We conducted clinical evaluation and image assessment of the LHB patching procedure for examination of its clinical performance in rotator cuff tear cases including the subscapular tendon tear. Rotator cuff tear cases with more than a large tear and which were followed-up for more than 2 years after operation were divided into 2 groups: 75 cases in which LHB patching procedure was combined with the McLaughlin's procedure (LHB Group) and 82 cases in which only McLaughlin's procedure was used (Control Group). We compared the 2 groups in terms of joint range of motion (ROM), muscle strength, UCLA score, and image assessments of tendon attachment using MRI and US before operation and at 6 months, 1 year, and 2 years after. ROM and image assessments showed no significant difference. In terms of muscle strength, abduction 6 months after the operation and flection and abduction 1 year after the operation in the LHB Group were significantly smaller than those in the Control Group (p<0.05). In terms of the UCLA score, the total score 2 years after the operation did not show statistically significant between the LHB Group (32.6±2.6) and Control Group (33.1±2.2). However, satisfaction of the patient at 6 months, 1 year, and 2 years after the operation in the LHB Group was significantly lower than those in the Control Group (p<0.05). The LHB patch method demonstrated good clinical results and good recovery of the tendon attachment 2 years after the operation. However, the patient's satisfaction was significantly lower at all times after the operation, because of delayed improvement of muscle strength.
