Risk Factors for Shoulder Stiffness After Rotator Cuff Repair: A Systematic Review and Meta-analysis

This study revealed a pooled incidence of 12.9% for stiffness after RCR, with notable variations observed across diagnostic criteria and follow-up durations. Additionally, older age, diabetes, fatty infiltration, and concomitant subacromial decompression were identified as significant risk factors for postoperative stiffness. Clinicians should prioritize recognizing these risk factors and implementing evidence-based preventive strategies to reduce the incidence of stiffness after RCR.
