Rotator cuff tendon injuries often lead to shoulder pain and dysfunction. Traditional treatments such as surgery and physical therapy can provide temporary relief, but it is difficult to achieve complete healing of the tendon, mainly because of the limited repair capacity of the tendon cells. Therefore, it is particularly urgent to explore new treatment methods.

Background: Interest in biological augmentation for improving bone-tendon interface (BTI) healing after arthroscopic rotator cuff repair (ARCR) is growing. Dermal fibroblasts, known for collagen synthesis similar to tenocytes, have shown effectiveness in BTI healing in chronic rotator cuff tear (RCT) models in rabbits. However, no human clinical trials have been conducted.

Background: The efficacy of bone marrow aspirate concentrate (BMAC) in promoting bone-tendon interface (BTI) healing without any carriers remains a subject of debate.
Purpose: To evaluate BMAC effects with different carriers on tendon regeneration in a rabbit model of chronic rotator cuff tear.
Study Design: Controlled laboratory study.

Objective: The aim of this study was to examine if tranexamic acid (TXA) can assist in improving outcomes of arthroscopic rotator cu! repair (RCR).
Methods: The databases of PubMed, Embase, Web of Science, CENTRAL, and Scopus were searched for all types of studies examining the e"cacy of TXA for arthroscopic RCR. Twelve studies, 10 randomized controlled trials (RCTs), and 2 retrospective studies were considered eligible.
