Article Abstract
Purpose: The aim of this study was to investigate how the critical shoulder angle (CSA) and acromion index (AI) affect the outcome of arthroscopic rotator cuff tear (RCT) repair.
Methods: A total of 287 patients, who underwent arthroscopic surgery due to degenerative rotator cuff tear, were evaluated. The Constant Shoulder Score (CSS), Oxford Shoulder Score (OSS) and Visual Analogue Scale (VAS) were evaluated preoperatively and postoperatively. The AI and CSA were measured on true anteroposterior shoulder radiographs. The patients were separated into two groups according to their CSA and AI values (control group ≤ 38°, increased CSA > 38°, and control group ≤ 0.7, increased AI > 0.7). The relationship between CSS, OSS and VAS was examined in all the groups.
Result: The evaluation was made of a total of 287 patients with a mean age of 60.29 ± 8.55 years. The mean duration of follow-up of the patients was 34.00 ± 18.97 months (range 12-80 months). There was a statistically significant difference between the preoperative and postoperative clinical scores of the patients (< 0.05). No relationship was determined between CSA, AI and CSS, OSS or VAS during follow-up (> 0.05). The interobserver ICC for CSA and AI were determined to be 0.962 and 0.967, respectively (95% CI) indicating a high correlation (< 0.001).
Conclusion: CSA and AI do not affect functional outcomes in the postoperative period, so they are not significant at the time of degenerative arthroscopic rotator cuff repair decisions.

Introduction: Reverse total shoulder arthroplasty is a well-established treatment for patients with rotator cuff tear arthropathy. The outcome after reverse total shoulder arthroplasty has been investigated in several studies and national registries. However, the treatment has not been compared to non-surgical treatment.

Rotator cuff tendinopathy is a common cause of shoulder pain and dysfunction, presenting in two primary forms: calcific and non-calcific. These subtypes differ significantly in their pathophysiology, clinical manifestations, and natural history, necessitating tailored diagnostic and therapeutic approaches. This review delineates the clinical presentations of calcific rotator cuff tendinopathy (RCCT), characterized by distinct pre-calcific, calcific, and post-calcific stages, and contrasts them with the more insidious, degenerative course of non-calcific rotator cuff tendinopathy.

Methods: This systematic review was conducted in accordance to PRISMA guidelines and was registered in PROSPERO (CRD4202461663). A comprehensive search was done in the following databases MEDLINE, Web of Science, Google Scholar.
Repair of rotator cuff injuries using transosseous tunnels. Introduction to the technique, devices and other relevant points.

Rotator cuff injuries are common and procedures of repair have evolved from open techniques to minimally invasive and arthroscopic ones. Despite these advances, the biomechanics, biology, and value of transosseous repairs remain superior, leading to the development of innovative devices that enable the utilization of this technique without the use of anchors, improving both the efficiency and safety of the procedure. This article reviews the latest advances in transosseous rotator cuff repair, highlighting its biomechanical advantages, as well as the factors that enhance recovery and offer more consistent long-term outcomes.

The rupture of the teres major muscle is a well-known condition in sports activities like baseball, hockey, and tennis. There is no real consensus in the literature regarding treatment, with approaches varying between functional and surgical methods. While functional treatment appears to be a viable option, there is a lack of evidence indicating significant improvement in medial rotation strength after aforementioned treatment.
