Aberrant Gait Biomechanics Linked to Cartilage Changes After ACL Reconstruction in Those With High Body Mass Index

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT A history of anterior cruciate ligament reconstruction (ACLR) and high body mass index (BMI) are strong risk factors for incident knee osteoarthritis. Limited research has evaluated the interaction between ACLR and high BMI on limb‐level loading and early deleterious changes in cartilage health.

Advanced Testing Protocols Simulate Failures and Validate Antioxidant Polyethylene in Ankle Implants

open access: yesJournal of Orthopaedic Research, EarlyView.
Abstract Total ankle replacement (TAR) has become an effective treatment for end‐stage ankle osteoarthritis. Multiple factors, including patient characteristics, surgical technique, alignment, and bearing surfaces, influence TAR survivorship. Polyethylene (PE) fatigue is a key consideration in improving outcomes.

Multi‐Scale Analysis of Regional Pathology in the Human Trapezium During Osteoarthritis Progression

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Trapeziometacarpal (TMC) osteoarthritis (OA) is a prevalent condition that significantly impacts hand function and quality of life. In this study we sought to close gaps in knowledge related to the initiation and progression of TMC OA on the tissue scale by evaluating the morphology and gross appearance, wear patterns, mechanical properties ...

Comparison of External Rotation Torque of Short External Rotator Muscles in Hip Flexion Position

open access: yesJournal of Orthopaedic Research, EarlyView.
Preserving the short external rotator muscles of the hip helps prevent dislocation after total hip arthroplasty, but it's unclear which muscles are most critical. This study quantified the external rotation torque in cadaveric hips and found that the obturator externus provides the highest torque during deep hip flexion, where dislocations often occur.
