One-stage surgical treatment for concomitant rotator cuff tears with shoulder stiffness has comparable results with isolated rotator cuff tears: a systematic review.

Addressing preoperative shoulder stiffness before rotator cuff repair (RCR) is advocated, but the effectiveness of this approach is debatable. We hypothesized that 1-stage treatment of concomitant rotator cuff tear (RCT) with shoulder stiffness has comparable results with isolated RCT.
