Rotator cuff tears (RCTs) are common in shoulder disease and disability. Despite significant advances in surgical repair techniques, 20-70% of patients still have postoperative rotator cuff dysfunction. These functional defects may be related to retear or rotator cuff quality deterioration due to tendon retraction and scar tissue at the repair site. As an effective delivery system, hydrogel scaffolds may improve the healing of RCTs and be a useful treatment for irreparable rotator cuff injuries. Although many studies have tested this hypothesis, most are limited to laboratory animal experiments. This review summarizes differences in hydrogel scaffold construction, active ingredients, and application methods in recent research. Efforts to determine the indications of hydrogel scaffolds (with different constructions and cargos) for various types of RCTs, as well as the effectiveness and reliability of application methods and devices, are also discussed.

Effectiveness of high intensity laser treatment in partial supraspinatus tendon tears: a randomised controlled trial.
Lasers Med Sci
January 2025
Ankara Bilkent City Hospital Physical Therapy and Rehabilitation Hospital, Department of Physical Medicine and Rehabilitation, Ankara, Türkiye.
The most common cause of rotator cuff injury is supraspinatus tendon tears (STTs). High-intensity laser therapy (HILT) has recently emerged as an important conservative treatment option. This study was designed as a randomised controlled trial in patients with partial STTs to compare the effects of HILT with those of ultrasound (US) therapy.

Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Carthage Area Hospital, Carthage, New York, USA.
Background: While glenoid bone loss (GBL) after anterior shoulder instability correlates with poor functional outcomes, the specific effects of GBL in posterior and combined-type shoulder instability remain poorly characterized, especially in a high-risk military population.
Purpose/hypothesis: The purpose of this study was to compare GBL between unidirectional anterior or posterior instability versus combined-type instability in active-duty servicemembers. It was hypothesized that total GBL and GBL in the direction of instability would be greater in those with combined-type instability compared with unidirectional instability.
Association Between Rotator Cuff Tears and Shoulder MRI Parameters: Importance of Arthroscopic Validation in Coronal Acromiohumeral Interval Measurement.
Orthop J Sports Med
January 2025
Department of Orthopaedics and Traumatology, Faculty of Medicine, Tınaztepe University, Izmir, Turkey.
Background: Magnetic resonance imaging (MRI) measurement parameters-the standard noninvasive diagnostic method for rotator cuff tears (RCTs)-have been used to compare groups with and without RCTs. Arthroscopy is used in definitive diagnosis and treatment.
Purposes: To evaluate the association between RCT and shoulder angles and distances on MRI in patients with and without arthroscopically validated RCT and to determine whether the degree of rotator cuff fatty degeneration affects the MRI measurements.
Hierarchy Reproduction: Multiphasic Strategies for Tendon/Ligament-Bone Junction Repair.
Biomater Res

Academy of Orthopedics, Guangdong Province, Orthopedic Hospital of Guangdong Province, The Third Affiliated Hospital of Southern Medical University, Guangzhou 510665, P. R. China.
Tendon/ligament-bone junctions (T/LBJs) are susceptible to damage during exercise, resulting in anterior cruciate ligament rupture or rotator cuff tear; however, their intricate hierarchical structure hinders self-regeneration. Multiphasic strategies have been explored to fuel heterogeneous tissue regeneration and integration. This review summarizes current multiphasic approaches for rejuvenating functional gradients in T/LBJ healing.

Department of Rehabilitation Sciences, Faculty of Medicine and Health Sciences, Ghent University, Campus UZ Gent, Ghent, Belgium.
Background: Reversed shoulder arthroplasty (rTSA) is often used to restore functionality in patients with joint arthropathy and dysfunctional rotator cuff. As rTSA changes the biomechanical properties of the shoulder, an altered movement pattern of arm and scapula is to be expected. Previous studies focused on changes of the scapulohumeral rhythm during functional elevation tasks.
