Rotator cuff injury is the most common clinical shoulder joint disease, accounting for 50%-85% of all shoulder joint diseases. At present, arthroscopic rotator cuff repair has replaced the traditional surgical plan of incision and suture, becoming the first choice of surgeons. Its effectiveness and safety have been recognized in the industry. However, there are also occasional cases with poor postoperative effects and insufficient pain relief.

To analyze the prognostic factors of arthroscopy rotator cuff repair.

From February 2019 to February 2020, the primary data of 117 patients who received arthroscopic rotator cuff repair in the department of orthopedics of tenth people's hospital of Tongji university were retrospectively analyzed, and the surgical efficacy was followed up for one year after surgery.

There were 95 patients with a good prognosis, accounting for 81.20%. Multivariate analysis showed that age, preoperative course of the disease, degree of tear, and the use of platelet-rich plasma (PRP) were independent factors affecting prognosis.

The age, preoperative course of the disease, rotator cuff tear degree, use of PRP during operation are important factors affecting the prognosis of arthroscopy rotator cuff repair.
