: Arthroscopic rotator cuff repair faces high retear risks in multi-tendon injuries due to insufficient biological healing; leukocyte-rich PRP may enhance tendon-bone integration through inflammatory modulation and growth factor release. : Four databases including PubMed, Embase, Cochrane Library, and Web of Science were searched until March 2025. Literature screening, quality evaluation, and data extraction were performed according to inclusion and exclusion criteria. GRADE was used to grade the strength of the evidence and the results. : The main finding of this study was that leukocyte-rich platelet-rich plasma combined with arthroscopic surgery for rotator cuff injuries can improve the Constant Score (MD = 1.13, 95% CI: 0.19, 2.07, = 0.02, I = 47%), American Shoulder and Elbow Surgeons score (MD = 6.02, 95% CI: 4.67, 7.36, < 0.01, I = 0%), and University of California, Los Angeles score (MD = 1.20, 95% CI: 0.34, 2.06, < 0.01, I = 0%) of patients with rotator cuff tear after treatment, and reduce the postoperative Visual Analog Scale score (MD = -0.62, 95% CI: -1.16, -0.08, = 0.02, I = 83%) of patients. However, there were no statistical differences regarding the Simple Shoulder Test (MD = 0.08, 95% CI: -0.23, 0.39, = 0.61, I = 5%). : Based on current evidence, the use of LR-PRP in arthroscopic rotator cuff repair could lessen postoperative pain and improve postoperative functional scores in individuals with rotator cuff injuries.

Introduction: During the healing process, the functional gradient attachment of the rotator cuff (RC) tendon-bone interface fails to regenerate, which severely impedes load transfer and stress dissipation, thereby increasing the risk of retears. As a result, the treatment of rotator cuff tears remains a significant clinical challenge.
Methods: In this study, a dual-crosslinked hyaluronic acid/polyethylene glycol (HA/PEG) hydrogel scaffold was synthesized using hyaluronic acid and polyethylene glycol as base materials.

The clinical presentation of rotator cuff ruptures varies greatly and ranges from no symptoms to severe shoulder impairment. Clinical shoulder tests are an effective screening tool to identify patients who require early specialist assessment or further radiological investigation, but they are not sufficient to rule out smaller ruptures. Small ruptures can often be managed non-surgically, while larger traumatic ruptures may necessitate early surgical intervention.

Introduction/objectives: Irreparable subscapularis tears can cause severe functional impairment and present significant clinical challenges. Current treatment options include tendon transfers (TTs), anterior capsular reconstruction, and reverse shoulder arthroplasty. Each approach has distinct biomechanical advantages and limitations, but there remains no consensus regarding the optimal treatment.

Introduction: Accurate diagnosis of subscapularis tears remains challenging due to the limitations of physical examinations and imaging techniques. Therefore, specific radiological parameters have been proposed as predictors of atraumatic subscapularis tears to improve diagnostic sensitivity and accuracy. These parameters include coracohumeral distance (CHD), coracoglenoid angle (CGA), coracoid angle (CA), coracoid overlap (CO), and coracohumeral angle (CHA).

Purpose: The aim of this study was to evaluate the radiological-functional outcomes and rotator cuff (RC) status following humeral intramedullary nailing (IMN), comparing the anterolateral standard approach (group 1) and the percutaneous antero-acromial approach (group 2).
Methods: This observational prospective monocentric study was conducted from August 2021 to March 2023. Inclusion criteria included: two-parts proximal (surgical neck) and diaphyseal Humeral fractures treated with IMN; 12-month follow-up; age between 18 and 85 years; good performance status (excluding neurologic deficits or mental disorders).
