Abstract
AIMS: The aim was to evaluate the clinical and anatomic outcome of arthroscopic repair of type II SLAP lesions. MATERIALS AND METHODS: The senior author performed isolated repairs of 25 type II SLAP lesions in 25 patients with a mean age of 40.0 ± 12 years. All tears were repaired using standard arthroscopic suture anchor repair to bone. All patients were reviewed using a standardized clinical examination by a blinded, independent observer, and using several shoulder outcome measures. Patients were evaluated by magnetic resonance imaging arthrogram at a minimum of 1-year postoperatively. STATISTICAL ANALYSIS USED: Two-tailed paired t-test were used to determine significant differences in preoperative and postoperative clinical outcomes scores. In addition, a Fisher's exact test was used. RESULTS: At a mean follow-up of 54-month, the mean American Shoulder and Elbow Surgeons Shoulder Index (ASES) scores improved from 52.1 preoperatively to 86.1 postoperatively (P < 0.0001) and the Simple Shoulder Test (SST) scores from 7.7 to 10.6 (P < 0.0002). Twenty-two out of the 25 patients (88%) stated that they would have surgery again. Of the 21 patients who had postoperative magnetic resonance imaging arthrographys (MRAs), 9 patients (43%) demonstrated dye tracking between the labrum bone interface suggestive of a recurrent tear and 12 patients (57%) had a completely intact repair. There was no significant difference in ASES, SST, and patient satisfaction scores in patients with recurrent or intact repairs. CONCLUSIONS: Arthroscopic repair of type II SLAP lesions demonstrated improvements in clinical outcomes. However, MRA imaging demonstrated 43% of patients with recurrent tears. MRA results do not necessarily correlate with clinical outcome.
