Case: In this case report, we presented the case of an adolescent tennis player with avulsion injury of the subscapularis tendon of the right shoulder.
Patients: A 17-year-old right-hand-dominant male tennis player visited our hospital complaining of pain in the anterior aspect of the right shoulder. We performed X-ray and three-dimensional computed tomography (3D-CT) and magnetic resonance imaging (MRI) scans for the diagnosis.
Results: Plain radiographs did not reveal the presence of lesion; however, 3D-CT and MRI scans showed a small bony fragment located between the humeral head and the glenoid of the scapula and a high-intensity area of the subscapularis tendon. He was subsequently diagnosed with incomplete joint side tear of the subscapularis tendon with a small bony fragment. Subsequently, we performed arthroscopic excision of the bony fragment and repair of the subscapularis tendon.
Conclusions: This case highlighted the presence of an injury with minor trauma associated with repeated tennis strokes in a skeletally immature patient.

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.

Purpose: This study aimed to compare clinical outcomes between open and arthroscopic anterior latissimus dorsi (LD) transfer techniques for treating irreparable subscapularis (SSC) tears.
Methods: We retrospectively reviewed patients who underwent open or arthroscopic anterior LD transfer for irreparable SSC tears between February 2014 and August 2020. Patients were included if they had irreparable SSC tears with Lafosse Grade 4 or higher and Goutallier Grade 3 or higher, but without advanced arthritis (Hamada Grade < 3).

Background: This study aimed to evaluate how subscapularis tendon repair influences joint loads in relation to humeral offset and arm position.
Patients And Methods: Two fresh-frozen, whole-body cadaveric shoulders underwent a reverse total shoulder arthroplasty (rTSA) on the humeral side using an internal proprietary load-sensing system (LSS) (Goldilocks, Statera Medical, Montreal, Canada). In addition to three "complex" Activity Daily Life positions ("behind the back", "overhead reach", and "across the chest"), four standard postures (external rotation, extension, abduction, and flexion) were used to record the glenohumeral loads (Newtons) and their locations applied to the implant.

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.

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.
