Investigating the Bone Bruise Patterns in Pediatric Patients With Contact and Noncontact Acute Anterior Cruciate Ligament Tears: A Multicenter Study Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Jay Moran, Jason Z. Amaral, Michael Lee, Ruth H. Jones, Preston Gross, Lee D. Katz, Annie Wang, John A. Carrino, Andrew Esteban Jimenez, Barkha N. Chhabra, J. Herman Kan, Brian G. Smith, Aharon Z. Gladstein, Scott D. McKay, Robert F. LaPrade, Peter D. Fabricant, Michael J. Medvecky
Background:In adults with anterior cruciate ligament (ACL) tears, bone bruises on magnetic resonance imaging (MRI) scans provide insight into the underlying mechanism of injury. There is a paucity of literature that has investigated these relationships in children with ACL tears.Purpose:To examine and compare the number and location of bone bruises between contact and noncontact ACL tears in pediatric

Effects of Quality of Integrity on Clinical and Structural Outcomes of Rotator Cuff Repair: A Retrospective Cohort Study of 504 Cases Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Chris Hyunchul Jo, Jung-in Lee, Kyunghoon Kim, Eunmi Ahn, Sohee Oh
Background:The clinical implications of structural integrity have been a subject of long debate. The oversimplified binary categorization of structural integrity into either healing or retear, along with faulty preoperative baselines for comparison, may contribute to the controversy.Purpose:To determine how the quality of structural integrity in a repaired cuff tendon affects both clinical and structural

Isolated Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Instability Regardless of Tibial Tubercle–Trochlear Groove Distance and Patellar Height: Minimum 5-Year Outcomes Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Elizabeth R. Dennis, William A. Marmor, Bennett E. Propp, Brandon J. Erickson, Simone Gruber, Jacqueline M. Brady, Joseph T. Nguyen, Beth E. Shubin Stein
Background:It remains unclear which subset of patients with recurrent patellofemoral instability would benefit from a concomitant bony realignment procedure in addition to a medial patellofemoral ligament (MPFL) reconstruction.Purpose:To provide midterm results for patients who underwent an isolated MPFL reconstruction as part of an ongoing prospective trial.Study Design:Case series; Level of evidence

Arthroscopic Bankart Repair for Anterior Glenohumeral Instability in 488 Adolescents Between 2000 and 2020: Risk Factors for Subsequent Recurrent Instability Requiring Revision Stabilization Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Jeffrey Kay, Benton E. Heyworth, Donald S. Bae, Mininder S. Kocher, Matthew D. Milewski, Dennis E. Kramer
Background:After arthroscopic Bankart repair (ABR) for anterior glenohumeral instability (GHI), adolescent athletes have higher rates of subsequent recurrent GHI than any other subpopulation. Elucidating which adolescents are at highest risk of postoperative recurrent GHI may optimize surgical decision-making.Purpose:To identify prognostic factors associated with subsequent recurrent GHI requiring

Effect of Glenoid Bone Loss and Shoulder Position on Axillary Nerve Anatomy During the Latarjet Procedure Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Andrew D. Carbone, Daniel Kwak, Min-Shik Chung, Michelle H. McGarry, Andrew P. Nakla, Michael B. Banffy, Thay Q. Lee
Background:The Latarjet procedure is increasingly being utilized for the treatment of glenoid bone loss and has a relatively high neurological complication rate. Understanding the position-dependent anatomy of the axillary nerve (AN) is crucial to preventing injuries.Purpose:To quantify the effects of changes in the shoulder position and degree of glenoid bone loss during the Latarjet procedure on

Culturing Osteochondral Explants Under Rotary Shaking or After Removing Bone Marrow Elements Increases Explant Cellular Viability Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Chilan B.G. Leite, Renee T. Ormsby, Julie Mekhail, Julia F. Charles, Simon Görtz, Gergo Merkely, Christian Lattermann
Background:Reduced viability in the deepest zones of osteochondral allografts (OCAs) can weaken the subchondral interface, potentially increasing the risk of failure. This reduction may result from nutritional imbalances due to uneven media distribution or interference from bone marrow elements.Purpose:To investigate whether culturing OCAs using a rotary shaker or removing the bone marrow elements

Matrix-Assisted Autologous Chondrocyte Transplantation for the Treatment of Patellofemoral Chondral Lesions: Long-term Results at a Minimum 15-Year Follow-up Am. J. Sports Med. (IF 4.2) Pub Date : 2024-08-05 Angelo Boffa, Luca Andriolo, Lucia Angelelli, Valeria Pizzuti, Giuseppe Filardo, Stefano Zaffagnini, Alessandro Di Martino
Background:A few studies have documented the long-term results of chondrocyte-based procedures for the treatment of patellofemoral cartilage lesions, but specific results are lacking after matrix-assisted autologous chondrocyte transplantation (MACT) for patellar and trochlear lesions.Purpose:To document the clinical results of MACT for the treatment of patellar and trochlear chondral defects at long-term
