Arthroscopic Treatment of a Type II Superior Labrum Anterior to Posterior (SLAP) Lesion Combined with a Bankart Lesion: Comparative Study between Debridement and Repair of Type II SLAP Lesion by the Status of Lesion.

Abstract

The purpose of this study is to evaluate results of superior labrum anterior to posterior (SLAP) repairs and debridement of type II SLAP lesions combined with Bankart lesions. Between 2010 and 2014, total 58 patients with anterior shoulder instability due to a Bankart lesion combined with a type II SLAP lesion were enrolled. Patients were divided into two groups: group C consisted of 30 patients, each with a communicated Bankart and type II SLAP lesion and group NC consisted of 28 patients, each with a non-communicated Bankart and type II SLAP lesion. Bankart repairs were performed for all patients. SLAP lesions were repaired in group C and debrided in group NC. Clinical results were analysed to compare groups C and NC by using the visual analogue scale pain score, American Shoulder and Elbow Surgeons score, Constant scores, Rowe score for instability and range of motion assessments. The clinical scores were improved in both groups at final follow-up. Also, there were no differences between two groups. No significant difference was found in terms of the range of motion measured at the last follow-up. The number of suture anchors used was significantly higher in group C than in group NC (5.6 vs. 3.8; <i>p</i>=0.021). In this study, it is considered that Bankart repair and SLAP debridement could be a treatment option in patients with a non-communicated type II SLAP lesion combined with a Bankart lesion (study design: IV, therapeutic study, case series).
