Effect of pectoralis minor relaxation on the prognosis of rotator cuff injury under arthroscopy

Rotator cuff injury is the main cause of shoulder joint pain. Rotator cuff tear is a serious stage of rotator cuff injury. The purpose of this study was to observe the effect of pectoralis minor relaxation on the prognosis of rotator cuff injury under arthroscopy. The clinical data of patients with rotator cuff injury admitted to our department from March 2019 to August 2020 were retrospectively analyzed. These patients were divided into a conventional arthroscopy surgery group and a pectoralis minor relaxation group. The American Shoulder and Elbow Surgeons' Form (ASES) and University of California at Los Angeles Shoulder Scores (UCLASS) were used to assess shoulder joint function during the postoperative and follow-up periods, and the visual analogue scale (VAS) was used to assess shoulder joint pain. Shoulder joint function of the two groups of patients was significantly improved at 1 week postoperatively compared with that before surgery (P
