Summary: In soccer, dominant limb kicking results in higher ball velocity and frequency, with a higher risk of injury to the dominant limb, particularly in hamstring and hip/groin areas. This increased risk is consistent across playing levels, genders, and age groups, highlighting the importance of considering limb dominance in soccer injury studies.

Summary: This study aimed to establish consensus statements on the Latarjet procedure, remplissage, and glenoid-bone grafting for anterior shoulder instability. A modified Delphi process was used with the participation of 65 shoulder surgeons from 14 countries. The results showed that a subscapularis split approach should be utilized for the Latarjet procedure and glenoid bone-graft, and the need for capsular repair with a glenoid bone graft was unclear. Remplissage procedure was indicated for off-track or engaging Hill-Sachs lesion without severe glenoid bone loss.

Summary: This study aimed to establish consensus on revision surgery, rehabilitation, and follow-up for anterior shoulder instability. The primary indications for revision surgery include symptomatic apprehension or recurrent instability, additional intra-articular pathologies, and symptomatic hardware failure. The minimum time for athletes to return to play is unknown, but factors such as strength, range of motion, and resolved pain should be considered. Psychological factors should also be taken into account during rehabilitation. Clinical follow-up should be conducted for at least 12 months or until a return to full function.

Summary: This study compared the transcriptome profile of articular cartilage in early stage hip impingement to advanced hip osteoarthritis (OA) secondary to impingement, and investigated the expression of DNA methylation enzymes and peroxisome proliferator-activated receptor gamma (PPAR gamma) during hip OA progression. The study identified distinct transcriptome profiles and key molecular contributors to the progression of hip OA. Preserving endogenous PPAR gamma may have therapeutic potential for delaying or preventing hip OA.

Summary: Previous studies have shown that psychosocial factors and comorbid depression affect preoperative symptoms in patients undergoing shoulder surgery. This study aimed to determine if these factors have a different impact on patients with traumatic vs. atraumatic shoulder instability. The results indicate that worse psychosocial factors are more strongly associated with shoulder-related pain and function in patients with atraumatic instability.

Summary: This study examined the catabolic state of articular chondrocytes and the expression of DNMT3B and ABAT during the progression of osteoarthritis (OA) in hip femoroacetabular impingement (FAI). The findings showed that early-FAI and late-FAI-OA patients exhibited a histological OA phenotype and increased expression of catabolic markers. DNMT3B was underexpressed and ABAT was overexpressed in advanced disease. IL1 beta stimulus further accentuated catabolic marker overexpression through ABAT promoter hypomethylation, while TGF beta normalized these alterations. Suppression of ABAT through methylation control could be a potential therapeutic target for preventing OA progression in hip FAI.

Summary: This study aims to evaluate the validity and responsiveness of a shortened version of the Western Ontario Shoulder Instability Index (Short-WOSI) compared to the full WOSI and other shoulder-related PROM instruments. The results show that the Short-WOSI demonstrates excellent internal consistency, good construct validity, and similar responsiveness to the full WOSI over time. Neither the Short-WOSI nor the WOSI correlates well with more general shoulder PROMs, highlighting the advantage of using instability-specific instruments for this population.
