Bankart repair with subscapularis augmentation: A case control study

Abstract

To examine the effect on functional shoulder scores of Bankart repair with arthroscopic subscapularis tendon augmentation applied to cases of anterior shoulder instability with < 25% glenoid defect and ligament-labral failure. A total of 83 patients underwent Bankart repair with subscapularis tendon augmentation between 2015 and 2021. The range of movement of the patients was measured by 2 doctors using a goniometer. The Constant Murley score, American Shoulder and Elbow Surgeons score, Rowe score, and the University of California at Los Angeles scores were recorded preoperatively and postoperatively. Statistically significant increases were determined in the postoperative functional scores compared to the preoperative values as mean 41.4 ± 2.08 unit increase in the Constant Murley score, mean 41.4 ± 1.8 unit increase in the American Shoulder and Elbow Surgeons score, mean 13.8 ± 1.45 unit increase in the University of California at Los Angeles and mean 49.3 ± 7.45 unit increase in the Rowe score (P = .001; P < .01). Compared with the preoperative evaluation, there was found to be a postoperative statistically significant unit decrease of 10.2 ± 1.47 in the external rotation measurement (P = .001; P < .01). The number of dislocations was determined to have a negative correlation with the internal rotation measurements (r = −0.305; P = .005; P < .01), and a weak negative statistically significant relationship with external rotation measurements (r = −0.329; P = .002; P < .01). Unlike other techniques, as this repair technique includes both the tendon and the capsule as a single piece, it was seen to be a sufficient and reliable technique that is easy-to apply.
