Prospective evaluation of arthroscopic rotator cuff repairs at 5 years: part II–prognostic factors for clinical and radiographic outcomes

Background tor cuff registry was established to prospectively evaluate the effectiveness of all-arthroscopic repairs. The purpose of this study is to report prognostic factors for successful clinical and radiographic outcomes at 5 years. s ndred ninety-three patients underwent all-arthroscopic rotator cuff repairs. Pre- and intraoperative data were compared to the American Shoulder and Elbow Surgeon (ASES) score, range of motion, muscle strength, and ultrasound results at 5 years using univariate, and multivariate analyses. s ears, 106 patients completed follow-up. There were no pre- or intraoperative variables that were predictive of an ASES score >90. Factors predictive of a radiographic defect were larger size of the lesion (OR 1.72, 95% CI 1.04-2.85, P = .03), multiple tendon involvement (OR 5.56, 95% CI 1.23-25.22, P = .02), older age (OR 1.15, 95% CI 1.04-1.28, P = .01), concomitant biceps (OR 16.16, 95% CI 3.01-86.65, P = .001), and acromioclavicular joint procedures (OR 6.70, 95% CI 1.46-30.73, P = .01). Radiographic healing did not correspond to clinical outcomes. Resolution of a radiographic defect was seen in 14 patients. Younger age (OR 0.84, 95% CI 0.74-0.95, P = .004) and single-tendon tears (OR 7.59, 95% CI 1.71-84.45, P = .04) were predictive. sion tears in older patients who undergo concomitant procedures are predictive of radiographic defects at 5 years; however, radiographic healing did not correspond to clinical results. Younger patients with single tendon tears are more likely to undergo spontaneous resolution of a radiographic defect. This information can be useful in counseling patients regarding the mid-term results of this procedure.
