Passive ligament stability in natural knee: a cadaveric biomechanical study
Authors: Paszicsnyek Thomas , Bori Edoardo , Innocenti Bernardo 
Published: September 2020

Objectives:	Applying the correct amount of collateral ligaments tension in the knees during surgery is a prerequisite to restore normal kinematics after TKA. It is well known that a low value of ligament tension could lead to an instable joint while a higher tension could induce over-tensioning and problems at later follow-up. In this study, an experimental cadaveric activity was performed to measure the minimum tension required to achieve stability in the knee joint.Methods:	10 cadaveric knee specimens were investigated in this study. The femur and tibia were fixed with polyurethane foam in specific designed fixtures and clamped to a loading frame.Increasing displacement was applied to the femoral clamp and the relative force was measured by a loading-frame machine up to the stability of the joint, determined by a decrease in the derivate of the force/displacement trend followed by a plateau.The force span between the slack region and the plateau was considered as the tension required to stabilize the joint.This methodology was applied for joints with intact cruciate ligaments, after ACL resection and after further PCL resection, to simulate the knee behavior prior a CR and a PS implant.The test was performed at 0, 30, 60 and 90° of flexion. Each configuration was analyzed three times for the sake of repeatability.Results and Conclusion:	Results demonstrated that an overall tension of 41.2N (range 30.0-48.0 N) is sufficient to reach stability in a native knee with intact cruciate ligaments. Similar values appear to be sufficient also in an ACL resected knee (average 45.6, range 41.2-50.0 N), while higher tension is required (average 58.6N, range 40.0-77.0 N) were necessary in the case of PCL retention. Moreover, in this configuration, the tension required for stabilization was slighter higher at 30 and 60° of flexion compared to the one required at 0 and 90° of flexion.The results are in agreement to the ones found by other recent experimental study [Manning et al 2018 (KSSTA)] and shown that the tension necessary to stabilize a knee joint in different ligament conditions is way lower than the ones usually applied via tensioners nowadays.To reach functional stability, surgeons need to consider such results intraoperatively to avoid laxity, mid-flexion instability or ligament over-tension.

Published: September 2020

Total knee arthroplasty (TKA) is a common procedure that has become the standard of treatment for severe cases of knee osteoarthritis. Biomechanics and quality of movement similar to healthy were found to improve patient-reported outcomes.In this study, an evaluated musculoskeletal model predicted ligament, contact and muscle forces together with secondary tibiofemoral kinematics. An artificial neural network applied to the musculoskeletal model searched for the optimal implant position in a given range that will minimize the root-mean-square-error (RMSE) between post- TKA and native experimental tibiofemoral kinematics during a squat.We found that, using a cruciate-retaining implant, native kinematics could be accurately reproduced (average RMSE 1.47 mm (± 0.89 mm) for translations and 2.89° (± 2.83°) for rotations between native and optimal TKA alignment). The required implant positions changes maximally 2.96 mm and 2.40o. This suggests that when using pre- operative planning, off-the-shelf CR implants allow for reproducing native knee kinematics post-operatively.
A Novel Computer-Assisted Workflow for Treatment of Osteochondral Lesions in the Knee

Published: September 2020

Computer-Assisted Orthopaedic Surgery (CAOS) is now becoming more prevalent, especially in knee arthroplasty. CAOS systems have the potential to improve the accuracy and repeatability of surgical procedures by means of digital preoperative planning and intraoperative tracking of the patient and surgical instruments.One area where the accuracy and repeatability of computer-assisted interventions could prove especially beneficial is the treatment of osteochondral defects (OCD). OCDs represent a common problem in the patient population, and are often a cause of pain and discomfort. The use of synthetic implants is a valid option for patients who cannot be treated with regenerative methods, but the outcome can be negatively impacted by incorrect positioning of the implant and lack of congruency with the surrounding anatomy.In this paper, we present a novel computer-assisted surgical workflow for the treatment of osteochondral defects. The software we developed automatically selects the implant that most closely matches the patient’s anatomy and computes the best pose. By combining this software with the existing capabilities of the Navio™ surgical system (Smith &amp; Nephew inc.), we were able to create a complete workflow that incorporates both surgical planning and assisted bone preparation.Our preliminary testing on plastic bone models was successful and demonstrated that the workflow can be used to select and position an appropriate implant for a given defect.

This study reports on the one-year clinical results and patient reported outcomes (PROMs) associated with a new ‘predictive balance’ tibia-cut first total knee arthroplasty (TKA) technique that uses a robotic ligament tensioner. PROMs are compared to registry data and historical results in the literature.Five hundred and thirty-three patients were prospectively enrolled and underwent robotic TKA (mean age: 67.7±8.4; females: 320; BMI: 31.2±4.9). Pre-op, three, six and 12-month WOMAC, UCLA activity scale, and HSS-Patient satisfaction assessments were completed by 533, 352, 314, and 256 patients, respectively, and compared to WOMAC registry data from the Shared Ortech Aggregated Repository (SOAR) and to historical satisfaction reports in the literature.Despite having equivalent baseline PROM scores, predictive balance patients had significantly higher WOMAC scores at all post-operative timepoints (p&lt;0.001) and higher UCLA activity scale scores at 3M and 6M (p&lt;0.013). Overall patient satisfaction in the predictive balance cohort was 91.2%, 92.4%, and 96.5% at 3M, 6M and 1YR, respectively. Average length of stay was 1.6 days (±0.8). Surgical complications in this cohort were typical of TKA.Limitations to this study include the lack of a closely matched control group. Nonetheless, first year results are promising with improved objective measures compared to large registry databases and recently reported patient satisfaction measures.

As technology drives improvement in healthcare, the utilization trends for robotics in arthroplasty has continued to increase over the last decade. With the growth of robotics, we must determine if the proposed benefits are worth the increased cost. The purpose of this study was to evaluate inpatient post-operative and post-discharge outcomes of robotic-assisted surgery vs. conventional manual instrumentation, specifically time to discharge, discharge status and opioid consumption post- operatively. Knee Injury and osteoarthritis outcome score (KOOS) was calculated for each group as well.After IRB approval, a retrospective chart review of 100 robotic assisted primary total knee arthroplasty (TKA) and 100 matched controls undergoing conventional TKA was performed. Baseline demographics were recorded as well as post-operative outcomes including length of stay, opioid consumption, discharge status and duration of opioid use. All patients underwent primary TKA from 2016-2018 with minimum 6- month follow-up by a single fellowship trained arthroplasty surgeon at a high-volume joint center. Exclusion criteria included &lt; 6 month f/u, incomplete chart information, inflammatory arthritis, BMI &gt;40.Patients had similar pre-operative demographics including age, BMI, gender, opioid use and baseline depression rates. The robotic assisted TKA group had statistically significant decreased LOS (1.58 vs. 2.18 p&lt; 0.001) and morphine equivalents during their hospital stay (73.52 vs. 102.50 p&lt; 0.02). The robotic group had fewer patients at six weeks requiring opioids (37 vs. 61 p=0.001). Six month post- operative KOOS was 81.73 in the control group and 78.22 in the robotic group, (P&gt;0.05).Robotic-assisted TKA was associated with statistically significant decreased hospital LOS, morphine equivalents, and opioid usage at the 6-week follow up appointment. KOOS for the groups in our study were not statistically different. Although KOOS in the control group trended to be higher, our average KOOS for both cohorts was higher than the national average of 76.8.

Cup orientation is a challenging step in total hip arthroplasty (THA), to ensure comfort of the patient and durability of the prosthesis. The safe zone defined by Lewinnek is commonly used for cup orientation, but it is nowadays being questioned because it is not patient-specific.We propose to define a new safe zone for cup orientation, that considers patient-specific parameters such as the pelvic tilt and the range of motion (ROM) of the leg.We developed a software that easily computes a unique safe zone from these param- eters in different daily positions, ensuring a cup orientation without risks of prosthetic impingement.

The recent studies about iliosacral screws performed with navigation systems show promising results. The Surgivisio system is a new generation of intraoperative 3D imaging technique used in our institution since two years. The aim of this prospective study was to evaluate the accuracy of iliosacral screw placement and radiation exposure with the Surgivisio® system.Between January 2018 and December 2019, every patient operated for percutaneous iliosacral screwing using the Surgivisio® system were included in this prospective single center study. Accuracy of screw placement was assessed with post-operative high- resolution CT-scan. Operative time, radiation exposure and complications were assessed.A total of 32 patients were included with 49 iliosacral screws. Using the modified Gras classification, 2% (1/49) were rated as misplaced and 2% (1/49) were repositioned. The mean operative time was 26 min for the whole procedure. The mean dose area product was 7.98 Gy.cm2. Two complications were recorded (neurological pain treated by removal of the misplaced screw, an asymptomatic cement leakage with one augmented iliosacral screw).The Surgivisio® system is an efficient navigation tool for iliosacral screwing in minimal invasive surgery. It improves the accuracy of screw placement with an acceptable radiation exposure and operative time.

Authors: Mahawar Krishna 
Published: September 2020

I consider Phad Painting as a valuable pilgrimage of Rajasthan. Phad painting (Mewar Style of painting) or Phad is a stye religious scroll painting and folk painting, practiced in Rajasthan state of India. This is a unique scroll making folk art; this style of painting is traditionally done on a long piece of cloth or canvas, known as phad. It is synonymous with the Bhopa community of the state.
These are beautiful specimen of the Rajasthani cloth paintings. The narratives of the folk deities of Rajasthan, mostly of Pabuji and Devnarayan- who are worshipped as the incarnation of lord Vishnu & Laxman. Each hero-god has a different performer-priest or Bhopa. The repertoire of the bhopas consists of epics of some of the popular local hero-gods such as Pabuji, Devji, Tejaji, Gogaji, Ramdevji.The Phad also depict the lives of Ramdev Ji, Rama, Krishna, Budhha & Mahaveera. The iconography of these forms has evolved in a distinctive way.
Shahpura in Bhilwara district of Rajasthan are widely known as the traditional artists of this folk art-form for the last two centuries. Presently, Shree Lal Joshi, Nand Kishor Joshi, Prakash Joshi and Shanti Lal Joshi are the most noted artists of the phad painting, who are known for their innovations and creativity. Noted examples of this art are Devnarayan Ki Phad and Pabuji Ki Phad.

Indian folk arts establish the ethos of life and the foundation of folk culture. The culture and civilization of Nimar can be seen in folklore, folklore, folk paintings. The inclusion of symbols in the making of various Teej-festivals folk paintings shows the presence in their sociality. Parallel development of a beautiful beautiful painting tradition of land ornamentation with paintings made on the occasion of rituals. The design of geometrical form is reflected in land ornamentation. Jyoti, Nag, Kuldevi, Dussehra, Bhayuduj, Sureti, Ahoi Ashtami, Sanjhafuli, Diwali Hatay, Manna, Satiya, Check Kalash etc. are prominent in the mural paintings. The basic feeling of folk paintings is graphical. For illustration, the primary colors are red, yellow, blue, green, black and white, etc. The artist prepares the traditional method. There is no definite rule of color legislation in folk paintings and styles of making paintings are like stereotypes. Every activity in life tries to express in pictures the folk artist. Due to the influence of modern modernity, activities related to the picture tradition are now getting reduced. There is a need to save these colors so that this art flourishes.

History and Language in Tennyson’s Tragedy Harold (1876)
Authors: M. Fahmi Saeed  Ismael , A. Dabbagh Lanja 
Published: September 2020

Alfred Tennyson (1809- 1892) wrote a compact, action- packed, historical, patriotic, and a pioneering tragedy inspired by the Norman Conquest of England entitled Harold in 1876. It is based on the facts regarding the events leading to the Battle of Hastings in 1066. Tennyson has been, so far, the only man- of- letters to have dramatized this chapter of British history in a tragedy, even though he has never been the only writer to have paid attention to this turning- point in the destiny of his homeland. This tragedy focuses on the personal conflict between Harold Godwinson (1022- 1066) and William Duke of Normandy (1028- 1087), also known as William the Conqueror, or King William I. This drama, thus, is a journey to the past to explore the forces at work, and the men who made history, the struggle to achieve an improvement after the long- lasting social and cultural stagnation of England in Anglo- Saxon days which had lasted from 449- 1066. Tennyson chose the historical moment which all the earlier playwrights had avoided. Alongside this, he chose the accurate kind of discourse that would be more suitable for both the historical theme and the historical period.
The paper considers and clarifies the notable presence of language and its use as an indication of the historical course of the work. This is carried out through the analysis of a number of selections from the text. The focus will be on the historical style of the dramatic discourse. Tennyson is faithful as much as possible not only to the events but to the historical kind of speech used by characters to make a convincing and trustworthy play linguistically and historically. The paper considers and clarifies the notable presence of language in its use in historical context of this tragedy.
