Prospective evaluation of clinical and radiologic factors predicting return to activity within 6 months after arthroscopic rotator cuff repair

BACKGROUND: This study aimed to report the outcome of patients who underwent arthroscopic rotator cuff repair (ARCR) and to determine the factors associated with return to work and activity.
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 return 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 associated with being in group B. Lack of tendon healing was not associated with group B. However, if a patient 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.
