Functional Outcome of Management of Isolated Supraspinatus Tendon Tear by Mini-open repair TechniqueA Prospective Interventional Study

Abstract

Introduction: Rotator Cuff Injuries (RCIs) are common shoulder injuries, and the supraspinatus muscle, which is part of the rotator cuff, plays a crucial role in shoulder abduction. The mini-open repair technique offers several advantages, including being less invasive, leading to reduced postoperative morbidity, and shorter operative times. Aim: The aim of this prospective interventional study was to assess the functional consequences of open microscopic repair and the functional implications of supraspinatus tendon repair following the procedure and during the postoperative healing period. Materials and Methods: The study was conducted at the Department of Orthopaedics at Great Eastern Medical School and Hospital in Srikakulam, Andhra Pradesh, India. The study duration was one year, from July 2020 to July 2022. A total of 120 patients aged between 20 and 60 years were included, and all surgeries were performed by the same surgeon. Patients were followed up for one year and evaluated with ConstantMurley Score (CMS) system. Patient data were analysed based on gender, age, degree of tears, clinical test results, and postoperative scores. Levene’s test was used to determine variance homogeneity, and the Student’s t-test (two-tailed, dependent) was used to determine the statistical significance of study parameters on a continuous scale within each group. Results: The study included 120 patients (84 males and 36 females), and the majority of them had traumatic tears. When data was analysed based on patient age, the majority were between 46 and 50 years (33 patients, 27%), followed by the age group of 41-45 years. At the end of one year, the outcomes were excellent in 68 patients, good in 24 patients, satisfactory in 16 patients, and poor in 12 patients. Conclusion: Based on the results of the mini-open technique, the authors concluded that mini-open rotator cuff repair resulted in superior repair integrity and shoulder function.
