Abstract:

Objective Toobserve the clinical efficacy of arthroscopic superior fulcrum reconstruction versus superior capsule reconstruction in the treatment of irreparable massive rotator cuff tears， in order to provide more therapeutic choices. Methods A total of 28 patients with irreparable massive rotator cuff tears， who had been admitted to the Department of Orthopedics， the Third Affiliated Hospital of Anhui Medical University from September 2021 to July 2023 were selected， 14 of whom underwent arthroscopic superior fulcrum reconstruction（superior fulcrum reconstruction group）and 14 underwent arthroscopic superior capsule reconstruction（superior capsule reconstruction group）. The observation indexes were operative time， intraoperative blood loss， shoulder joint active range of motion， the university of California at Los Angeles shoulder rating scale（UCLA）， American Shoulder and Elbow Surgeons′ score （ASES）， the shoulder score of Constant-Murley（CMS） and Visual Analogue Scale （VAS）. Results All patients had a successful surgery and a postoperative follow-up was at least 12 months. The postoperative shoulder joint active range of motion， UCLA， ASES and CMS between the two groups， which were statistically significant （P < 0.05）， superior fulcrum reconstruction group was better than superior capsule reconstruction group. There was no significant difference in postoperative VAS， operative time or intraoperative blood loss between the two groups （P > 0.05）. Conclusions Arthroscopic superior fulcrum reconstruction outperforms superior capsule reconstruction in the treatment of irreparable massive rotator cuff tears.
