Assessment of the Postoperative Appearance of the Rotator Cuff Tendon Using Serial Sonography After Arthroscopic Repair of a Rotator Cuff Tear



Assessment of the Postoperative Appearance of the Rotator Cuff Tendon Using Serial Sonography After Arthroscopic Repair of a Rotator Cuff Tear



Journal of Ultrasound in Medicine 34(7): 1183-1190



The purpose of this study was to evaluate serial changes in sonographic findings of a rotator cuff tendon after rotator cuff repair. Sixty-five arthroscopically repaired rotator cuff tears (43 full-thickness tears and 22 partial-thickness tears) were retrospectively included in this study. Serial sonographic examinations were performed at 5 weeks, 3 months, and 6 months after surgery. The sonographic findings of the repaired tendon were assessed for a recurrent tear, tendon thickness, morphologic tendon characteristics, vascularity, and bursitis at each time point. Four recurrent tears occurred within 3 months of surgery. The postoperative tendon thickness decreased from 5 weeks to 6 months after surgery (P = .001). There were significant changes in the morphologic tendon characteristics, including the echo texture, fibrillar pattern, and surface irregularity of the repaired tendon, from 5 weeks to 6 months after surgery (P < .001). Additionally, subacromial-subdeltoid bursitis and the vascularity of the repaired tendon decreased postoperatively over time. Serial sonography after arthroscopic rotator cuff repair was useful for monitoring the postoperative changes in a repaired tendon. The morphologic appearance of the repaired tendon and peritendinous soft tissue changes improved over time and nearly normalized within 6 months of surgery.
