Functional outcome and recurrence rate of arthroscopic bankart repair in Omani patients

Background: Traumatic anterior glenohumeral dislocation is one of the most common traumatic joint disorders in young and active individuals. Aim: To study the functional outcome and post-operative recurrence rate of recurrent shoulder instability operated by arthroscopic anterior stabilization in Omani patients. Study design: retrospective case series study. Methods: From 2015 to 2018, 69 patients underwent arthroscopic bankart repair at Khoula hospital, with a median follow-up of 20.49 months. Of these, 41 visited the clinic for scoring, while 29 were surveyed over the phone for recurrence using three scores: Oxford shoulder score, constant score, and Carter Rowe score. Results: Among the 70 patients 6 (8,5%) patients had recurrence of dislocation. With oxford shoulder score, 78% (32 patients) had satisfactory results and 17,1% (7patients) had mild to moderate and 7% (2 patients) had moderate to severe. At constant score, 36,6% (15 patients) of the patients had excellent results, 29,3% (12 patients) had good results 12,2% (5) patients had fair results and 22% (9 patients) had poor results. Patients not receiving post-operative physiotherapy had worse Rowe scores and Oxford functional outcomes. Military patients had worse results than labor workers, and labor workers performed worse than office workers. Conclusion: Anterior shoulder instability is challenging for young patients with high demands. External rotation deficit affects functional outcome and patient satisfaction. Results are comparable to published literature but recommend larger studies.
