Clinically useful 2D measurements predict patellofemoral joint force

Researchers from East Carolina University (ECU) in Greenville, NC, have identified 2D lower extremity kinematic measurements that accurately predict patellofemoral joint (PFJ) force during running and can be used clinically to identify runners at risk of injury.

PFOA prognostication: Sagittal plane factors predict worsening

Sagittal plane mechanics and forces during gait in patients with patellofemoral osteoarthritis (PFOA) can help identify those who are likely to experience worsening pain or cartilage degeneration, according to research presented in February at the annual Combined Sections Meeting of the American Physical Therapy Association in Anaheim, CA.

Years after Achilles tear, injured limb demonstrates elevated knee loading

A history of Achilles tendon rupture is associated with elevated knee loading during hopping and running, suggesting an increased risk of knee osteoarthritis and other overuse knee pathologies, according to research from East Carolina University in Greenville, NC.

Clinical single-leg hop tests can help estimate risk of OA after ACL injury

Performance on single-leg hop tests a few weeks after anterior cruciate ligament (ACL) injury can predict the risk of radiographic knee osteoarthritis (OA) five years later, according to research from the University of Delaware in Newark.

Extension correction: AFO design improves PTTD mechanics

When a lamp cord doesn’t quite reach an outlet, you reach for an extension cord. So when a custom ankle foot orthosis (AFO) didn’t quite provide the corrected forefoot abduction desired in patients with post­erior tibial tendon dysfunction (PTTD), researchers from Syracuse, NY, added a lateral extension.

Surgical shoe findings support limits on driving after bunion procedures

Patients should refrain from driving for at least six weeks after bunion surgery due to poor braking response times that are not improved with the use of surgical shoes, according to findings from the Medical University of Innsbruck in Austria.

Peak vGRF in ACL-reconstructed limb may influence collagen metabolism

After unilateral anterior cruciate ligament reconstruction (ACLR), mechanical loading in the affected limb is associated with altered patterns of collagen metabolism, according to research from the University of North Carolina at Chapel Hill that could help explain the development of knee osteoarthritis in patients with a history of ACLR.

Half shoe outperforms double rocker for offloading, but also impairs gait

A half shoe offloads the forefoot more effectively than a double-rocker full-outsole shoe with an offloading insole, but the half shoe also is more likely to alter gait, according to research from Bologna, Italy.
