- Comparable Midterm Survival After Medial Meniscus Root Repair for High and Low Intraoperative Outerbridge Classification Grades. [Journal Article]Am J Sports Med. 2026 Jul 14; :3635465261460747. [Online ahead of print]AJ
- CONCLUSIONS: Midterm survival and clinical outcomes after MMPRR were comparable between patients with intraoperative Outerbridge grades 0 to 2 and grades 3 and 4, with no significant differences in failure rate or survival. The overall median survival was 11 years, with an 80% survival rate at 8 years. The change in IKDC score exceeded the MCID in both groups. These findings indicate that MMPRR is durable and effective and intraoperative Outerbridge classification grades should not dissuade orthopaedic surgeons from performing MMPRR.

- 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. [Journal Article]Am J Sports Med. 2026 Jul 12; :3635465261463006. [Online ahead of print]AJ
- CONCLUSIONS: AI cannot replicate the nuanced judgment of human peer reviewers at a high-impact sports medicine journal. When AI recommended rejection or cascade, 90.5% of manuscripts received that final decision (descriptive PPV, 90.5%; 95% CI, 71.1%-97.3%), suggesting potential utility as an exploratory first-pass screening tool warranting further validation in larger cohorts. However, AI could not reliably distinguish manuscripts destined for outright rejection from those that would be cascaded to a sister journal-an important limitation for editorial triage applications.

- Association of Early Knee Extension Range of Motion Deficits With Cartilage T2 Relaxation Following Anterior Cruciate Ligament Reconstruction. [Journal Article]Am J Sports Med. 2026 Jul 12; :3635465261462587. [Online ahead of print]AJ
- CONCLUSIONS: Knee extension ROM deficits at 2 months post-ACLR are associated with early compositional changes in the medial femoral cartilage, indicating a potential relationship between limited extension and OA risk.

- CONCLUSIONS: ACLR-induced pressure center displacement coincides with focal posterior cartilage degeneration, forming a spatiotemporal mechanical-pathological chain. This work highlights the potential of dynamic loading biomarkers for early osteoarthritis risk stratification and targeted mechanical intervention.

- Nerve Growth Factor Gene Delivery via Nanosphere-Hydrogel Composites and Tendon-Bone Interface Healing in a Rat Rotator Cuff Tear Model. [Journal Article]Am J Sports Med. 2026 Jul 07; :3635465261449709. [Online ahead of print]AJ
- CONCLUSIONS: NGF gene delivery effectively enhances TBI healing in a rat model of acute RCT histologically, structurally, and functionally via NP-GEL composites, accompanied by mild upregulation of NT-3 and increased HO, although not in clinically concerning regions. Thus, this strategy holds translational potential to improve the clinical outcomes of RCTs.

- Weakening of the Active Muscle Restraint Against Valgus Loading During Repeated Baseball Pitching: Direct Evidence of Fatigue in Dynamic Valgus Stabilizers of the Elbow Joint in Collegiate Baseball Pitchers. [Journal Article]Am J Sports Med. 2026 Jul 06; :3635465261460711. [Online ahead of print]AJ
- CONCLUSIONS: Pitchers' medial elbow muscular varus strength decreased by a mean of 10% after 7 innings of 15 pitches, while motion-dependent valgus load remained fairly constant throughout the 7 innings, which could indicate increased reliance on the UCL to withstand the valgus loads in later innings.

- CONCLUSIONS: This 5-type classification system demonstrated high reproducibility (ordinal κ≈ 0.90) and clinical validity, providing a practical framework for standardized reporting and treatment selection and a defensible stratification scheme for future trials and meta-analyses.

- Comparison of Long-term Supraspinatus Tear Progression After Arthroscopic Isolated Subscapularis Repair With and Without Comma Tissue Preservation: A Minimum 10-Year MRI Follow-up Study. [Journal Article]Am J Sports Med. 2026 Jul 03; :3635465261460741. [Online ahead of print]AJ
- CONCLUSIONS: Disruption of the comma tissue was associated with a higher risk of long-term supraspinatus tear progression and worse clinical outcome scores compared with the in-continuity comma tissue technique. Although 6 months is an appropriate time point to assess subscapularis tendon integrity, continued clinical deterioration should prompt evaluation for secondary supraspinatus tear progression.
