Abstract

Background: The purpose of this study was to investigate the relationship between retear after arthroscopic rotator cuff repair and passive range of motion of the shoulder.

Methods: Passive range of motion before and after surgery was compared between the two groups.

Results: The healed and retear groups comprised 86.4% and 13.6% shoulders, respectively. Passive external rotation with the arm at the side at 3 months postoperatively was significantly smaller in the healed group than retear group.

Conclusions: This difference seemed to be associated with stiffness in external rotation of the shoulder and the process of cuff healing after surgery.

Level of evidence: Level III, Case-Control Study, Treatment Study.
