- - The review focuses on functional metrics and patient-reported outcome measures (PROMs) used to evaluate when athletes can safely return to their sport after reconstructive surgery for an anterior cruciate ligament (ACL) injury.
- - The limb symmetry index (LSI) is the key functional metric, with a value of 90% or higher compared to the other leg indicating readiness to return, while other measures like ACL-RSI, IKDC, and KOOS-QoL also provide important insights.
- - There is a need for more research on the impact of sex, competition level, and accompanying injuries on return-to-sport rates and injury recurrence, to identify which measures effectively predict successful outcomes after ACLR.
Article Synopsis
- Platelet-rich plasma and hyaluronic acid show promise as low-risk treatments for Achilles tendinopathy, but research findings are inconsistent and study quality is often questionable.
- Other treatments like bone marrow aspirate and stem cells have reported benefits, but there is a lack of strong evidence from high-level studies.
- The use of exosomes presents an exciting new area of research due to their potential to enhance tendon health, but future studies must standardize methods for better evaluation of these therapies.
The popularity of pickleball has rapidly increased in the United States, with over 48 million adult participants in recent years, leading to a growing need to better understand injuries exclusive to pickleball. Pickleball-related injuries are predominantly musculoskeletal, most commonly sprains and strains to the upper and lower extremities. Sport-specific variables, including sporting equipment, playing conditions, and proper technique may be utilized to guide clinicians in injury management and preventative treatment.

Purpose: To systematically review the contemporary literature and evaluate patient-reported outcome measures (PROMs), functional knee measures, and the incidence of complications in patients aged 50 years and older undergoing anterior cruciate ligament reconstruction (ACLR) at short- to mid-term follow-up.
Methods: A literature search was conducted across the PubMed, Embase, and Scopus databases, spanning from database inception to November 2023, in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The inclusion criteria consisted of clinical studies reporting PROMs, measures of knee stability, and complication rates after ACLR in patients aged 50 years and older with minimum 2-year follow-up.
Article Synopsis
- A systematic review and meta-analysis evaluated the effects of blood flow restriction (BFR) training compared to non-BFR rehabilitation following anterior cruciate ligament reconstruction (ACLR).
- Eight randomized controlled trials with a total of 245 patients were included, showing that BFR training primarily improved pain levels, muscle strength, and knee function scores.
- Although BFR was effective in enhancing certain clinical outcomes, it did not have a significant impact on increasing quadriceps muscle volume post-rehabilitation.
Purpose: To investigate the accuracy of Chat Generative Pre-Trained Transformer (ChatGPT)'s responses to frequently asked questions prior to rotator cuff repair surgery.
Methods: The 10 most common frequently asked questions related to rotator cuff repair were compiled from 4 institution websites. Questions were then input into ChatGPT-3.
Purpose: To identify the risk of anterior cruciate ligament (ACL) injury in adolescent athletes based on sex, sport, and sport affiliation.
Methods: A literature search was performed using 3 online databases (PubMed, Cochrane Library, and EMBASE) from database inception to November 2023 per the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies consisted of Level I or II studies reporting on ACL injury exposures in time (hours) or injuries per 1,000 athlete-exposures (AEs) (1 game or practice) in adolescent athletes.
Anterior cruciate ligament (ACL) injuries in young, active patients generally require ACL reconstruction (ACLR) to restore mechanical and postural stability. The fear of movement or reinjury (kinesiophobia) has become increasingly recognized in the post-ACLR population; however, the association between restoration of postural stability and kinesiophobia remains largely unknown. The purpose of this study was to investigate changes in mean Tampa Scale of Kinesiophobia-11 (TSK-11), dynamic motion analysis (DMA) scores, and time on the testing platform, as well as any correlation between TSK-11 and mean overall and individual translational and rotational DMA scores during the first 12 months following ACLR.

- Isolated injuries to the proximal tibiofibular joint are rare but often occur in young athletes engaged in high-impact sports, particularly those involving explosive movements and hyperflexed knees.
- This joint's stability relies on various structures, with the anterior complex offering the most support, and injuries typically result in the fibula displacing anteriorly and laterally from its joint with the tibia.
- Accurate diagnosis through thorough history and physical examination is critical, as missed injuries may lead to ongoing pain and disability; treatment can vary from spontaneous reduction to surgical stabilization.
