title: Arthroscopic repair of isolated type II superior labrum anterior-posterior lesion.
abstract: The effectiveness of arthroscopic repair of type II superior labrum anterior-posterior lesion (SLAP) was unclear as previous studies examined this treatment with patients of combined types of SLAP lesions. To address this research gap, we evaluated the clinical and functional outcomes of arthroscopic repair for 16 patients (mean=24.2, SD=6.5) with clinical evidence of isolated type II SLAP lesion. After having arthroscopic stabilizations with Bioknotless suture anchors (Mitek), the patients were offered post-operative rehabilitation programs (e.g., physiotherapy) for 6 months. The symptoms of SLAP lesion and the functions of the shoulder were assessed pre-operatively and 28-month post-operatively by O'Brien test, Speed test, Yergason test, and University of California at Los Angeles rating for pain and function of the shoulder. Wilcoxon Signed Ranks test and McNemar test were employed to analyze the difference between assessment in pre-operation and post-operation phases. The result showed that patients' shoulder functions improved (UCLA Shoulder Score), and symptoms of SLAP lesion reduced (O'Brien test, Speed test, and Yergason test) significantly (P<0.05). Time for returning to play with pre-injury level was in average 9.4 months (range 4-24), and no complication or recurrence was detected. We concluded that arthroscopic repair is an effective operation of type II SLAP lesion with good clinical and functional outcomes; however, athletes with high demand of overhead throwing activities are likely to take longer duration of rehabilitation to attain full recovery.
