SLAP tears occur at the superior glenoid labrum-biceps anchor complex, and generally are attributed to either acute trauma or chronic overuse. SLAP tears were first described by Andrews and later classified into 4 distinct subtypes by Snyder. Type II SLAP tears involve complete detachment of the biceps anchor from the superior glenoid, with the anterior and posterior labrum remaining intact. Although SLAP lesions are often associated with concomitant shoulder pathology (e.g., Bankart lesions, rotator cuff tears, acromioclavicular joint arthritis, glenohumeral chondral injuries), they can occur as an isolated lesion that can cause pain, mechanical symptoms, instability, and loss of range of motion causing patients to not be able to perform at the preinjury athletic level.

Several factors have been shown to potentially influence the management and outcomes of type II SLAP lesions including patient age, activity level, quality of labral tissue, and concomitant pathology. Initial management consists of activity modification, nonsteroidal anti-inflammatory drugs, physical therapy, or injections. Surgical treatment options involve either primary repair or biceps tenodesis (BT). Despite previous research, patient selection for repair versus BT is yet to be clearly delineated. Primary arthroscopic repair of type II SLAP lesions has traditionally been considered the gold standard in young patients with several studies reporting good to excellent results after repair. Conversely, BT has been favored in older patients because of lower failure rates, reduced pain, and higher rates of satisfaction and return to sport in comparison to repair. Recent work has shown that BT can be a reasonable option in younger patients who failed SLAP repair presenting the question whether younger patients should be managed with BT primarily.

The purpose of this study was to evaluate outcomes following open subpectoral BT for the treatment of isolated type II SLAP lesions in patients 45 years of age or younger and evaluate the rate of return to sport. We hypothesized that open subpectoral BT in the young population would be an effective treatment with a low revision rate and significant improvement in post-operative outcomes scores with a high rate of return to sport near preinjury level.
