Regulation of the Patellofemoral Contact Area: an Essential Mechanism for Maintaining Physiological Patellofemoral Joint Kinetics?
INTRODUCTION: Reduced patellofemoral (PF) contact area, elevated pressure and increased patellar tilt are often associated with anterior knee pain. Therefore, quantification of biomechanical parameters that characterize both the kinematics and the kinetics of the joint in an experimental, as well as clinical setting, is of increasing importance. Whilst a number of approaches have been suggested...
متن کاملWeight-bearing MRI of patellofemoral joint cartilage contact area.
PURPOSE To measure contact area of cartilage in the patellofemoral joint during weight bearing using an open MRI scanner. MATERIALS AND METHODS We developed an MR-compatible back support that allows three-dimensional imaging of the patellofemoral cartilage under physiologic weight-bearing conditions with negligible motion artifact in an open MRI scanner. To measure contact areas, we trained o...
متن کاملThe Effect of High Heel Shoes on Tibiofemoral and Patellofemoral joint Contact Forces and Muscle Forces
Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking. Materials & Methods: A tot...
متن کاملThe effect of bracing on patella alignment and patellofemoral joint contact area.
PURPOSE To examine the influence of two patellofemoral braces on pain response, patellar alignment, and patellofemoral joint contact area in persons with patellofemoral pain. METHODS Fifteen women between the ages of 18 and 45 yr with a diagnosis of patellofemoral pain participated. After the assessment of pain response using a visual analog scale, subjects underwent axial plane magnetic reso...
متن کاملContact area and pressure distribution in the feline patellofemoral joint under physiologically meaningful loading conditions.
The purpose of this study was to determine contact area and mean and peak pressures in the healthy feline patellofemoral joint over the complete range of possible applied force. Furthermore, we wanted to improve upon the repeatability of previous measurements while maximizing the physiological relevance of the results obtained. The patellae and femora were secured in a loading frame approximati...
