Preoperative Proximal Migration of the Radial Head as an Independent Predictor of Suboptimal Outcomes After Osteochondral Autograft Transplantation for Capitellar Osteochondritis Dissecans: A Retrospective Cohort Study

Aug 6, 2026

The authors aimed to identify preoperative risk factors associated with suboptimal outcomes after osteochondral autograft transplantation (OAT) for capitellar osteochondritis dissecans (OCD) in adolescent athletes. They found that preoperative proximal migration of the radial head was the only independent predictor of suboptimal postoperative outcomes, with a cutoff value of 2.2 mm indicating a higher risk for poor results. Overall, while OAT led to significant clinical improvements, 28% of patients still experienced suboptimal outcomes.

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

Aug 4, 2026

The authors aimed to compare nonrevision reoperation rates and patient-reported outcome measures (PROM) between primary anterior cruciate ligament reconstruction (ACLR) using quadriceps tendon (QT), hamstring tendon (HT), and bone-patellar tendon-bone (BPTB) autografts. They found that QT autografts were associated with significantly higher reoperation rates for extension deficit or pain and inferior PROM scores compared to HT autografts at a two-year follow-up. This suggests that while QT autografts are becoming more popular, they may not provide the same short-term outcomes as HT autografts.

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

Aug 3, 2026

The authors aimed to evaluate the effectiveness of arthroscopic correction for pincer-type femoroacetabular impingement (FAI) in patients with acetabular retroversion, specifically assessing patient-reported outcomes and the risk of reoperation over a minimum five-year follow-up. The study found significant improvements in clinical outcomes and high rates of patient satisfaction, with low rates of revision surgery and arthroplasty-free survivorship, suggesting that arthroscopy is an effective treatment for symptomatic FAI in this patient population.

Length Changes of the Lateral Knee: Fibular Collateral Ligament, Anterolateral Ligament, and Iliotibial Band Fibers

Aug 3, 2026

This study aimed to characterize the length changes of the fibular collateral ligament (FCL), anterolateral ligament (ALL), and iliotibial band (ITB) fibers in cadaveric knees during flexion. The authors found that the FCL and ALL shortened with increased knee flexion, while the ITB fibers exhibited transient lengthening before returning to baseline at deeper flexion angles. These findings provide valuable anatomical insights that could inform graft fixation strategies in lateral knee reconstructions.

Primary ACL Repair and Reconstruction in Isolated ACL Ruptures: Forgotten Joint Scores and the Association Between Residual Laxity and Joint Awareness

Aug 3, 2026

This study aimed to compare joint awareness, clinical outcomes, and postoperative laxity between primary ACL repair and hamstring tendon autograft reconstruction in patients with isolated ACL ruptures. The findings indicated that while there were no significant differences in conventional clinical outcomes or laxity, primary ACL repair resulted in higher joint awareness scores, suggesting a function more akin to a native knee. Additionally, residual postoperative laxity was linked to lower joint awareness, highlighting its potential impact on patient perception of knee function.

Sociodemographic Predictors of Postpresentation Delay to Pediatric ACL Reconstruction and Associated Intra-articular Injury Severity

Aug 3, 2026

The authors aimed to investigate the impact of sociodemographic and structural determinants on postpresentation delays for pediatric anterior cruciate ligament reconstruction (ACLR) and their association with intra-articular injury severity and functional outcomes. They found that factors such as race/ethnicity, insurance type, and neighborhood deprivation were linked to prolonged surgical delays, which in turn correlated with an increased risk of high-grade cartilage injury. The study highlights significant disparities in access to timely orthopedic care for pediatric patients, emphasizing the need for addressing these systemic issues.

Adductor Canal Block and Local Anesthetic Versus Local Anesthetic Alone in ACL Reconstruction: A Double-Blind Randomized Controlled Trial

Aug 3, 2026

This study aimed to determine whether the combination of adductor canal block (ACB) and local infiltration analgesia (LIA) provides superior postoperative analgesia compared to LIA alone in patients undergoing anterior cruciate ligament reconstruction (ACLR). The results indicated no significant differences in postoperative opioid consumption, pain scores, or functional recovery between the two groups, suggesting that LIA alone is sufficient for effective pain management in this context. Consequently, the authors recommend against the routine use of ACB in ACLR to optimize perioperative efficiency and reduce resource expenditure.

Suprascapular Nerve Release Improves the Histological Healing Morphology and Biomechanical Strength of the Rotator Cuff in a Rat Chronic Massive Rotator Cuff Tear Model

Jul 31, 2026

The authors aimed to determine the impact of suprascapular nerve (SSN) entrapment on tendon healing and whether SSN release enhances recovery in a rat model of chronic massive rotator cuff tears (MRCTs). Their findings indicate that SSN entrapment is prevalent and that SSN release significantly improves both the biomechanical strength and histological healing of the rotator cuff, suggesting potential clinical benefits for patients undergoing MRCT repair.

Mid- to Long-term Outcomes of Coracoclavicular Ligament Reconstruction for Acromioclavicular Joint Dislocations: A Systematic Review of Studies With Minimum 5-Year Follow-up

Jul 30, 2026

The authors aimed to evaluate the mid- to long-term clinical and radiographic outcomes of coracoclavicular ligament reconstruction for acromioclavicular joint dislocations, specifically focusing on studies with a minimum 5-year follow-up. Their systematic review of 16 studies involving 326 patients revealed excellent functional outcomes, high patient satisfaction, and low recurrence and reoperation rates, regardless of the surgical approach used. Additionally, they noted that while complications such as ossification and arthritic changes occurred in some cases, overall outcomes remained favorable.

Selective Epiphysiodesis of the Anterior Distal Femoral Physis Alters Trochlear Morphology in a Rabbit Model

Jul 30, 2026

The authors investigate how selective closure of different regions of the anterior distal femoral physis affects trochlear morphology in a rabbit model, aiming to understand its role in trochlear dysplasia and patellofemoral instability. Their findings demonstrate that targeted epiphysiodesis alters trochlear shape in a region-specific manner, suggesting that growth modulation strategies could be beneficial in managing early dysplastic changes in skeletally immature patients. This research emphasizes the importance of the anterior distal femoral physis in trochlear development and informs potential surgical interventions.
