Published: March 2017

Introduction: Radial meniscus tears are seen in young patients, especially with anterior cruciate ligament ruptures. Repair of complet radial meniscus tear is necessary for the meniscus functions. The most important factor for success of the meniscus repair is primary stability, but it is still unknown which technique is ideal repair technique. Aim: We developed a new suture technique named Cross Horizontal Loop(CHL). In this novel technique the contact between meniscal tissue and suture is more than Horizontal Loop(HL) that routinely used today. So, we think that this technique will provide better fixation than HL. We aimed to compare 2 repair techniques (CHL vs. HL) using human lateral menisci biomechanically with cyclic loading and load to failure tests Materials-Methods: We used 20 intact lateral meniscus obtained from patients that operated (total knee replacement) for varus gonarthrosis in our clinic. All menisci were cut radially. In the first group (n:10) menisci were repaired with standart horizontal loop technique, and in the second group (n:10) cross horizontal loop technique were used for repair. All specimens were tested with load to failure test after cyclic loading test (500 cyclus X 5-30 N). Results: Both groups have similar failure load (71,4±17,52 N vs. 77,9±28,49 N; p:0,559) and stiffness (24,46±19,19 N vs. 24,48±15,87 N; p:0,818). CHL group has less peak displacement (6,26±1,24 mm vs. 8,4±1,92 mm; p:0,010). Conclusions: This novel repair technique decreases the amount of displacement according to standard technique while as strong as standart technique routinely used. In this way; we believe that it will increase the rate of healing in clinical use. [Table: see text][Figure: see text]

Aim: According to the ethnic demographical backgrounds, gracilis(G), and semitendinosus(ST) tendon antropometric properties may vary among the individuals of Turkish and active sporter patient populations. In this study, aimed was to define the G and ST tendon proportional anatomical corellations intraoperatively prior to graft harvesting that are uniquely specific to the Turkish ethnicity. Materials-Methods: The study was begun with 50 active sporting patients who were undergone arthroscopic graft anterior cruciate ligament hamstring tendon reconstruction(aACLHTR) in 2013-2014 at our institution. 15 patients were excluded due to premature graft ruptures, and not meeting the minimum of 4hrs/w active sporting criteria. This retrospective cohort was conducted with a total of 35 knees. Inclusion criteria were; Turkish ethnicity, having been undergone aACLHTR between 2013-2014, having been at an age of 16-50 years, having eligible intraoperative antropometric records, having consistent postoperative follow-ups, having been diagnosed to have complete ACL tear, having no ipsilateral/contralateral, congenital/acquired limb deformities or trauma, surgery or lymphedema history. Exclusion criteria were unwillingness to give written consent, having been a premature graft rupture during harvesting, having insufficient data recordings to meet the eligibility criteria. All the surgeries were performed by one senior surgeon who was blind to the study. All the demographical data, and measurements were recorded by a research assistant who was blind to the study. Pearson correlation coefficients were calculated to detect linear relationship between numerical variables. Beta coefficients were estimated by univariate linear regression analysis. All analysis were performed by using SPSS for windows version 22.0 considering the P<0.05 as statistically significant. Results: Mean age 29.9±8.3, Female/Male ratio %8.6/91.4, Right/Left ratio %68.6/31.4, Mean BMI 27.2±4.5, Mean limb length 87.8±6.4 Mean ST length 26.8±2.1, Mean G length 24.06±2.2, Mean ST thickness 6mm±0.9, Mean G thickness 4.5±0.8. ST-G thickness, and ST-G length correlations were r=0.754, p=0.001, r=0.614, p=0.001 respectively. Univariate linear regression analysis revealed statistically significant relationships; 56.8% of variation in G thickness was explained by ST. 1 mm increase in ST thickness resulted in 0.68 mm increase in G thickness, and 37.7% of variation in G length was explained by ST. 1 mm increase in ST length resulted in 0.68 mm increase in G length. Conclusions: With the ST-G index, surgeons would be intraoperatively able to template aACLHTR with a more durable, and adequate planning of hamstring graft construct combination unique to sporters’ demographic specifics, and to sports’ biomechanical specifics. Thus, the possiblity of antropometrically inadequate graft combinations would be precautioned. [Figure: see text]

Authors: Karaaslan Fatih , Karaoğlu Sinan 
Published: March 2017

Background and Purpose: Characterization of the insertion site anatomy in anterior cruciate ligament reconstruction has recently received increased attention in the literature, coinciding with a growing interest in anatomic reconstruction. The purpose of this study is to report a modified novel transportal technique to approach the center of anatomical femoral footprint in anterior cruciate ligament (ACL) reconstruction and to investigate the accurate femoral tunnel position with 3-dimensional computed tomography (3D-CT). Materials-Methods: We evaluated 11 patients who underwent primary ACL reconstruction using a modified transportal technique to approach the center of anatomical femoral footprint in single bundle ACL reconstruction with hamstring autograft. Their femoral tunnel positions were investigated with 3D-CT postoperatively according to the quadrant method by three orthopedic surgeons. Results: According to the quadrant method with 3D-CT, the femoral tunnel was measured at a mean of 33,49% ± 5,59% from the proximal condylar surface (parallel to the Blumensaat line) and 32,93% ± 3,82% from the notch roof (perpendicular to the Blumensaat line) with good interobserver (intraclass correlation coefficients [ICC], 0,991and 0,858, respectively with 0,975 – 0,997%95 CI) and intraobserver reliability (ICC, 0.875 and 0.893, respectively with 0,663 – 0,956%95 CI). Conclusions: Our modified transportal technique is anticipated to provide anatomical placement of the femoral tunnel during ACL reconstruction than the former traditional transtibial techniques. This technique is reproducible and also easier to perform than classic transportal technique does not need extra arthroscopic portal. [Figure: see text]

Published: March 2017

Background: This study investigates the effect of microfracture as a bone marrow-stimulating(BMS) technique on rotatory cuff(RC) healing using a chronic RC tear model. Methods: Chronic retracted RC tendon tear model was created in the subscapularis(SSC) tendons of 20 New Zealand rabbits, bilaterally. The tendons were repaired after eight weeks using a single-row configuration with suture anchors. In right shoulders, tendons were repaired in a standard fashion(control group). In left shoulders, microfractures were performed on the SSC footprint before repair(microfracture group). The animals were sacrificed 8 and 16 weeks after repair. The repaired tendons were tested biomechanically for their ultimate failure load, linear stiffness and elongation at failure. Gross and histological evaluation of the tendon-to-bone healing was evaluated. Results: In every sample, the SSC tendon was attached to its footprint on the lesser tuberosity. In microfracture group, collagen fibers were organized in relatively ticker bundles at both time intervals. The mean ultimate failure load of microfracture was significantly greater than that of control group at 8 (148.4+31 N vs. 101.4+26 N; p=0.011) and 16 (155+30 N vs. 114.9+25 N; p=0.017) weeks after repair, respectively. There were no significant differences between the two groups at each time interval for linear stiffness (15.9+2.7N/mm vs. 15.8+1.3N/mm, p=0.798 and 16.9+4.3N/mm vs. 17.1+3.6N/mm, p=0.848, respectively) and elongation at failure (4.7+1.1 mm vs. 4.7+1.3 mm, p=0.848 and 4.8+1.5 mm vs. 4.9+0.9 mm, p=0.749, respectively). Conclusions: The BMS technique of microfracture on the tuberosity of the repaired chronic rotator cuff tear promotes the dynamic tendon healing with significant ultimate force to failure and apparent microscopic findings.

Purpose: The purpose of this study is small hole microfracure method comparing with traditional microfracture method and investigation of effect of HA based acellular matrix scaffold on microfracture area. Materials-Methods: 21 Twenty-one New Zealand white rabbits were used for the in vitro portion of this study, bilateral knee joint from the same rabbit were same technic. An articular cartilage defect was established in the femoral trochlear groove about 5 mm. Control group was established alone microfracture (MF). 6 groups were formed in this study and each group has 3 rabbits and their six knees. In 3 groups were applied different number of small diameter hole microfracture (4,5,6 small holes microfracture respectively)and the other 3 groups were applied different number of small diameter hole microfracture (4,5,6 small holes micro fracture respectively added HA based acellular matrix scaffold in the same size ostechondral lesion. The regenerated tissues were harvested for gross morphology, histology at 12 weeks postoperatively. Results: Cartilage were regenerated, maintaining a constant thickness of cartilage. MF group has worse Wakitani scores than 6 small diameter holes mıcrofracture groups(group 6 and group 7) in either parameter of the score. (p=0,043, p=0,016) Matrix addition did not contribute to healing. (p=1,000) Conclusions: Increasing number of the small diameter holes microfracture (minimum %15 of defect size) improves cartilage repair compared with traditional MF in the same size ostechondral lesion. Also small diameter holes microfracture combined with HA-based AM implantation didn’t result in improved quality of the regenerated cartilage tissue.

Objectives: Osteoarthritis (OA) and vitamin D deficiency are common health conditions in older people. Whether vitamin D concentration is associated with knee OA is controversial. In this study, we aimed to determine the association between serum concentrations of vitamin D and osteoarthritic knee pain. Subjects and Methods: Vitamin D concentrations were measured with the 25 hydroxyvitamin D test in patients presenting with clinical symptoms of primary knee osteoarthritis. Osteoarthritis was graded on the Kellgren-Lawrence grading scale from anteroposterior and lateral radiographs. Height, weight, and body mass index (BMI) were recorded. Patients completed a 10-cm visual analogue scale (VAS) for indicating pain and the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Vitamin D concentration was defined as severely deficient (<10 ng/mL), insufficient (10 to 19 ng/mL), or normal (20 to 50ng/mL). Results: Of 149 patients (133 women) the mean age was 63.6 years. Mean vitamin D concentration was 11.53 ng/mL, and 90% patients were Vitamin D deficient. Mean WOMAC score was 57.2, and VAS pain score was 7.5. Kellgren-Lawrence grade was 2 for 10 patients grade 3 for 61, and grade 4 for 88. Mean BMI was 33.4. Mean values of VAS, WOMAC, and BMI did not differ by vitamin D status. Conclusion: Serum vitamin D concentration is not associated with knee pain in patients with osteoarthritis.

Published: March 2017

Purpose: Interosseous cysts located in calcaneal sulcus are radiologically diagnosed as ganglion cysts. However there is not enough evidence in the literature about their treatment and how they occur. We think that these cysts may cause hind foot pain by causing peripheral bone edema of the calcaneus or mucoid fluid production which further increases subtalar intra articular pressure. Methods: We performed surgical treatment for calcaneal sulcus cyst to 6 patients in 2015. All patients were evaluated with AP and lateral ankle X-ray and MRI preoperatively. Results: We found that all cysts were arisen from insertion of the interosseous talocalcaneal ligament in calcaneal sulcus by MRI ( figure 1 ). There were accompanying bone edema in 3 patients whose cysts were larger. We performed subtalar arthroscopy with drilling to 2 of the patients whose cysts were small. 3 patients were operated with curettage and grafting (autograft) by lateral approach. Last patient were treated with drilling by lateral approach. We detected the mucoid fluid stretching joint capsule when we reach subtalar joint during open surgery ( figure 2 ). Interosseous talocalcaneal ligament were intact in all patients treated even treated with open surgery or arthroscopy. Therefore cystic changes were not seen. In order to avoid ligament damage, cysts were curated and grafted with spongious bone through a small bone window. In a short follow-up period, complete pain relief without recurrence was observed. [Figure: see text][Figure: see text] Conclusions: During subtalar arthroscopy we saw that anterior of the posterior talar facet was impinged to talocalcaneal ligament insertion on the calcaneal sulcus. We suggest that cysts might occur as a result of recurrent oscillating trauma as Van der Vis et al. were postulated.

Aim: Dancers are professional athletes. Dance injuries resemble sports injuries, however, they push the limits of anatomy and physiology for rightful expression of the esthetics. In this study, we examined a group of dancers and injuries which required surgery to understand the associated factors (age, gender, dexterity, dance style) and also the time to return to their full capacity. Methods: 75 members of the Fire of Anatolia professional dance group (55 ethnic folk, 12 modern ballet, 8 Caucasian folk dancers) (mean age: 26.8±5.2; 17-38 years) performers were evaluated between the dates February 2009 and February 2016. The dancers suffered 14 orthopedic injuries requiring surgery during a six-year period. Nine of surgeries (64.2%) were the result of an acute trauma requiring meniscal repair in three due to meniscus tears, ACL reconstruction in two (one of them had to also undergo primary repair of the posterolateral corner of the knee) due to ACL tear, PCL reconstruction in one due to PCL tear, open medial patellofemoral ligament repair in one due to acute patellar dislocation, percutaneous fixation of the scaphoid in one due to scaphoid fracture and an extensor tendon repair of the hand in one due to extensor tendon cut. Five of the surgeries (35.7%) were due to chronic injuries consisting of deep infrapatellar bursitis treated by open bursectomy in one, arthroscopic fat pad resection due to Hoffa’s fat pad impingement in two, and arthroscopic resection of an symptomatic medial plica in two patients. Findings: Fourteen (12 male, 2 female; mean age: 30±5.45, range: 22 to 38) dancers out of 75 members (18.7%) of this high-demand dance group suffered injuries requiring surgery. Twelve (85.8%) of these injuries were at the knee joint and two (14.2%) were in the hand. There was no statistically significant difference between the mean ages of the dancers with and without injuries (p>0.05). Males suffered an injury 8.64 times more than females according to logistic regression analysis (p=0.003). Results: Male dancers are more susceptible to injuries that require surgery when compared to female dancers. All of the operated patients continue with their careers in dancing and arthroscopic surgery does not pose a threat to the career of the dancer. Level of Evidence: Level of evidence III.

Published: March 2017

Purpose: It is important to objectively measure symptoms and functional limitations related to patellar tendinopathy using outcome measures that have been validated in the language of the target population. Cross-cultural adaptations are also useful to enhance the understanding of the measurement properties of an assessment tool, regardless of the target language. The aim of the study to translate and adapt the Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire to Turkish. Methods: The translation and cultural adaptation were performed according to international recommendations. In the first stage, 2 Turkish individuals with a good command of English were responsible for the literal and conceptual translation of the VISA-P. The informed translator was a physical therapist, and the uninformed translator was a teacher. Both translators were fluent in English and spoke Turkish as their mother tongue. The translations were completed independently. In the second stage, both translations were compared and reviewed by a bilingual individual who highlighted any conceptual errors or inconsistencies in the translations to establish the first Turkish translation. In the third stage, after the first Turkish translation was agreed upon, 2 native English speakers with a good command of Turkish separately translated the finalized Turkish translation back into English. In the fourth stage, the back-translated version of the VISA-P was compared to the initial English version of the VISA-P. The committee evaluated the 4 translations and compared the discrepancies. After discussing the discrepancies, the committee finalized and approved the Turkish version of the VISA-P. In the final stage, prelimi-nary testing was performed. with 22 patients and 40 healthy participants to determine comprehension of the Turkish version. Results: Preliminary testing was conducted on 22 patients (12 male, mean ± SD age, 27.5 ± 6.6 years) who fulfilled the eligibility criteria and 40 healthy participants (30 male, mean ± SD age, 25.7 ± 4.9 years) of the study to determine comprehension of the Turkish version. The patients and healthy participants did not report any difficulties of the understanding of the questions. Conclusion: The VISA-P was translated and adapted to the Turkish language and can be used in clinical evaluation on the patellar tendinopathy. Additional studies are underway with the objective of evaluating the reproducibility and validity of the Turkish translation.

Published: March 2017

Objective: The weakness of the quadriceps strength in patellofemoral pain syndrome (PFPS) is very evident. Therefore, quadriceps strengthening exercises are very important part of the rehabilitation program. Neuromuscular Electrical Stimulation (NMES) is considered one of the methods for increasing quadriceps muscle strength. To evaluate the effectiveness of combined NMES and strengthening exercises to improve the recovery of quadriceps strength and function in patients with PFPS. Methods: This study was planned as a randomized controlled pilot study. A total of 27 patients (mean age=38.9±10.8 years, range=20-60 years; 16 females) with PFPS were assessed and randomly assigned into 2 groups. Group I received a standard program (quadriceps strengthening, hip strengthening and hamstring stretching) and NMES combined with quadriceps strengthening exercises simultaneously. Group II received the same standard program without NMES. Both groups were enrolled 3 times per week for 40 minutes per day in 6 weeks. Patients were assessed at the baseline, 3 rd, 6th, and 12th weeks of treatment. Quadriceps strength was evaluated by isokinetic dynamometer. The range of motion at testing was set between 0 for extension to 90 for flexion. The test was performed at 60 degrees/sn and concentric maximum peak torque value was recorded. Kujala and Lysholm scores were used for functional assessments. The data were analyzed using the SPSS 20.0. Shapiro-Wilk test was used to assess the distribution of data. The changes in dependent variables before treatment, 3 rd, 6th, and 12th weeks were analyzed using a 2 by 4 mixed-model analysis of variance (ANOVA). Pairwise comparisons with paired t test were used to determine whether the Group I or Group II, has changed over time. An intention- to- treat analysis was performed to impute values for missing data. An alpha level of 0.05 was established. Results: The study was completed with 20 patients. Group I (n=10; mean age=39.4±8.5 years; 7 females) and group II (n=10; mean age=43.2±11.7 years; 5 females) had no differences in pre-operative measures (p>.05). There was significant improvements in within groups statistics of all parameters for both groups (p<.05). No differences in quadriceps strength, Kujala and Lysholm scores between groups were found at the different time points (F= 0.86; p = 0.12, F=0,001; p =0.97, F=0.12; p=0.73, respectively) Conclusion: NMES combined with quadriceps strengthening exercises has no additional effect on PFPS patients’ on muscle strength and function. When considering these results, we believe that there is no need to continue the study in progress. [Table: see text]
