical factors have been investigated by both researchers and music teachers as potentially significant in PRMD development. Knowledge exchange between the fields of music and science about PRMDs may be beneficial, but differences in language use can make interdisciplinary communication challenging. One potential solution is to translate pedagogical ideas into language that is consistent with biomechanical science. Doing so could improve interdisciplinary communication and allow for scientific examination of pedagogical ideas. However, no methods for doing so have been published. To fill this gap, we developed a methodological framework with two stages for translating ideas about piano technique into scientific language: Stage 1 uses Qualitative Content Analysis to summarize pedagogical content; then, Stage 2 includes an “Analysis of Biomechanical Language,” in which researchers translate the ideas described in Stage 1. Both stages are collaborative and rely on expert consultation to produce an appropriate translation. This article outlines the framework and explains how it was used in an initial study on the Taubman Approach. Further methodological guidance to assist researchers in future studies is given based on some of the challenges encountered in the initial study. The framework and guidance here will allow researchers to carry out more studies of this kind. Because the framework is newly developed, it will likely need to be adapted further as more studies are done.

Published: February 2023

Background and objective

Polycystic ovary syndrome is one of the most common types of endocrine and metabolic diseases in women of reproductive age that needs to be screened early and assessed non-invasively. The objective of the current study was to develop prediction models for polycystic ovary syndrome based on data of tongue and pulse using machine learning techniques.

Methods

A dataset of 285 polycystic ovary syndrome patients and 201 healthy women were investigated to identify the significant tongue and pulse parameters for predicting polycystic ovary syndrome. In this study, feature selection was performed using least absolute shrinkage and selection operator regression. Several machine learning algorithms (multilayer perceptron classifier, eXtreme gradient boosting classifier, and support vector machine) were used to construct the classification models to predict the presence of polycystic ovary syndrome.

Results

TB-L, TB-a, TB-b, TC-L, TC-a, h3, and h4/h1 in tongue and pulse parameters were statistically associated with polycystic ovary syndrome presence. Among the several machine learning techniques, the support vector machine model was optimal for the comprehensive evaluation of this dataset and deduced the area under the receiver operating characteristic curve, DeLong test, calibration curve, and decision curve analysis.

Conclusion

The machine learning model with tongue and pulse factors can predict the existence of polycystic ovary syndrome precisely.
Open Bankart Repair
Authors: Rasyid Hermawan Nagar , Prasetia Renaldi
Published: February 2023

Shoulder instability is one of the most common complaints seen by orthopaedic surgeons taking care of an athletic patient. The management of shoulder instability has varied over the years and significant controversy and debate about the proper management of this pathology.

The surgical treatment of anterior shoulder instability can present a dilemma. Historically, an open Bankart repair was the benchmark solution. Over the last decade as surgeons became more arthroscopically safe, the pendulum swung and a paradigm shift occurred. However, more recent studies have challenged this trend and, subsequently, revived interest in open repair. Thus, we feel it is critical to provide a more contemporary stepwise description of a procedure that has become essentially abandoned. The goal is to provide tips and pearls to achieve optimal exposure and, ultimately, a robust repair for a notoriously challenging operation. Patient selection, risk factors, and pathology are crucialin makig the correct treatment decision. The benefits of open Bankart repair including the indication of open Bankart repair will be discussed. Additionally, a reliable surgical technique will be presented
ACL Reconstruction for Open Physes Patient
Authors: Utoyo Ghuna Arioharjo
Published: February 2023

Introduction:

Participation of young athletes contributes to increment of ACL tears cases in children and adolescence. Management of ACL tears in that age group remains debatable. Traditionally, patients with immature bone have been treated without surgery or delayed reconstructive surgery to prevent iatrogenic growth retardation due to epiphyseal injury. However, conservative management showed poor results, the patient subsequently developed recurrent knee instability leading to progressive intraarticular damage, including secondary meniscus and chondral injuries. Special reconstruction technique is required to maintain the growth plate. The purpose of this study is to point out reconstruction technique available on managing ACL rupture.

Method:

This presentation review does systematic evidence based on literature review of management of ACL injury in skeletal immature patient.

Results:

There are some techniques that can be performed for paediatric patients are physeal sparing, with iliotibial band reconstruction, ACL reconstruction with all-epiphyseal tunnels and post distal fixation, all-epiphyseal tunnels reconstruction and fixation, partial transphyseal technique, and trans-physeal technique. The surgical technique was determined based on maturity and bone age using Tanner staging and hand radiographs. In pre pubertal patients, Tanner stage 1 or 2 (boys 12 years and girls 11 years) was performed using a physeal sparing. Young adolescents are still in their infancy, Tanner stage 3 or 4, boys 13-16 years old, it is better to have ACL reconstruction done with partial transphyseal or transphyseal technique. Older adolescents with physeal closure (males 15 years and girls 14 years) ACL reconstruction were performed as in adult patients.

Discussion:

The choice of reconstruction technique in pediatric patients is based on the maturity and bone age of the child. In the pre-pubertal period with Tanner stage 1 or 2 experiments can be carried out non-operative measures followed by physeal sparing reconstruction, young adolescents are still in their infancy, transphyseal reconstruction is carried out, reconstruction in older adolescents is carried out as in adults. Some consideration makes decision whether not to operate or operate the patient. Concerns regarding injury to physic, leg length discrepancy, and source of graft led the innovation of the surgical technique to reconstruct the ACL.
Discoid Meniscus
Authors: Ifran Nadia
Published: February 2023

Discoid meniscus is an abnormal congenital variant of meniscus. The incidence is relatively low, but higher incidence was found in East-Asian population. Incidence of discoid lateral meniscus range from 0.4% to 17%, while discoid medial meniscus range from 0.06% to 0.3%. Moreover, recent studies in Asian population found high incidence of bilateral discoid meniscus up to 97%. Discoid meniscus not only has abnormal morphology and vascularity but also abnormal in structural arrangement of collagenous fiber. Hence, discoid meniscus has a higher risk of tear. There are many classifications from classic Watanabe to the more clinically relevant Anh’s classification. Sign and symptoms, physical examination and radiological findings will be discussed in this paper. The treatment of discoid meniscus range from observation to surgical treatment. The decision making is depending on symptoms and patient characteristic. Algorithm of treatment will be proposed in this paper.

Authors: Giarso Peter
Published: February 2023

Introduction:

In some rural hospitals with limited resources, most meniscal tears are often untreated. A simple, low-cost option for meniscal repair or partial meniscectomy has been developed as an alternative with good results.

Methods:

We explain some techniques for meniscus tear treatment based on literature reviews and expert experiences. The techniques include with or without an arthroscopy setting, with or without a meniscus device, and limited supporting infrastructure such as MRI.

Conclusion:

Meniscus tear can be managed adequately in limited resources setting with some conditions. Good diagnosis and evaluation are important before deciding on the technique.
Understanding Lateral Ankle Instability
Authors: Pitarini Astuti
Published: February 2023

Lateral ankle sprain is one of the most common sports injuries both in high level and recreational athletes. The frequency of injuries increases in recent years as more sports participations grow. Untreated ankle sprain can lead to deteriorated chronic ankle instability, thus understanding the management is of most important.

Surgery for ankle instability can varied from a simple non augmented repair, augmented repair using autograft/allograft/or other choices of internal bracing, and revision cases of failed primary repair. The decision of what surgery is of the surgeon learning curves. However, with a proper diagnosis, a simple non augmented repair is acceptable with high success rate. In certain population and narrow indication, surgeon need other armamentarium such as augmented reconstruction using graft or other technique to avoid failure of primary case that leads to revision.

At last, the success of lateral ankle instability surgery is highly dependent on proper phases of rehabilitation period. Understanding all matter that involves in the recovery of ankle ligament repair is of most important for the best outcome of the patients.
Implantless MPFL Reconstruction
Authors: Pontoh Ludwig Andre
Published: February 2023

The medial patellofemoral ligament (MPFL) acts as primary restraint to lateral patellar dislocation and its rupture has been reported in almost all cases of acute patellar dislocation. Various surgical techniques have been described for MPFL reconstruction, using many femoral and patellar fixation techniques and different grafts.

The described method of MPFL reconstruction would avoid any implants. The technique does not use any implants and could be considered when there are limited resources or economic constraints
High tibial osteotomy with ACL reconstruction
Authors: Winata Fahroni Cahyono
Published: February 2023

Knee malalignment in coronal and sagittal can alter knee biomechanics especially in anterior cruciate ligament (ACL) deficient knee that easily underdiagnosed and can endangered the reconstructed ACL to failure.

Varus deformity is one of the coronal knee malalignment that shown increased tension on ACL and contribute to medial compartment degeneration.

Sagittal malalignment also shown related effects on native ACL and reconstructed one. Increased posterior tibial slope will increase anterior tibia translation in weight-bearing and increase stress received by the reconstructed ACL. Eventually will leads to failure of the reconstructed ACL.

High tibial osteotomy (HTO) can be utilized for deformity correction to create more biomechanically stable knee. ACL reconstruction can be performed simultaneously with HTO to achieve better outcomes and reduce re-tear rate of the reconstructed ACL.
Primary ACL Repair
Authors: Hasan Jafri
Published: February 2023

The anterior cruciate ligament (ACL) is a ligament in the center of the knee that functions as an important knee stabilizer. It is one of the most injured ligaments in the knee. ACL injuries occur approximately 70% of the time without any form of physical contact. The majority of the time, they happen during pivoting motions, poor landings, or sudden acceleration or deceleration. Although reconstruction is largely acknowledged as the gold standard treatment option for ACL injuries, many patients continue to have problems, including graft failure, inability to return to sporting activities, and the development of arthritis. More than a century ago, primary ACL repair was documented, but due to the state of research at the time and perceived disappointing results, it was abandoned. During the last decade, there has been a renewed interest in preserving ACL in order to avoid some of the consequences associated with its reconstruction. Promising results in a clearly defined subset of patients have been documented in recent trials. Repair of the ligament has potential advantages over reconstruction of the ligament, such as decreased surgical morbidity, faster return of range of motion, and minimally invasive surgery. This presentation will focus on primary ACL repair, assess the indications, and describe the techniques.
Correlation between Leg Length Discrepancies (LLD) with ITB Syndrome: A Systematic Review
Authors: Nurfadhilah Muhammad Iqbal , Yudhistira Jaka Fitria
Published: February 2023

Backgrounds:

Iliotibial band syndrome (ITBS) is one of the many different causes of lateral knee pain. The iliotibial band (ITB) is the distal fascial continuation of the tensor fascia lata, gluteus medius, and gluteal maximus. It traverses superficial to the vastus lateralis and inserts on the Gerdy tubercle of the lateral tibial plateau and partially to the supracondylar ridge of the lateral femur. The etiology of ITBS is controversial and likely multifactorial. One theory advocates that repetitive friction of the ITB and the lateral epicondyle during flexion and extension lead to inflammation of the contact area of the ITB. The discrepancy in leg length has long been a source of controversy in the research and clinical environment. It disagrees on many aspects, such as its effect on various neuro musculoskeletal disorders and the evaluation of different measurement methods. Several orthopaedic disorders have also been associated with LLD, including low back pain, iliotibial band syndrome, hip osteoarthritis, intervertebral disc disease, and stress fractures of the femur, tibia, fibula, and metatarsal bones.

Methods:

Our trial was an international, expertise-based, randomized, controlled trial. Details of the trial objectives and design have been published previously. To identify studies about correlation between leg length discrepancy with ITB Syndrome, we reviewed the Cochrane, Pubmed, Embase databases for relevant articles published up to June 2022. Following the PICOS (Participants, Interventions, Comparisons, Outcomes and Study design) principle, the key search terms included (P) patients with ITB syndrome; (I) Leg length discrepancy; (C/O) the comparisons between ITB syndrome with leg length discrepancy thant without leg length discrepancy; (S) RCT, cohort study, or case-control study.

Results:

This study results Literature search through The flow diagram of study selection that shown in Figure 1. A total of RCT, cohort and case control study, meta analysis and systematic review about correlation between leg length dicrepancy with ITB Syndrome.Discussions: There can be a predisposition to developing IT band syndrome. Anatomy issues may include leg length discrepancy, an abnormal tilt to the pelvis, or bowed legs (genu varum). These situations can cause the IT band to become excessively tight, leading to increased friction and irritation as the band crosses over the femoral condyle with movement. leg length discrepancy, which can also increase ITB tightness. Leg length discrepancy can make an impact to biomechanical abnormalities. ITBS is usually caused by biomechanical abnormalities, often combined with overtraining.

Conclusions:

This confirms that may be leg length discrepancy also a factor that contributes to iliotibial band syndrome (ITBS).
Return to Activities after Arthroscopic Rotator Cuff Repair: A Systematic Review and Meta-analysis
Authors: Kholinne Erica , Marsetio Aldo Fransiskus , Singjie Leonard Christianto , Jeon In-Ho
Published: February 2023

Introduction:

Rotator cuff tear is one of the most common disorders in orthopedic surgery. When conservative treatment fails, arthroscopic rotator cuff repair has become the most common procedure to achieve a functional shoulder.

Objectives:

The articles on return to activities following arthroscopic rotator cuff repair have not been collectively analyzed and investigated. We aimed to review systematically and perform a meta-analysis of studies on the return to activities which consist of the return to work, return to sports, and return to daily activities following arthroscopic rotator cuff repair.

Methods:

Articles regarding return-to-activities were systematically searched using databases of PubMed, MEDLINE via EBSCO, ScienceDirect, and ProQuest. The review was done according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guideline. The study protocol was registered in the PROSPERO International Prospective Register of Systematic Reviews [ID: CRD42022318293]. Studies with a level of evidence 1-4 that examined the rate of return to activities after arthroscopic rotator cuff repair were included and analyzed.

Results:

Fifteen studies published between 2005 and 2021 were included, with 1065 patients. The patient populations are workers and athletes. The meta-analysis on the combined effect of a return to activities using the random-effects model was 88.5% (83.8% on return to work, 88.2% on return to sport, and 97.3% on return to daily activities). The mean duration for return to activities is 6.59 months. The return to activities is positively influenced by the female population, heavy workers, longer duration of symptoms, surgery in the dominant arm, and massive tear may have negatively affected the ability to RTA.

Conclusion:

As much as 88.5% of patients were able to return to activities after arthroscopic rotator cuff repair with a mean duration of 6.59 months. Preoperative factors may contribute to the rate and duration of return to sports. Clinical Relevance: Clinicians can educate the patients regarding the rate, duration, and factors that contribute to return to activities (return to work, sport, and daily activities) after arthroscopic surgery rotator cuff repair.
Functional Outcomes of ACL Reconstruction with Lateral Extra-articular Tenodesis Using Modified Lemaire Procedure Versus Modified MacIntosh Procedure: A Systematic Review
Authors: Laksana I Komang Mahendra , Aryana IGN Wien , Pratistha Indra Rukmana Tri
Published: February 2023

Introduction:

There is a wide variety of operating procedures for the treatment of ACL rupture with a variety of different functional outcomes. The purpose of this study was to systematically review the functional outcomes between two lateral extraarticular tenodesis (LET) procedures compared to Anterior Cruciate Ligament Reconstruction (ACLR) alone in studies with high levels of evidence. Two LET procedure was Modified Lemaire procedure and MacIntosh modified by Cocker-Arnold procedure.

Methods:

We performed a literature search for clinical studies comparing the two LET as an augmentation to ACL reconstruction with ACL reconstruction alone. The primary outcomes were the International Knee Documentation Committee (IKDC) score, the Lysholm score, and graft failures. We filtered all literature use inclusion and exclusion criteria to get the best quality literature that match with purpose of this study.

Result:

A systematic literature search was conducted online in July 2022. A total of 123 records were excluded, based on abstract and title screening. This selection process resulted in the final 6 articles for inclusion in the systematic review. The best functional outcomes were obtained from the ACL reconstruction procedure with the addition of the LET procedure, whereas between the two LET procedures did not give different results.

Conclusion:

ACL reconstruction with the addition of the LET procedure can maintain better rotational stability so as to reduce the incidence of graft failure and will provide better functional results compared to ACL reconstruction alone. However, the two LET procedures do not show different functional outcomes because they have the same role, which is to increase the rotational stability of the knee joint.

Authors: Rawung Rangga Bayu Valentino , Lubis Andri Maruli Tua , Reksoprodjo Adisa Yusuf , Baghi Raynald
Published: February 2023

Introduction:

Reconstruction of Anterior Cruciate Ligament (RACL) is a procedure to restore stability to the knee thereby protecting against the risk of damage to the meniscus and cartilage that can lead to early knee osteoarthritis. There are three popular autografts in RACL, namely Bone patellar tendon bone (BPTB), Hamstring tendon (HT), and Quadriceps tendon (QT). BPTB is the first choice in RACL, especially for professional athletes and high demand patient, while in Asian populations, HT is the most popular RACL. In Indonesia, Quadriceps tendon is less popular graft, but the use of the quadriceps tendon autograft (QTA) for RACL has received increased attention in recent times. The purpose of this review is to impart knowledge that QT actually is a suitable graft with some advantages for RACL procedure

Method:

This is a review article using relevant literature collected from literature searches in PubMed, reference lists in existing reviews and papers, and conference presentations on the main topic of Quadriceps Tendon Autograft and Cruciate Ligament Reconstruction. We present profile of the graft, Patient Reported Outcome, Clinical Outcome, and complication

Results:

we found there are similar functional results between QT and BPTB and HT in regard of post ACL stability, Range of motion, Patient Reported Outcome Measures, flexion and extension strength, graft rupture, and donor site morbidity. QT also is a versatile graft, providing many options for operators

Conclusion:

QT should be a good alternative graft for RACL in Indonesia

Published: February 2023

Sport-related musculoskeletal injuries are a common health issue that can result in a reduction in performance. Tennis players, like many other sports players at recreational, collegiate, or professional levels, can experience injuries throughout the entire body. This study aimed to review the literature between 2017-2022 regarding many injuries experienced by tennis players. Original and review articles were searched through Scopus, MEDLINE via PubMed, and the Web of Science using key terms: tennis, injury, prevention, and risk factors. The researchers included systematic, experimental, observational, and qualitative studies that addressed tennis players, both professional and non-professional, in this review. From a total of 910 references searched through the descriptors, 301 references were included after reading the title and 283 were excluded after reading the abstract and full text. There were five articles that met the criteria for inclusion in the analysis. From those references, various injuries were obtained, and there was no injury that was the most frequent among them. The injuries mentioned include lumbar spine injury, shoulder injury, trunk injury, lower limb injury, upper limb injury, and muscle/tendon injury. The evolution of refined racket manufacturing technology, the age of players, and court surface composition can all have an impact on injury patterns. The information in this study contributes to trainers, researchers, and coaches who want to develop a prevention program to lower the number of incidents in this sport.

Authors: Subawa I Wayan , Pramana I Gusti Ngurah Bagus Andika , Pratama I Putu Agung Arya
Published: February 2023

Talus fractures are rare injuries to the hindfoot that still challenging in treatment. The anastomotic ring is likely to be damaged in neck talus fractures, which disrupt the blood flow and cause significant problems affecting fracture healing. Poor fracture healing and an increased risk of surgical complications were also associated with complex diabetes mellitus. We follow the progress of the illness from a 47 year old female complaint pain on her left ankle after falling down 6 months before outpatient. Physical examination shows swelling and varus deformed on affected ankle. Ankle x-ray and CT scan were done. Patient diagnosed as neglected close fracture left neck talus Hawkins type IV with type 2 diabetes mellitus. Then patient undergo an ankle arthroscopy to evaluate ankle joint and preserving ankle joint procedure by subtalar arthrodesis and iliac bone graft. This procedure achieved an excellent result in preserve ankle aligment, stability and soft tissue management. After 2 weeks wound heals without signs of infection and 3 weeks of followup VAS score mention from 0 to 1, with good compliance of the patient. Arthroscopy is safe procedure obtaining anatomical joint surface and reduce tissue damage. While arthrodesis enhance blood supply to encourage bone union, though loss of its ankle motion also has significant effect on ambulation.
Neglected Patellar Fracture Treated Using Ipsilateral Hamstring Autograft Augmentation: A Case Report
Authors: Indrayanti Putu Mira , Lubis Andri Maruli Tua
Published: February 2023

Introduction:

Inferior pole patellar fractures occur in relatively young patients after eccentric contraction of the quadriceps or direct trauma. Early diagnosis and adequate treatment lead to excellent outcomes and prevent tendon retraction and scarring. The aim of surgical treatment is to restore of extensor mechanism rather than anatomical articular reduction. We propose a cerclage wire technique using ipsilateral hamstring augmentation for the patellar tracking restoration.

Case Description:

A forty nine-year-old female, presented to our sport clinic with chief complaint of pain in the left knee and difficulty in walking and standing in long period of time following a direct trauma falling from the stairs to the knee one year back. Clinical examination revealed gap in the left knee cap and the patient could not able to straighten the knee actively. Plain radiographs of knee were taken in anteroposterior and lateral views show fracture of the inferior pole of the left patella. Magnetic resonance imaging (MRI) of the knee confirmed inferior pole patellar fracture with the proximal migration of patella with no other intraarticular injuries with partial tear of left patellar tendon. Patellar tendon reconstruction was planned using ipsilateral semitendinosus (ST) and Gracillis (G) autograft and ORIF cerclage wire augmentation. Follow-up was performed after one month post-operation. Patient was able to straighten the left knee and fully weight bearing mobilized without any pain. Range of motion was 0/100 compared to the contralateral knee. Muscle atrophy was not found. Xray was performed and shows callus formation with stable fixation.

Conclusion:

Neglected patellar fracture is a rare occurrence, the treatment of which is a difficult challenge for orthopaedic surgeons. Therefore, the goal of surgical treatment of inferior pole fractures is restoration of extensor mechanism rather than anatomical articular reduction. In inferior pole fracture of the patella, comminution in fractured distal fragment is common and secure fixation to allow early motion is difficult to achieve. The advantage of the described technique is the possibility of immediate weightbearing and early mobilization. A parallel could be drawn with the biological augment for patellar tendon repair, in which semitendinosus augmentation allows immediate postoperative mobilization with excellent functional results. This allows patients with early functional exercise and has a positive significance for the smooth recovery of the articular surface of the patella and recovery of knee extensor device function. Functional impairment of the extensor mechanism and postoperative complications triggers the quest for finding the ideal technique.

Authors: Aryana I Gusti Ngurah Wien , Pramana I Gusti Ngurah Bagus Andhika , Prayudi Ida Bagus Deny , Dwipayana Anak Agung Krisna , Kristian Adiet Wahyu
Published: February 2023

Introduction:

Anterior Cruciate Ligament (ACL) injury is one of the most common knee injuries. ACL reconstruction is the current gold standard to restore functional of the knee. Graft selection is important for satisfactory outcomes. Currently, most used autograft are hamstring tendon (HT) and bone patellar tendon bone (BPTB) grafts. This study aims to thoroughly evaluate and review an alternative autograft for ACL reconstruction, which is peroneus longus tendon (PLT).

Method:

Systematic review and meta-analysis was conducted using PRISMA guidelines. Literature was searched through PubMed, Google Scholar, Science Direct and Cochrane Library using Boolean operators. This study included original articles reporting on (1) clinical studies of ACL reconstruction (single-bundle or double-bundle) using PLT autograft (anterior-half, posterior half, or full-thickness); and (2) studies directly comparing outcomes of PLT versus HT. All procedures were primary ligament reconstructions performed for symptomatic acute or chronic ACL injury, with or without meniscal injury. The outcomes assessed included clinical and functional outcome, namely IKDC score, AOFAS scale and FADI.

Results:

From 247 studies obtained, after full-text review, 4 studies met all eligibility criteria. A total of 259 patients were included in this study. No significant differences was found in IKDC score (p = 0.99) and FADI score (p = 0.11) but significant differences was found in the mean of AOFAS score in favor of HT autograft (p = 0.03).

Conclusion:

PLT autograft is a suitable alternative graft choice from the others for the knee of patients undergoing ACL reconstruction.

Authors: Siregar Eryanda Aulia
Published: February 2023

Introduction:

Instability of the proximal tibiofibular joint is a rare condition and may present with an atypical presentation due to its location and symptoms. Recent techniques and graft has allowed to repair tibiofibular joint. Iliotibial band autograft might be used as a choice for this case as its characteristic, cost effectiveness, minimal invasive graft harvesting procedure, and long term outcome bring consideration to use as choice for the treatment.

Objective:

To introduce the new technique for PTFJ instability by using ITB graft Case report: A 21-year-old office worker male came to our clinic with discomfort on lateral aspect of right knee. He injured his right knee after he externally twist his right knee when he was going to wake up (stand up) from bed. He experienced immediate lateral pain and swelling lateral knee pain persisted until 1 week before admitted to the hospital.

Discussion:

In our case, patient is a office worker without an adequate energy cause the joint becoming sublux. For the surgical technique , we took the graft form the center side of ITB with the intentional purpose of preventing Kaplan Fiber. For the reaming procedure we took place directly behind the fibula and keep the posterior capsule intact to prevent further damage and infection on surgical site. We choose to use biomaterial implant for this study because the use of biomaterial screw itself has a low complication rate compare to metallic screw with no significant different in outcome (6). This technique overall has a satisfaction result with improvement of Lyshom score

Conclusion:

Iliotibial band is an alternative graft that can be used for reconstruction in tibiofibular joint. For its minimal invasive technique and cost effectiveness and satisfy long term outcome coud be a consideration for the treatment in tibiofibular instability.

Button Position Following ACL Reconstruction in Hasan Sadikin Hospital Bandung
Authors: Telaumbana Tri Taufiqurachman , Utoyo Ghuna Arioharjo
Published: February 2023

Background:

Anterior cruciate ligament (ACL) reconstruction are done to restore function and preventing secondary osteoarthritis. The use of button has been popular as a method of femoral fixation during ACL reconstruction (ACLR) due to its securely easy and rapid application. The aim of this study was to review correct placement of tunnels for ACLR based on button position from radiographic examination at Hasan Sadikin Hospital Bandung.

Methods:

From July 2021 to August 2022 consecutive patients undergoing ACLR with single-bundle techniques were enrolled. Follow up were also done year after ACLR, patients underwent radiographic examination after surgery and clinical examination with International Knee Documentation Committee (IKDC) score.

Results:

There were 27 patients (3 women, 24 men) with mean age of 26.8 years (17 - 59). The angle measured between a line drawn along the femur diaphysis and the button position from anteroposterior x-ray was approximately 42.3o. In lateral view, 13 had shallow and high button placement, 4 had deep and high button placement and 10 had deep and low button placement (optimal). The optimal button placement for deep-shallow direction has a ratio of 42 to 80% (mean 61,14%) and for the high-low direction has ratio of 9 to 41% (mean 24,07%). In this study, all patients with optimal and non optimal position of laterally measured antero-posterior (AP) proximal-distal (PD) angle had increased IKDC (mean score 58.1 to 84.68).

Discussion:

X-ray, CT, fluoroscopy and direct endoscopic visualisation had been proposed for tunnel evaluation. This study used standard x-ray due to limitations from Badan Penyelenggara Jaminan Sosial-Kesehatan (BPJS) insurance. Button position should be across the tunnel opening with angle measured towards femur diaphysis to be around 39° in AP view. Lateral view should show optimal placement as mean ratio of 27% in the deep-shallow direction and 34% in the high low direction. IKDC was used as an outcome-measuring tool due to its comprehensive and complex questions.

Conclusion:

Correct button position for ACLR is important for the clinical outcome of the patients. This study shows that radiographic findings and patient’s clinical outcome is relevant to the quality of operative tunnel placement. A record of this finding is important for completeness of the radiological report. Button position from radiographic examination is usefull to evaluate correct placement of tunel for ACL reconstruction.

Published: February 2023

Background:

Tuberculous spondylitis is the classic presentation of extrapulmonary tuberculosis (TB). Bone and joint TB occurs in 5-10% of the population. Surgical procedures are performed to prevent worsening of neurological deficits, maintain vertebral stability, and early mobilization. The purpose of this study was to determine the characteristics of tuberculous spondylitis patients who underwent decompression and posterior Stabilization surgery at Hasan Sadikin Hospital, Bandung for the 2019-2021 period.

Method:

This study uses a descriptive design with a cross-sectional approach obtained from medical records at Hasan Sadikin Hospital in Bandung for the 2019-2021 period, the study uses total sampling. The inclusion criteria in this study were cases of tuberculous spondylitis who underwent decompression and posterior stabilization surgery. The exclusion criteria in this study were TB spondylitis patients who have not experienced bone destruction and respond to therapy. The data was then processed using Microsoft Excel and the 25th edition of SPSS and then presented as research results.

Results:

There were 68 subjects in this study consisting of 28 men and 40 women, aged 11–73 years with a mean age of 35 years. In this study, the chief complaint was back pain in 85% of cases, spinal deformity 54% of cases, and neurological deficits in 36% of cases. Most tubercular lesions occurred in the thoracic (53%), lumbar (45%), cervical (1%). The study also found that 16% had diabetes mellitus, 11% had heart disease, , 10% had hypertension. 82% of study subjects stated a decrease in pain as assessed using VAS.

Conclusion:

Characteristics of tuberculous spondylitis patients who underwent decompressive and posterior stabilization surgery at Hasan Sadikin Hospital for the period 2019-2021 mostly occurred at women with the age of 11-73 years, with dominan complaints in the form of back pain (85%), and then spinal deformity, and paralysis, and findings of tubercular lesions Mostly in the thorax (53%), and then lumbar, and cervical, and there was a decrease in the value of the VAS after decompression and posterior stabilization surgery at Hasan Sadikin Hospital.s
PCL Reconstruction Surgery in Third Grade PCL Rupture: A Case Series
Authors: Albar Husnul Fuad , Yudhadibrata Permana , Sitohang Robby Oscar
Published: February 2023

Objective:

The PCL is the largest and strongest intraarticular ligament of the knee joint, comprising of 2 functional bundles: the larger anterolateral bundle (ALB) and the smaller posteromedial bundle (PMB). Posterior cruciate ligament (PCL) tears comprise 3% of outpatient knee injuries. The treatment of complete, isolated PCL tears remains controversial. Some studies have reported good outcomes after conservative treatment of partial PCL tears, while others have reported poor results at long-term follow-up with disabling symptoms and functional limitations. This case series reported the first experience of PCL reconstruction in our institution and its associated outcome.

Methods:

This prospective case series was conducted from January to December 2021. Two patients were included in this case series. All the patients were diagnosed with PCL tear by an Orthopaedic surgeon. clinical examination, knee radiograph, and MRI were obtained in both patients. All patients underwent arthroscopic PCL reconstruction by a single senior Orthopaedic surgeon. Physical therapy was performed after the surgery. Clinical evaluation was followed up for 9 months. The outcome in this case series was the posterior drawer test and range of motion.

Result:

Two patients were included in this case series. A favorable outcomes were noted following PCL reconstruction surgery. There were negative posterior drawer test, posterior sag sign, and full range of motion in both patients.

Conclusion:

A PCL reconstruction surgery provided a satisfactory clinical outcome in terms of posterior drawer test, posterior sag sign, and range of motion. PCL reconstruction surgery is recommended in patients who present with grade 3 PCL injury.
Association of COVID-19 Lockdown With Increased Rate of Cyclops Syndrome in Patients With Unexpected Home-Based Self-Guided Rehabilitation After ACL Reconstruction

Published: February 2023

Background:

The risk of cyclops syndrome increases significantly after anterior cruciate ligament (ACL) reconstruction (ACLR) if complete extension is not recovered before the sixth postoperative week. The lockdown in France due to the COVID-19 pandemic led to an absence of supervised rehabilitation, requiring unexpected self-rehabilitation in patients who underwent ACLR just before lockdown.

Purpose:

To determine the rate of cyclops syndrome after ACLR in patients who underwent self-rehabilitation during lockdown.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A total of 75 patients receiving a hamstring graft for ACLR during the COVID-19 pandemic between February 10, 2022, and March 16, 2020, carried out self-rehabilitation during part of their first 6 postoperative weeks using exercise videos on a dedicated website. Clinical examination was performed at a minimum 1-year follow-up with International Knee Documentation Committee (IKDC), Lysholm, Tegner, and ACL–Return to Sport after Injury (ACL-RSI) scores. This group was compared with a matched-pair control group of 72 patients who underwent surgery in 2019 and completed postoperative supervised rehabilitation with a physical therapist. Rates and reasons for second surgery (arthrolysis, meniscal procedure) were also recorded.

Results:

In the COVID group (n = 72; 3 patients were lost to follow-up), the mean follow-up was 14.5 ± 2.1 months (range, 13-21) and rate of reoperation for clinical cyclops syndrome was 11.1% (n = 8). The rate of cyclops syndrome was significantly lower (1.4%) in the control group ( P = .01). In the COVID group, 8 patients underwent anterior arthrolysis at a mean of 8.6 months after the primary surgery, and 4 patients underwent another surgical intervention (meniscal procedure [n = 3], device removal [n = 1]). In the COVID group, mean Lysholm was 86.6 ± 14.1 (range, 38-100), Tegner was 5.6 ± 2.3 (range, 1-10), subjective IKDC was 80.3 ± 14.7 (range, 32-100) and ACL-RSI score was 77.3 ± 19.7 (range, 33-100).

Conclusion:

The rate of cyclops syndrome after ACLR was significantly greater in the COVID group versus the matched controls. The dedicated website was not effective at supporting self-guided rehabilitation and could benefit from interactive improvements so it is at least as effective as supervised rehabilitation.
The Populus alba cationic cell-wall-bound peroxidase (CWPO-C) regulates plant growth, lignin content and composition in poplar

Cationic cell-wall-bound peroxidase (CWPO-C) from Populus alba is the only Class III peroxidase that has been shown to be able to oxidize high molecular weight lignin polymers from sinapyl alcohol and previously, has been believed to be a lignin polymerization-specific peroxidase. However, using an Arabidopsis heterologous expression system, we showed recently that CWPO-C contributes to differentiation or early growth and is involved in auxin catabolism. In this study, to clarify the function of CWPO-C in poplar, we analyzed CWPO-C gene expression and phenotypic changes with CWPO-C overexpression and suppression. Real-time PCR and monitoring promoter activity of CWPO-C using β-glucuronidase (GUS) assay revealed that CWPO-C was strongly expressed in immature tissues, such as the upper stem, axillary buds, and young leaves, in addition to expression in developing xylem. In transgenic poplars in which the expression of CWPO-C was upregulated or suppressed, changes in stem growth, gravitropism bending time, lignin content and syringyl/guaiacyl (S/G) composition were observed. Overexpressing CWPO-C enhanced stem growth and gravitropic response (shorter bending time). With suppressed CWPO-C expression, the lignin content was reduced approximately 45% and the S/G ratio decreased by half. These results strongly suggest that CWPO-C plays a role in differentiation and early growth, as well as in lignin polymerization.
Traces of Introgression from cAus into Tropical Japonica Observed in African Upland Rice Varieties

Published: February 2023

Background

Asian rice Oryza sativa, first domesticated in East Asia, has considerable success in African fields. When and where this introduction occurred is unclear. Rice varieties of Asian origin may have evolved locally during and after migration to Africa, resulting in unique adaptations, particularly in relation to upland cultivation as frequently practiced in Africa.

Methods

We investigated the genetic differentiation between Asian and African varieties using the 3000 Rice Genomes SNP dataset. African upland cultivars were first characterized using principal component analysis among 292 tropical Japonica accessions from Africa and Asia. The particularities of African accessions were then explored using two inference techniques, PCA-KDE for supervised classification and chromosome painting, and ELAI for individual allelic dosage monitoring.

Key Results

Ambiguities of local differentiation between Japonica and other groups pointed at genomic segments that potentially resulted from genetic exchange. Those specific to West African upland accessions were concentrated on chromosome 6 and featured several cAus introgression signals, including a large one between 17.9 and 21.7 Mb. We found iHS statistics in support of positive selection in this region and we provide a list of candidate genes enriched in GO terms that have regulatory functions involved in stress responses that could have facilitated adaptation to harsh upland growing conditions.
