Five articles from the September 2026 issue summarized in five minutes, with the addition of a brief editorial commentary. The 5-in-5 feature is designed to give readers an overview of articles that may pique their interest and encourage more detailed reading. It may also be used by busy readers who would prefer a brief audio summary in order to select the articles they want to read in full. The featured articles this month are: Role of Hypoxia-Inducible Factor–1α in Regulating Muscle Degeneration After Rotator Cuff Tears Selective Epiphysiodesis of the Anterior Distal Femoral Physis Alters Trochlear Morphology in a Rabbit Model Quadriceps Tendon Autografts Are Associated With Increased Short-term Reoperation Rates for Extension Deficit or Pain and Inferior Patient-Reported Outcomes Compared With Hamstring Tendon Autografts: An Analysis of 5653 Cases of Primary Anterior Cruciate Ligament Reconstruction Arthroscopic Correction of Pincer-Type FAI in the Presence of Acetabular Retroversion Results in Excellent Patient-Reported Outcomes With Low Risk of Reoperation or Conversion to Arthroplasty at Minimum 5 Years Length Changes of the Lateral Knee: Fibular Collateral Ligament, Anterolateral Ligament, and Iliotibial Band Fibers Click here to read the articles.

Sex-based disparities in the anterior cruciate ligament (ACL) injury risk may be partly explained by cyclic variations in sex hormones that drive systemic shifts in tissue osmoregulation. Ultrashort echo time (UTE) T2* magnetic resonance imaging provides a noninvasive, quantitative means of evaluating the water content and collagen orientation in tissue.   In conclusion, Eumenorrheic female participants exhibited significant preovulatory to postovulatory changes in ACL T2* metrics, while anovulatory controls demonstrated no significant changes over time. These findings suggest that ACL T2* metrics are sensitive to cyclic fluctuations in female sex hormones across the menstrual cycle.   Click here to read the article.

Long-term studies are emerging reporting encouraging outcomes after matrix-induced autologous chondrocyte implantation (MACI). While MACI has historically been undertaken via open arthrotomy, arthroscopic techniques have been reported. However, longer term clinical outcomes and/or graft survivorship after arthroscopically performed MACI are yet to be reported.   In conclusion, MACI performed via an arthroscopic approach provided sound clinical outcomes, patient satisfaction, and graft survivorship at a mean 13.6 years after surgery.   Click here to read the article.

Join Dr. Miho Tanaka and special guest Dr. Dan Wascher for a timely conversation recorded at the 2026 AOSSM Annual Meeting. In this bonus episode, they discuss Dr. Wascher's recently published article, "Artificial Intelligence Cannot Replace Peer Reviewers but May Help Editors Triage: A Comparative Analysis of a Large Language Model and Human Reviewer Recommendations at the American Journal of Sports Medicine," exploring how large language models (LLMs) may someday support—but not replace—the critical work of human peer reviewers.
