The purpose of this study was to clarify the clinical outcomes and problems of arthroscopic rotator cuff repair (ARCR) in patients 65-years of age and older. We evaluated the clinical results and repair integrity using MRI in 42 patients with ARCR (18 men and 24 women, mean age at the time of surgery 70.3 years old). Preoperatively and at the time of follow-up (at a mean of 19.1 months), the patients were assessed with Japanese Orthopaedic Association (JOA) shoulder scores. Subjective symptoms and JOA shoulder scores of all patients improved after surgery (p<0.0001). The average postoperative JOA shoulder score at 12 months after surgery improved to 96.5 (vs.51.5 preoperatively) points. An average postoperative abduction range improved to 170°(preoperatively 94° ), and external rotation improved to 61° (preoperatively 20° ). Postoperative complications including CRPS, shoulder stiffness and anchor failure were not seen in this series. No differences were observed in clinical outcomes compared with 24 shoulders in patients 65-years of age and younger. MRI examinations 6months postoperatively showed high intensity in the repaired cuff in 9 of 18 shoulders that had had large and massive tears, whereas small and medium tears presented good repair integrity in 88% (21 of 24 shoulders).
