We investigated the postoperative condition of patients who underwent surgery for rotator cuff tears using sonography. The sonographic findings displayed an unclear superficial layer during working pain caused by rotator cuff dysfunction.As a method of improving this pain, we devised rotator cuff exercises for patients to do with a direct monitor.We reviewed the reduction of postoperative pain due to these exercises. We surgically treated 76 shoulders in 75 patients with rotator cuff tears that displayed an unclear superficial layer on sonographic findings. The patients were divided into 2 groups: a non-exercise group (29 shoulders) and an exercise group (47 shoulders).There were no significant differences between the groups in patient characteristics for gender, cuff tear size, or age.We evaluated the clinical results based on the Japanese Orthopaedic Association (JOA) score. The JOA pain score for the exercise group was significantly higher at 12 months than at 6 months, but was not significantly different in the non-exercise group. In this study, patients with postoperative rotator cuff pain were able to significantly reduce their pain by doing visual feed-back rotator cuff exercises using sonography.We believe that this is an effective method of renewing rotator cuff function.
