OUTCOME FOLLOWING SURGICAL REPAIR OF SLAP TYPE II LESIONS: A TWO-YEAR FOLLOW-UP



Abstract

Type II SLAP lesions account for 22–55% of all SLAP lesions and are described as detachment of the superior labrum along with the biceps anchor from the superior glenoid rim. This detachment may be associated with glenohumeral joint instability. The majority of SLAP lesions are associated with other pathologies such as rotator cuff tears, Bankart and other instability lesions. The purpose of this study was to evaluate the effectiveness of arthroscopic repair of type II SLAP lesions, two years following arthroscopic repair with suture anchors.

Data on thirty-eight consecutive patients (thirty-four males, four females, mean age: forty-five years, range, twenty-two to seventy years) were used for analysis. Outcome measures were the American Shoulder and Elbow Surgeons (ASES) assessment form and the Constant-Murley score. Thirteen patients had work-related injuries. Specific tests for SLAP lesion (i.e. New pain provocation test, O’Brien test, Yergason’s Test) were conducted pre-operatively.

Twenty-three patients had surgery on the right side. The O’Brien test was positive in 51% of the patients. The minimum follow up period was twenty-four months. Five patients had isolated SLAP type II lesion. Thirty-three had associated pathologies. Ten patients had rotator cuff repair. Twelve patients required acromioplasty and one patient underwent the long head of biceps tenodesis. Three patients had associated Bankart lesions. All patients showed significant improvement in ASES scores (p< 0.0001). However, Patients with work-related injuries did not show a significant improvement in Constant-Murley scores (p=0.20). Associated pathologies did not affect level of disability or subjective scores post-operatively. Strength did not change to a statistically significant level following SLAP repairs.

Arthroscopic SLAP repair provides significant improvement in subjective scores of the ASES. Patients with work-related injuries demonstrate a different pattern of recovery.
