Abstract

This retrospective study was to demonstrate the clinical outcome of open Bankart repair with suture anchors for recurrent anterior shoulder instability, and to compare surgical results of small (<3 clock units) and large (>3 clock units) Bankart lesions. With an average follow-up of 55.6 months (2–8 years), there were 82 patients (60 right, 22 left shoulders) with the mean age of 27 years accepting open Bankart repair with suture anchors and capsular shift procedure by the same team. According to surgical findings, these patients were grouped into small (<3 clock units) and large (>3 clock units) Bankart lesions. Subjective outcomes were recorded according to the Bankart scoring system of Rowe. Rowe scores averaged 85.9±12.9 (range 25–100). The patients, 92–7 %, had objectively excellent or good results. Twenty nine patients (35.4%) had small Bankart lesions and 53 patients had large Bankart lesions. The Rowe scores in small Bankart lesions were better than that in large Bankart lesions (93.5±6.8 vs.81.8±13.6, Wilcoxon rank sum test, P<0.001). Mean scores of stability (Wilcoxon rank sum test, P=0.043), motion (Wilcoxon rank sum test, P=0.037), and function (Wilcoxon rank sum test, P<0.001) in small lesions also had superior outcomes than in large lesions. Four patients (4.9%) got fair results and two (2.4%) patients got poor results at the end of follow-up. The average loss of external rotation is 10°. Open Bankart repair with the aid of suture anchors still got satisfactory results in the treatment of traumatic recurrent anterior instability of the shoulder. The size of the Bankart lesion was a factor affecting surgical outcome. Small Bankart lesions usually got better results than large Bankart lesions.
