Medial Meniscus Posterior Root Repair in Knees With ≥5° of Varus Alignment Is Associated With Greater Osteoarthritis Progression Compared With <5° Varus Alignment

May 8, 2026

The authors aimed to assess the impact of mechanical alignment on the progression of osteoarthritis (OA) following isolated medial meniscus posterior root (MMPR) repair. Their findings indicate that knees with varus alignment (≥5°) experienced significantly greater OA progression, higher rates of repair failure, and increased conversion to total knee arthroplasty compared to those with normal alignment (<5°), despite similar patient-reported outcomes. The study highlights the importance of baseline alignment and repair integrity as critical factors influencing postoperative joint survival.

Surgical Management of SLAP Lesions in Baseball Throwers: Posterosuperior and Posterior Labral Debridement With or Without Anterosuperior Repair Yields High Return to Play Rates

May 8, 2026

The authors aimed to evaluate the clinical outcomes and return to play (RTPL) rates of a surgical strategy for managing SLAP lesions in competitive baseball throwers, specifically comparing posterosuperior and posterior labral debridement with or without anterosuperior repair. Their findings indicated a high overall RTPL rate of 79%, with no significant differences between the two surgical approaches, suggesting that avoiding rigid fixation of the posterosuperior labrum may enhance recovery outcomes for these athletes.

Clinical Utility of the Moving Valgus Stress Test and Milking Maneuver for Medial Ulnar Collateral Ligament Injuries of the Elbow

May 6, 2026

The authors aimed to assess the clinical utility of various special tests for detecting medial ulnar collateral ligament (MUCL) injuries in athletes. They found that the moving valgus stress test had the highest sensitivity and accuracy for ruling out MUCL injuries, while the milking maneuver was more effective for confirming such injuries. Overall, no combination of tests improved diagnostic utility beyond the individual assessments.

The Modified Budin View: A Reliable and Accessible Screening Tool for Femoral Version Deformities in Joint-Preserving Hip Surgery

May 6, 2026

The authors aimed to evaluate the reliability and diagnostic accuracy of the modified Budin view as a screening tool for femoral version deformities in young patients undergoing joint-preserving hip surgery, comparing it to established imaging methods like CT and MRI. Their findings indicate that the modified Budin view is a highly reliable and accessible method, demonstrating excellent intra- and interobserver reliability and high diagnostic accuracy for identifying abnormal femoral version. This suggests it could serve as a valuable alternative in clinical practice where traditional imaging methods may be limited.

Return to Sport in Professional Athletes With Borderline Hip Dysplasia After Hip Arthroscopy for Femoroacetabular Impingement

May 4, 2026

The authors aimed to determine the return-to-sport (RTS) rates for professional athletes with borderline hip dysplasia following hip arthroscopy for femoroacetabular impingement (FAI). They found that 79% of athletes who underwent primary hip arthroscopy successfully returned to their sport, with a median return time of 7.5 months, while only 25% of those undergoing revision surgery returned. Factors such as older age and a history of previous hip arthroscopy were associated with a lower likelihood of RTS.

Return-to-Work and Clinical Outcomes After Anterior Latissimus Dorsi and Teres Major Tendon Transfer for Irreparable Subscapularis Tears

Apr 22, 2026

The study aimed to evaluate the clinical outcomes and return-to-work (RTW) rates following anterior latissimus dorsi and teres major tendon transfer in patients with irreparable subscapularis tears. The findings indicated that the procedure resulted in significant improvements in clinical outcomes and a high overall RTW rate of 91%, with lighter work demands and intact tendon integrity being key predictors of successful RTW.

Statistical Robustness of Randomized Controlled Trials Comparing Biceps Tenotomy Versus Tenodesis: A Reverse Continuous Fragility Index Analysis

Apr 22, 2026

The authors aimed to assess the statistical robustness of nonsignificant outcomes in high-quality randomized controlled trials comparing biceps tenotomy and tenodesis during shoulder arthroscopy. Their analysis, using the reverse continuous fragility index (rCFI), revealed that while the studies generally indicated noninferiority in clinical outcomes, a significant portion of the nonsignificant results could be reconsidered as significant, suggesting moderate robustness in the findings. Overall, the study highlights the importance of evaluating statistical fragility in interpreting clinical trial results.

Association Between Posterior Tibial Slope and Graft Survival in High-Risk Anterior Cruciate Ligament Reconstruction With Lateral Extra-articular Tenodesis

Apr 22, 2026

This study investigates how posterior tibial slope (PTS) influences graft survival in high-risk anterior cruciate ligament (ACL) reconstruction patients who also underwent lateral extra-articular tenodesis (LET). The authors found that PTS independently predicts graft failure, with a stronger effect in high-risk patients, and identified specific PTS ranges that correlate with lower failure probabilities. Ultimately, while LET offers some protection, higher PTS values are associated with increased rerupture risks, suggesting that steeper slopes may diminish the benefits of the adjunctive procedure.

Triamcinolone Acetonide Is Not Harmful to Healthy and Osteoarthritic Human Knee Cartilage

Apr 21, 2026

The authors aimed to investigate the effects of intra-articular triamcinolone acetonide (TA) on chondrocyte viability and matrix metabolism in healthy and osteoarthritic human knee cartilage. They found that TA did not harm chondrocyte viability and only modestly reduced matrix synthesis at high concentrations, suggesting that TA poses minimal risk to cartilage integrity when used clinically for managing joint synovitis. These results support the continued use of TA in clinical practice without significant concerns for direct cartilage damage.

Progressive Cartilage Degeneration After Anterior Cruciate Ligament Reconstruction: Longitudinal Evidence From the Swedish Knee Ligament Registry

Apr 20, 2026

This study aimed to evaluate the progression of cartilage damage in patients undergoing anterior cruciate ligament reconstruction (ACLR) by comparing findings from primary and revision surgeries. The results indicated a significant increase in the prevalence, size, and severity of cartilage lesions over time, with older age, pre-existing meniscal and cartilage injuries, and longer intervals between injury and revision surgery identified as key risk factors for cartilage degeneration. These findings highlight the need for improved strategies to address posttraumatic joint deterioration following ACL injuries.
