Arthroscopic bankart repair using suture anchors with respect to lesion of the middle glenohumeral ligament

ABSTRACT

Arthroscopic bankart procedures have been well described, and their results have produced a significant improvement over those of open repair or even those of other arthroscopic capsulorraphy techniques. Although injury to the middle glenohumeral ligament [MGHL] was discribed as a part of an avulsion of the entire anterior capsulolabral complex. A retrospective study was made on 42 patients with symptomatic anterior instability of the glenohumeral joint. The mean age was 24 yaers [20-32]. The instability was confirmed from preoperative history, physical examination, and magnetic resonance imaging which was positive in all patients. The arthroscopic findings showed ill-defined MGHL in 10 patients,and a cord like type in 5 patients a band like shaped ligament had been seen in the rest of the patient, associated injury with an anterior inferior glenoid labaral [AIGL] tear in 8 patients. Arthroscopic repair of glenoid labral tear with respect to MGHL using 2-3 suture anchors with a follow up of 2 - years resulted in decreased pain and improved function in all patients.There was no complication nore recurrence of the symptoms of instabity. 40 patients rated satisfactory on UCLA scale, the 2 patients rated unsatisfactory were complaining impingment, improved with arthroscopic subacromial decompression. Surgical arthroscopic repair of glenoid labral tear and avulsions of MGHL provides satisfactory results in a majority of cases
