Since 1994, 51 patients have undergone arthroscopic repair of superior labrum anterior and posterior (SLAP) lesions. There were 45 men and 6 women ; the average age was 29 years (range, 16 to 63 years). There were 43 thorowing arthletes, 8 heavy laborers, and 38 right and 13 left shoulders. No patient had an inflammatory disease or condition that would have affected our results. The average follow up period was 4 years (range, 0.5 to 7.5 years). In all cases the specific diagnosis was confirmed arthroscopically : SLAP type I was found in 4 cases, type II in 41 cases, type III in 2 cases, and type IV in 4 cases. Our operative indications are SLAP type II on MR arthrogram (MRA) or SLAP type I, type III and type IV, which is indistinguishable from SLAP type II on MRA. Operative treatment was performed arthroscopically for SLAP type I (debridement, 4 cases), type II (Caspari, 8 cases, suture anchor of the biceps tendon to the bony superior glenoid, 33 cases), type III (suture anchor 2 cases). In some type IV lesions, an additional procedure was used (suture anchor, 1 case, with debridement open tenodesis, 3 cases). Eleven of the cases (22%) had cuff tear (SLAP type II, 9 cases, type III, 1 case, and type IV, 1 case), which were arthroscopically repaired. We used Japan Shoulder Society (JSS) sports score to evaluate our clinical and functional results. Improvements were significant. All patients had good results and returned to their previous levels of activity. Arthroscopic repair of the detached and floating biceps labrum complex gave excellent early results, restored the anatomical configuration and provided good stability.
