Purpose
The purpose of this study was to compare the clinical results of isolated arthroscopic Bankart repair and those of arthroscopic Bankart repair with posterior capsulodesis for anterior shoulder instability with engaging Hill–Sachs lesions.
Methods
Thirty-five shoulders that underwent isolated arthroscopic Bankart repair (Bankart group) and 37 shoulders that underwent arthroscopic Bankart repair with posterior capsulodesis (remplissage group) for anterior shoulder instability with engaging Hill–Sachs lesions were evaluated retrospectively. The mean age at the time of the surgery was 26.1 ± 7.0 years in the Bankart group and 24.8 ± 9.0 years in the remplissage group.
Results
At the final follow-up, the Rowe and UCLA scores significantly improved in both the Bankart and remplissage groups (P < 0.001, in both groups). The post-operative mean deficit in external rotation at the side was 3° ± 10° in the Bankart group and 8° ± 23° in the remplissage group (P = n.s. and P = 0.044, respectively). There was no decrease in muscle strength in either group. The recurrence rate was 25.7 % in the Bankart group and 5.4 % in the remplissage group (P = 0.022).
Conclusions
Arthroscopic Bankart repair with posterior capsulodesis demonstrated good clinical outcomes with a low recurrence rate in the treatment for anterior shoulder instability with an engaging Hill–Sachs lesion. Although a limitation in external rotation was observed, there was no significant limitation of any other motion and no decrease in muscle strength after the remplissage procedure. Posterior capsulodesis alone for remplissage should be considered as a surgical technique that can replace the conventional method.
