Functional outcomes in single stage bilateral ACL reconstruction with a maximum follow up of 10 years.

Background: Bilateral ACL injuries are a rarity and there is no particular consensus on whether this rare problem has to be tackled in stages or in a single stage. There are a few studies and case reports in the literature about the outcomes in single staged bilateral Anterior cruciate ligament reconstruction (ACLR). This study is focused on functional outcomes after a single staged bilateral ACLR, as well as impact of simultaneity of the injury, meniscal tears, notch stenosis and hyperlaxity. Materials and methods: A retrospective study was conducted from 2013 to 2021. Patients with bilateral ACL injury either simultaneous or non simultaneous, with or without meniscal tears were included in this study. Pre operative diagnosis was made both clinically and by MR imaging. All patients underwent a single staged bilateral ACL reconstruction. Pre operative functional scores (IKDC and Lysholm) were taken at admission and patients were examined at regular follow ups. Final functional scores were collected in a phone interview. Results: 33 patients underwent bilateral ACLR in a single stage during the study period but one patient had revision ACLR in one knee and so was excluded. Of the 32 patients, 25 (78%) had non simultaneous injury and 7 (22%) had a simultaneous injury, meniscus tear was noted in 27 (84.4%), notch stenosis in 19 (59.3%) and hyperlaxity in 12 (37.5%). IKDC and Lysholm scores have improved postoperatively. No statistically significant difference was found with or without simultaneous injury or meniscus tears. Conclusion: Single stage bilateral ACL reconstruction is a safe, reproducible approach to bilateral ACL injuries whether they were simultaneous or non simultaneous or with or without meniscal tears.

When to Do Selective Patellar Resurfacing in Total Knee Arthroplasty: A Decision-Making Algorithm Based on Pre-operative and Intra-operative Findings.

Background: Persistent anterior knee pain post total knee arthroplasty (TKA) is a significant cause of patient dissatisfaction. Selective patellar resurfacing is commonly practiced for primary total knee replacement (TKR) but there is a paucity in literature regarding its decision making. Study Objective: This study aims to develop a decision-making algorithm for selective patellar resurfacing using Hospital for Special Surgery Patello-femoral Assessment score (HSS PFA score), weight-bearing patellofemoral X-ray, and intraoperative cartilage wear assessment based on the Outerbridge classification. Materials and Methods: This prospective study enrolled 65 patients, assessing preoperative factors including HSS PFA score and Baldini view radiography. Intraoperative cartilage wear was categorized using the Outerbridge classification. Preoperative findings were correlated with intraoperative outcomes through statistical analysis, leading to the development of a predictive algorithm. The efficiency of algorithm was assessed at 3-year follow-up using HSS PFA score. Results: A significant negative correlation (r = - 0.272, p = 0.029) was observed between HSS PFA score and cartilage wear. However, no significant relationships were established between HSS PFA score and Baldini view observations, including radiological tilt (p = 0.517) and displacement (p = 0.277). Intraoperative cartilage wear versus patellar tilt (p = 0.65) and displacement (p = 0.837) also yielded non-significant results. Three-year follow-up examinations revealed no complications and significant HSS PFA score improvements in all patients. Conclusion: The requirement for patellar resurfacing can be predicted using a combination of preoperative parameter such as HSS PFA score and the intra-operative cartilage wear. We put forward an algorithm based on above findings to aid in the decision making.

Effect of ascending and descending medial open wedge high tibial osteotomy on patella height and functional outcomes-a retrospective study.

BACKGROUND: High tibial osteotomy (HTO) is a popular joint-preserving option for medial compartmental osteoarthritis. However, this is associated with alterations in the patellar height (PH) and tibial slope (TS). This study aims to compare the effect of ascending (AMHTO) and descending medial opening wedge HTO (DMHTO) on patella height, posterior tibial slope and functional outcomes. MATERIAL AND METHODS: A retrospective study was conducted between February 2018 and July 2021. Patients with medial compartment osteoarthritis, varus alignment, and complete pre- and postoperative lateral and full-length anteroposterior radiographs were included. Pre- and postoperative radiological measurements include the Caton-Deschamps index (CDI), the mechanical axis deviation (MAD), and the posterior tibial slope. The functional outcomes were measured using the Oxford Knee Score (OKS), Lysholm Knee Score (LKS), and Tegner Activity Scale (TAS). The osteotomy union was checked with serial X-rays every 6 weeks till a satisfactory union was achieved. RESULTS: Fifty-eight patients were included in the study. Thirty-four (58%) patients received AMHTO, and 24 (42%) received DMHTO. There was no baseline difference in the demographic variables or functional scores between the two groups. The preoperative mean MAD of - 9.65° ± 3.67° was corrected significantly to + 0.08 ± 2.80° (varus -, valgus + , P = 0.034). A significant difference in preoperative and postoperative CDI of 0.93 ± 0.45 and 0.83 ± 0.27, respectively, was noted (P = 0.023). In the AMHTO group, a statistically significant decrease in PH from preoperative 1.03 ± 0.77 to 0.84 ± 0.12 was noted (P = 0.003). There was a significant improvement in functional outcomes between baseline and 9-month follow-up in both groups. There was no significant difference between the functional outcomes of the two groups at 9-month follow-up. CONCLUSION: The study confirmed our hypothesis that descending HTO caused less alteration in the patella height compared to ascending HTO. There is no significant difference in the functional outcomes between the groups. However, in patients with PFOA, and when attempting higher degree of correction through AMHTO, the possibility of worsening of symptoms due to change in PH must be considered.

The Modified PROMT Score: A Better Prognosticative Tool to Assess Traumatic Meniscal Tear Reparability.

Background: Considering various factors that influence meniscal repairability, Ortho One PROMT score (OPS) was proposed in 2019. With an increased understanding of factors influencing meniscal repair and by analysis of OPS predictions and repair results, a modified PROMT score (MPS) has been formulated. The objective of this study is to assess the superiority of MPS over OPS. Methods: Age, chronicity, and pattern of tears were found to be important contributors to false-negative results of OPS. Considering these factors, MPS was designed. A prospective, double-blinded study was conducted between November 2020 and May 2021. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, negative predictive value, and accuracy of both scores were calculated. Receiver Operating Characteristic (ROC) curve was plotted. Results: Of 133 meniscal tears, 100 met the inclusion criteria. In predicting meniscal repairability, OPS demonstrated sensitivity and specificity of 90.32% and 83.33% medially and 64.71% and 79.41% laterally. MPS had sensitivity and specificity of 96.77% and 88.89% medially and 82.35% and 88.24% laterally. Both scores showed good statistical significance (p < 0.05) in predicting meniscal reparability. For medial meniscus repairability, area under the ROC curve was 0.868 for OPS and 0.928 for MPS. For lateral repairability, the area under the curve was 0.721 for OPS and 0.853 for MPS. Conclusion: MPS will serve as a simple and more effective tool for surgeons to predict meniscal repairability, thus enhancing their pre-surgical preparedness. This tool will also help surgeons to realistically counsel their patients and to achieve optimal patient.

Trends in Primary Anatomical Single-Bundle Anterior Cruciate Ligament Reconstruction Practice in Adult Patients Prevalent Among Arthroscopy Surgeons of Six Southern States of India.

Background: Although guidelines from multiple scientific studies decide the general trend in ACLR practice, there is often a variation between scientific guidelines and actual practice. Methods: A 17-member committee comprised of sports surgeons with experience of a minimum of 10 years of arthroscopy surgery finalized a survey questionnaire consisting of concepts in ACL tear management and perioperative trends, intraoperative and post-operative practices regarding single-bundle anatomic ACLR. The survey questionnaire was mailed to 584 registered sports surgeons in six states of south India. A single, non-modifiable response was collected from each member and analyzed. Results: 324 responses were received out of 584 members. A strong consensus was present regarding Hamstring tendons preference for ACLR, graft diameter ≥ 7.5 mm, viewing femoral footprint through the anterolateral portal, drilling femoral tunnel from anteromedial portal guided by ridges and remnants of femoral footprint using a freehand technique, suspensory devices to fix the graft in femur and interference screw in the tibia and post-operative bracing. A broad consensus was achieved in using a brace to minimize symptoms of instability of an ACL tear and antibiotic soaking of graft. There was no consensus regarding the timing of ACLR, preferred graft in athletes, pre-tensioning, extra-articular procedure, and return to sports. There was disagreement over hybrid tibial fixation and suture tapes to augment graft. Conclusion: Diverse practices continue to prevail in the management of ACL injuries. However, some of the consensuses reached in this survey match global practices. Contrasting or inconclusive practices should be explored for potential future research.

Current concepts review in the management of subscapularis tears.

Subscapularis (SSc) is the prime internal rotator of shoulder. It is the most powerful rotator cuff muscle, maintaining the anterior force couple of shoulder. The tears in SSc as any other rotator cuff muscles might result from a traumatic event or more commonly from intrinsic degeneration. With the advent and widespread use of shoulder arthroscopy, SSc tears, which were once considered as "forgotten or hidden lesions" are now being increasingly recognized. Isolated SSc tears are relatively rare. They occur in combinations. Clinically internal rotation can be near normal because of the compensation provided by other internal rotators. It is not uncommon for patients with SSc tear to be normal on routine physical examination. The Bear Hug test (BHT) has high sensitivity and accuracy in the diagnosis of SSc tear. The combined use of BHT with Belly Press Test has been found optimal for diagnosis. US is an accurate and reliable method for diagnosing SSc tears and outperformed MRI in diagnosing partial-thickness SSc tears. The MRI is currently the most advanced imaging available for diagnosis. The specificity is up to 100%. However, the sensitivity is between 36 and 40%. The earliest classification system for SSc tears was by Fox et al. The commonly used classification is by Lafosse et al. The recent system by Yoo et al. is based on the insertion of SSc. The comma sign is gaining importance not only in arthroscopic diagnosis but also in MRI identification and repair of SSc. The mode of management is mainly arthroscopic. The techniques of repair of SSc are continuously progressing. However, there is no clear consensus on the double vs single-row repairs, biceps tendon management, and the role of coracoplasty. Future research must focus on these areas. Reserve shoulder arthroplasty is reserved for salvage in older age groups. Tendon transfers are performed in young active individuals with irreparable tears.

Prophylaxis for preventing venous thromboembolism in knee arthroscopy and soft tissue reconstruction: consensus statements from an international panel of experts.

PURPOSE: There is a lack of consensus regarding need for Venous Thrombo Embolism (VTE) prophylaxis following arthroscopic knee surgery and open soft tissue knee reconstruction. Clear cut guidelines like ones for trauma surgery and arthroplasty do not exist and the published literature is limited to case reports with a few society guidelines. Given this lack of consensus, we conducted a modified Delphi questionnaire of international experts to provide recommendations on this topic. METHODS: The consensus statements were generated using an anonymised 3 round modified Delphi questionnaire, sent to an international panel of 38 knee surgeons, with an 80% agreement being set as the limit for consensus. The responses were analysed using descriptive statistics with measures like mode, median and box plots. Feedback was provided to all panelists based on responses from the previous rounds to help generate the consensus. RESULTS: Six consensus statements were generated after the three rounds of Delphi. Patient factors, prolonged surgery duration and family history of thrombogenic events emerged as the main points to be taken into consideration for prophylaxis. CONCLUSION: It was established through this study, that there exists a select group of patients undergoing arthroscopic surgery that justify the usage of VTE prophylaxis. The expert responses to most of the questions in different scenarios favoured usage of VTE prophylaxis based on patient factors like advanced age, past history of VTE, smoking, oral contraceptive use etc. LEVEL OF EVIDENCE: Level V.

Interlinked Hamstrings for Combined Anterolateral and Anterior Cruciate Ligament Reconstruction: A Novel Technique for ALL.

Background: Anterolateral ligament (ALL) reconstruction provides rotational stability in patients undergoing anterior cruciate ligament (ACL) reconstruction. The aim of this study was to assess the outcome of patients who underwent combined ACL and ALL reconstruction with a novel anatomic technique using hamstring tendon autograft and fixed loop suspensory device. Methods: From 2016 to 2018, 25 patients who underwent combined reconstruction of ACL and ALL in our Institution were evaluated retrospectively. International Knee Documentation Committee (IKDC) Score, Tegner Lysholm Knee Score, grade of pivot shift was assessed at a final follow-up. Results: Mean follow-up was 31.5 months (28-42). Mean IKDC (81.5) and Tegner Lysholm (82.8) Knee Scores improved significantly at a final follow-up, with all knees demonstrating negative pivot shift. All patients had good outcomes at 2 years follow-up with no graft failure and with no residual instability. Conclusion: ACL and ALL reconstruction using this technique described for the anterolateral instability of the knee was satisfactory in our patients. This technique is simple, easily reproducible and avoids additional implants for ALL in the tibia. Level of evidence: IV.

Can ACL Tears be Restricted to Sports Injuries Alone? A Retrospective Analysis.

BACKGROUND: The number of people injured following a road traffic accident (RTA) are as high as 2-5 crores around the world every year. The literature from western population suggests that ACL injuries are encountered mostly following high velocity sports injuries in clinical practise. But, in India there are a large group of individuals presenting with ACL injuries following RTAs. METHODS: We performed a retrospective analysis of all patients with ACL injuries presenting to our hospital following RTAs. All the information pertaining to the ligaments injured, vehicular factors, time of the day and environmental factors were recorded. The data was then analysed statistically. RESULTS: Most injuries occurred in the 31-40 year age group and velocity in the same range. Injuries due to bike skid predominated in our study amounting to 55.9%. Interestingly, very low velocities accidents due to stray dogs accounted to 43.8% and they occur mostly at night. CONCLUSION: The number of patients presenting with RTA related ACL injuries in our country are numerous. Hence, we have made an attempt to show that ACL injuries can occur even at low velocity following motor vehicle accidents in contrast to the western population, where sports related injuries are the most common etiology for such mishaps.

Open Classic Latarjet Procedure Performed Using Freehand Technique-Surgical Technique and Outcome.

INTRODUCTION: Latarjet procedure is commonly performed for recurrent anterior shoulder instability with glenoid side bone loss. Classic Latarjet procedure can be performed using specially designed drill guides, jigs, or by freehand technique. Here we have described a technical note on classic Latarjet procedure performed with freehand technique utilizing simple rulers and caliper. The functional and radiological outcomes of our patients have also been analysed. MATERIAL AND METHODS: 149 open classic Latarjet procedures were performed using our technique between March 2015 and July 2018. The mean age of the patients was 32.95 years (Range 22-59 years). The functional outcome of the patients was measured using Western Ontario Shoulder Instability (WOSI) and Oxford Shoulder Instability Score (OSIS) at 2 years of follow-up. Screw and graft positioning were studied in 24 consecutive patients with a postoperative computed tomography (CT) scan. RESULTS: There was no incidence of recurrent subluxation or dislocation post-surgery. Mean OSIS score increased from 15.63 ± 3.20 preoperatively to 42.44 ± 3.88 postoperatively (p value < 0.05). WOSI score decreased significantly from 62.54% ± 8.24 to 10.26 ± 6.33 postoperatively at 2-year follow-up (p value < 0.05). Postoperative CT scan also showed satisfactory screw placement in all patients. CONCLUSION: Open Latarjet procedure performed using freehand technique provides good functional and radiological outcomes in patients with recurrent anterior shoulder instability with glenoid side bone loss.

Lateral Epicondylitis-Narrative Review on Surgical Options for Recalcitrant Cases.

PURPOSE: Lateral epicondylitis or lateral elbow tendinopathy is a common condition which needs to be addressed appropriately. This condition usually responds well to non-operative treatment. However, an orthopaedic physician needs to be aware of the recalcitrant cases and equip surgical armamentarium to provide adequate care. METHODOLOGY: The literature search was performed on PubMed, Medline and Google scholar using the keywords Tennis elbow, recalcitrant, thorntons technique, surgical options, for this narrative review. CONCLUSION: This article focuses on the causes for recalcitrant tendinopathy and review of its surgical options.

Management Guidelines for Infection After ACL Reconstruction: Expert Opinion Statement Based on the Modified Delphi Survey of Indian Arthroscopy Surgeons.

AIM: Infection after anterior cruciate ligament (ACL) reconstruction, though rare, is a potentially devastating complication and the evidence-based recommendation on the various topics in its management is limited. The purpose of this study was to develop recommendations for the prevention and management of infections in ACL reconstruction surgery by performing a structured expert consensus survey using Delphi methodology. MATERIALS AND METHODS: 22 topics of relevance in the prevention and management of infection following ACL reconstruction were chosen from an extensive literature review. 30 panelists were requested to respond to a three-round survey, with feedback, to develop a consensus statement on the topics. RESULTS: Consensus statements could be prepared in eleven out of twenty-two topics including: the graft is retained at the first arthroscopic debridement, the graft is removed when repeated debridement are needed, and revision ACL reconstruction is needed only if the patient develops instability. Concurrence could be obtained in the topics including: longer duration of antibiotics is needed in immunocompromised patients, soaking graft in antibiotic solution reduces infection risk, and knee swelling without warmth does not suggest infection. CONCLUSIONS: A proper skin preparation, a longer course of antibiotics in immunocompromised patients, and soaking the graft in antibiotics reduces the risk of infection. In case of infection, a healthy-looking graft must be retained at the first debridement and if the graft must be removed, revision ACL reconstruction is advised only if the patient develops instability.

All arthroscopic medial meniscus inside out repair- Technical note.

Concomitant meniscal injuries are common in patients with anterior cruciate ligament (ACL) insufficiency. Along with ACL reconstruction, meniscal repair offers better outcomes. This requires multiple incisions for both procedures. We present a novel technique of medial meniscus inside out repair using only the tibial tunnel wound without making an additional posteromedial incision. This is the first such description of this novel technique in a 21 year old male who underwent ACL reconstruction along with bucket handle medial meniscal repair.

Concurrent Anterior Cruciate Ligament and Medial Patellofemoral Ligament Reconstruction: A Case Report and Literature Review.

Anterior cruciate ligament (ACL) insufficiency in combination with patellar instability are rare occurrences and are difficult to treat. Failure to address patellar instability in such cases may place excessive strain on ACL graft leading to graft rupture. We present three such cases treated by concurrent ACL and medial patellofemoral ligament (MPFL) reconstruction with hamstring tendon autografts. Two patients had MRI evidence of MPFL injury and one patient had intact MPFL on MRI. All patients had good outcome without any residual instability at final follow-up.

A new scoring system for prediction of meniscal repair in traumatic meniscal tears.

PURPOSE: Traditionally, MRI has not been used to predict meniscus tear reparability. An attempt has been made in this study to predict meniscal reparability using MRI, and a new scoring system to help with the same has been developed and tested. METHODS: Thirty repaired menisci were compared with equal number of meniscectomy cases retrospectively. Various clinical and radiological (radiographs and MRI) characteristics like chronicity of tear, pattern of tear, etc, were tabulated. Based on their association with the outcome of repair or meniscectomy, odds ratio of each attribute were calculated. A scoring system-Ortho One PROMT Score (Prediction of Reparability of Meniscal Tears)-to predict meniscal repair was formulated. Using this score, meniscus surgery outcomes were prospectively predicted in 120 cases and results tabulated. RESULTS: The newly devised Ortho One PROMT score predicted medial meniscus repair with a sensitivity of 90.9% and a specificity of 93.2% and medial meniscectomy with a sensitivity of 93.2% and a specificity of 90.9%. It predicts lateral meniscus repair with a sensitivity of 69.2% of patients and lateral meniscectomy with a sensitivity of 78.8% of patients. CONCLUSION: Ortho One PROMT score is a useful scoring system to predict the outcomes of meniscus surgery preoperatively. It uses a combination of clinical and radiological (MRI and plain radiograph) characteristics. With this scoring system, both the surgeon and the patient are better prepared preoperatively regarding the outcome of a particular meniscus surgery. The scoring shall make day-to-day arthroscopic meniscus surgery less stressful. LEVEL OF EVIDENCE: III.

Mechanical assessment of tripled hamstring tendon graft when using suspensory fixation for cruciate ligament reconstruction.

BACKGROUND: Tripling semitendinosus tendon for ACL graft preparation facilitates creation of longer and thicker grafts. Our objective was to evaluate the mechanical difference between tripled tendon grafts, prepared by three methods, by comparing with quadrupled tendon graft. METHODS: Bovine hind-foot hoof extensors were allocated to four groups. Group I had quadrupled graft construct. Tripled graft constructs were prepared by passing the tendon to the Endobutton CL loop and stitching the third strand to (i) the loop (in Group II) or (ii) to one strand(in Group III) or (iii)to loop and both tendon strands (in Group IV). The constructs were preloaded from 10 to 50 N at 0.1 Hz for 10 cycles, followed by 1000 cycles of sinusoidal loading between 50 and 250 N at a frequency of 0.5 Hz. The specimens were then subjected to load to failure test at the rate of 50 mm/min. Displacement with cyclic loading, load at failure and the mode of failure were noted. RESULTS: The load at failure was 957 ± 23.30 N (Mean ± Standard Deviation) in Group I, 590.8 ± 24.40 N in Group II, 682.6 ± 59.28 N in Group III and 963.4 ± 21.72 N in Group IV. The displacement with cyclic loading was 1.13 ± 0.11 mm in Group I, 4.908 ± 0.55 mm in Group II, 1.822 ± 0.55 mm in Group III and 1. 126 ± .018 mm in Group IV. There was no significant difference between the Groups I and IV with respect to the load at failure and displacement (p > 0.05). The values were significantly different in Group II and Group III (p < 0.01), when compared to groups I and IV. CONCLUSIONS: Tripled grafts have mechanical properties equivalent to quadrupled grafts only when the three strands are sutured together. Caution may be warranted when using suspensory fixation device with tripled tendons and the third strand must be securely attached to the loop of fixation device and to the other two strands.

Functional outcome of an early anterior cruciate ligament reconstruction in comparison to delayed: Are we waiting in vain?

BACKGROUND: Surgical techniques of ACL reconstruction (ACLR) have evolved over the past three decades along with debate regarding timing of reconstruction. It was a widespread belief that the timing of surgery was an important factor in determining the resulting stiffness after ACLR. Delayed rather than early reconstruction of the ACL is the current recommended treatment since it is thought to give a better functional outcome. However, there is no consensus in the literature regarding the optimal time of surgical intervention. The purpose of this study was to compare the range of motion and functional outcome in patients who underwent ACLR early with those that were delayed. MATERIALS AND METHODS: The patients were randomized into two groups; patients who underwent the procedure within three weeks were kept in Group I (Early) and those patients who were reconstructed after six weeks were categorized as Group II (Delayed). Hamstring grafts were used and a standard protocol of surgery and physiotherapy was followed. The range of motion, IKDC and Tegner scores were compared. RESULTS: A hundred and four patients underwent ACLR; fifty-three patients were grouped as Group I (Early) and fifty one as Group II (Delayed). The range of motion of both groups was comparable. The IKDC and Tegner scores were also comparable for early (Group I) ACLR and the patients who had their ACL reconstructed after a delay of at least 6 weeks (Group II). CONCLUSION: There are no clinical differences in terms of range of motion and functional results between early and delayed ACLR.

Tibial plateau slopes in Indian patients with or without anterior cruciate ligament injury: a magnetic resonance imaging study.

PURPOSE: To compare anterior cruciate ligament (ACL)-injured and ACL-intact patients as well as males and females in terms of tibial plateau slopes to determine their association with ACL injury. METHODS: Magnetic resonance images (MRI) of the knee of 310 male and 179 female skeletally mature Indian patients (mean age, 40 years) with (n=170+29) or without (n=140+150) ACL injury were reviewed. Their medial and lateral tibial plateau slopes (MTPS and LTPS), medial tibial plateau depth (MTPD), and lateral tibial plateau height (LTPH) were measured using MRI. RESULTS: The ACL-injured and ACL-intact groups were comparable in terms of MTPS (6.72º vs. 6.73º, p=0.07), LTPS (5.68º vs. 5.70º, p=0.09), MTD (1.74 vs. 1.73 mm, p=0.356), and LTH (2.21 vs. 2.22 mm, p=0.393). Males and females were also comparable in terms of MTPS and LTPS in both ACL-injured and ACL-intact groups. CONCLUSION: ACL-injured and ACL-intact patients as well as males and females were comparable in terms of the tibial plateau slope parameters.

Outcome of arthroscopic subscapularis tendon repair: Are the results improving with improved techniques and equipment?: A retrospective case series.

BACKGROUND: Rotator cuff tears are a common cause of shoulder pain and dysfunction. More recently, there has been a renewed interest in understanding the subscapularis tears. There are multiple articles in the literature showing the short term results of isolated subscapularis tendon repair. However, the midterm and long term outcome studies for arthroscopic subscapularis repair are few. This study evaluates the functional outcome after arthroscopic subscapularis repair. MATERIALS AND METHODS: The records of 35 patients who underwent an arthroscopic subscapularis repair between May 2008 and June 2012 were included in this retrospective study. The records of all patients were reviewed. There were 22 males and 13 female patients with mean age of 58.2 years (range 41-72 years). All patients had a complete history, physical examination, and radiographs of their shoulders. Visual analogue scale (VAS), range of movements, power of cuff muscles, and modified University of California at Los Angeles (UCLA) score were assessed. RESULTS: The mean followup was 2.8 years (range 2-4 year). Functional outcome after arthroscopic subscapularis repair has an excellent outcome as analysed by clinical outcome, VAS score and UCLA score. Results were analyzed and had statistically significant values. The VAS for pain improved significantly (P < 0.001), and the mean modified UCLA score improved significantly (P < 0.001) from 14.24 ± 4.72 preoperatively to 33.15 ± 2.29 at 2 years postoperative. According to the UCLA system, there were 22 excellent, 11 good, and 2 fair results. Around 95% of patients returned to their usual work after surgery. CONCLUSION: At a median followup of 2 years, 95% of patients had a good to excellent result after an arthroscopic subscapularis tendon repair. We conclude that the midterm results show that arthroscopic subscapularis repair remains a good option for the treatment of patients with subscapularis tendon repair.
