[Research progress on factors of shoulder stiffness after rotator cuff tear repair].

Rotator cuff tear is a common shoulder injury in daily work and sports activities. Arthroscopic repair is the most widely used method for rotator cuff tears, and the postoperative prognosis is good. However, there are still a series of postoperative complications that affect the therapeutic effect and patient satisfaction, such as postoperative pain, infection, retear, shoulder stiffness, etc.

Delamination of rotator cuff tears impairs healing after repair: a systematic review and meta-analysis.

Purpose: To compare the clinical outcomes and retear rates after rotator cuff repair (RCR) between delaminated and non-delaminated tears.

Methods: This systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses guidelines using the PubMed, Cochrane Library, the Web of Science and Embase databases. Only articles on arthroscopic RCR with clinical outcome scores and data on the number of rotator cuff retears and complete healing were included.

Association of obesity with high retears and complication rates, and low functional scores after rotator cuff repair: a systematic review and meta-analysis.

Background: Obesity influences the outcomes of orthopedic surgeries such as total knee arthroplasty and spinal surgery. However, the effect of obesity on the outcomes of rotator cuff repair is unknown. This systematic review and meta-analysis aimed to examine the effect of obesity on rotator cuff repair outcomes.
