Materials: Three hundred sixty-five patients who underwent ARCR were prospectively evaluated. The cohort was divided into 2 groups based on clinical results at 6 months. Group A consisted of patients who were considered to have a satisfactory outcome based on return to their previous professional or spare-time activities. Group B consisted of patients with an unsatisfactory outcome based on a lack of re- turn to normal work or activities. Results: Of the patients, 305 had a satisfactory outcome (group A) and 60 were categorized as having an unsatisfactory outcome (group B). On multivariate analysis, preoperative factors associated with group B included female gender and heavy manual labor. Postoperative bursitis on ultrasound at 6 months was asso- ciated with being in group B. Lack of tendon healing was not associated with group B. However, if a pa- tient without healing had persistent pain at 6 months, the pain persisted at 9 months. Conclusion: ARCR is an effective procedure that leads to significant improvement in pain, function, and tendon healing in most cases. However, in 1 of 5 cases, patients were unable to resume normal activity at 6 months postoperatively. Persistent limitation at 6 months was associated with female gender, heavy manual workers, and the presence of postoperative persistent bursitis.
