Résumé / Abstract
Over the last 10 years, several studies analyzed 3D joint space of the knee and deduced articular contact kinematics during various weight-bearing activities. Joint space and articular contact kinematics provide relevant data on how the intrinsic biomechanics of the knee is altered after a disease or a surgical procedure, such as knee osteoarthritis (OA) or total knee arthroplasty. Although very accurate, the methods employed by these studies require complex acquisition protocols, implying 3D/2D registration techniques or MRI-based methods, which turn out unusable in clinical routine. The goal of the present study is to assess the feasibility of a new method to estimate 3D joint space of the knee during dynamic weight-bearing squats, which are the second most studied activity in orthopedics performed by healthy and OA subjects. To our knowledge, this method based on motion capture has never been proposed before.
