Background: This study was undertaken to clarify the usefulness and problems of the procedure comprising mini-open repair and long head of biceps tendon (LHB) anchoring in the treatment of rotator cuff tears with subscapularis tendon tears.
Methods: Ninety-eight shoulders that had been treated with these procedures at least 2 years before (group SSC) were subjected to this study. A control group consisted of 368 shoulders, which had been treated using the mini-open repair technique alone. The two groups were assessed comparatively with respect to medical history, range of motion (ROM), muscle strength, UCLA score, and MRI findings.
Results: Preoperatively, only flexion angles of the group SSC were significantly smaller than those of the control group (p < 0.01). At 2 years postoperatively, abductor muscle strength was significantly lower in group SSC than in the control group (p < 0.05). UCLA shoulder rating scores at 2 years postoperatively were good results or better in 91% of group SSC patients, yet with significantly lower degree of patient satisfaction and lower total scores, compared to the control group (p < 0.05 and p < 0.05, respectively). MRI scans at 2 years postoperatively showed high-intensity areas at the insertion of the supraspinatus muscle in 23% of group SSC patients, and this percentage was significantly higher than that in the control group (p < 0.01).
Conclusion: The clinical results at 2 years postoperatively were remarkably satisfactory with the combined procedures, but the present data seem to indicate that there still remains room for further procedural improvement.
