Atraumatic osteonecrosis of the humeral head: pathophysiology and current concepts of evaluation and treatment

JSES Reviews, Reports, and Techniques, 2022
The humeral head is considered the second most common site for osteonecrosis to occur after the femoral head. As seen in the femoral head, the circulatory implications characteristic of this condition are attributable to the interaction between a genetic

Sport participation after isolated distal femoral osteotomy in young patients: High return‐to‐sport rates and predictive role of preoperative activity level

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The present study aimed to assess return to sport (RTS) rate, activity level and return to work (RTW) in young, physically active patients who underwent isolated distal femoral osteotomy (DFO) for lateral knee pain and valgus malalignment.

GDF11 alleviates glucocorticoid-induced osteonecrosis of the femoral head by regulating angiogenesis via the PI3K-AKT-eNOS pathway

Communications Biology
Glucocorticoid-induced osteonecrosis of the femoral head is a joint dysfunction disease. Impaired local angiogenesis and reduced perfusion are early pathological features of glucocorticoid-induced osteonecrosis of the femoral head, resulting from ...

Bisphosphonates for Post-COVID Osteonecrosis of the Femoral Head

JBJS Open Access, 2022
Background:. COVID-19 infection can cause long-term effects, cumulatively known as long COVID syndrome. One such sequela is osteonecrosis of the femoral head (also called avascular necrosis of the femoral head, or AVNFH).

Specific functional knee phenotypes are associated with increased osteoarthritis progression: A ≥10‐year longitudinal study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate osteoarthritis (OA) progression across functional knee phenotypes (FKPs) over a follow‐up period of ≥10 years. Methods This retrospective longitudinal study included 388 patients (764 knees) with healthy knees or early OA (Kellgren–Lawrence grade ≤1) at baseline and a minimum follow‐up of 10 years.

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.
