Introduction And Objectives: Rotator cuff re-ruptures appear in 38-65% of cases. In order to reduce this rate, many studies have been performed using different types of biomaterial for purely mechanical aims (re-inforce the suture) and/or biological agents (growth factor transporterts). The aim of this study is to review 22 cases treated with xenografts and analyse various current alternatives.
Materials And Methods: A descriptive and retrospective study was conducted using the variables of age, sex, laterality, time of surgery, involvement in MRI, number of anchors, and final mobility results on the Constant and the University of California Los Angeles (UCLA) validated scales.
Results: The study included 22 patients, with a mean age of 51.7±4.6 years. A mean of 2 anchors were used and 13 patients were treated with a porcine intestinal submucosa implant, 6 with equine pericardium, and 3 with porcine dermis. Final results were: 37.6±13 points for the Constant test, and 16.9±3.9 points on the UCLA scale. The follow up was 36±10.2 months.
Conclusions: In our experience, xenografts could provide good functional results and they would be a surgical alternative to tendon transfers in cases of massive tears. Further studies should be conducted with other biomaterials.

Background: The challenge of achieving effective tendon-to-bone healing remains a significant concern in sports medicine, necessitating further exploration. Biomimetic electrospun nanomaterials present promising avenues for improving this critical healing process.
Purpose: To investigate the biological efficacy of a novel aligned-to-random PLGA/Col1-PLGA/nHA bilayer electrospun nanofiber membrane in facilitating tendon-to-bone healing.

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.

Background: The importance of the subscapularis for reverse total shoulder arthroplasty has been demonstrated, especially for internal rotation and stability. In a deltopectoral approach, a detachment of the subscapularis is performed (tenotomy, tuberosity peeling, or osteotomy), but the tendon is not always repairable at the end. When it is repaired, healing is obtained in only 40%-76% of the cases, with potential consequences for the outcomes.
