Abstract

Background:Changes in knee loading have been reported after meniscectomy. Knee loading has previously been assessed during jogging and treadmill running rather than overground running, which could give altered results.Purpose/Hypothesis:The purpose of this study was to evaluate knee function during...

It was hypothesized that the affected limb would demonstrate higher external knee adduction moment, lower knee flexion moment (KFM), and lower knee rotation moment (KRM) compared with the contralateral limb and with healthy individuals.Study Design:Controlled laboratory study.Methods:Kinematic and kinetic data were collected during running and walking in individuals after a meniscectomy and healthy individuals.
