Patellofemoral osteoarthritis is associated with smaller hip muscle volumes than healthy controls

Abstract

Introduction: The patellofemoral joint osteoarthritis (PFJOA) is common and associated with knee pain and reduced physical function. However, currently there is limited knowledge of the modifiable impairments associated with PFJOA, which could be targeted in rehabilitation programs. Hip muscle dysfunction may influence PFJ stress and hence, be important in PFJOA. Therefore, the aim of this study was to compare the volumes of the primary hip-abductors (gluteus medius, gluteus minimus and tensor fasciae latae) of individuals with PFJOA, with those of healthy controls.
