The clinical and functional outcome of arthroscopic bankart repair in recurrent shoulder dislocation

Abstract

Background: Study aimed to assess the functional and clinical outcome of arthroscopic bankart’s repair in recurrent shoulder dislocation using UCLA & SST scoring system.Methods: It is a prospective cohort study conducted on the 28 patients undergoing arthroscopic bankart’s repair for recurrent shoulder dislocation in the department of orthopaedics at vydehi institute of medical sciences and research centre, bengaluru from September 2017 to October 2019. Patients aged between 18-50 years of both genders undergoing arthroscopic bankart repair with anterior instability of glenohumeral joint with at least ≥2 episode of dislocation/subluxation, a positive clinical apprehension test and radiological evidence of glenohumeral instability and glenoid bone loss < 25% were included in the study and patients with glenoid bone loss >25%, contact sports athletes, previously failed arthroscopy or open surgery, seizure disorder, multidirectional instability/habitual dislocation were exclueded. Each case was followed post operatively for atleast 1 year.Results: This series consisted of 28 patients, with the mean follow up period of 12 months, the mean pre-operative UCLA score of 18 improved to 31.75 post operatively, the mean pre-operative SST score of 4.89 improved to 10.96 post operatively. Out of 28 patients none had episodes of recurrent dislocation and anterior translation or apprehension. External rotation in 90º of abduction improved in 25 patients (89%).Conclusion: we conclude that arthroscopic bankart’s repair in recurrent shoulder dislocation with suture anchors is a reliable procedure with respect to shoulder function, recurrence rate and range of movement.
