Background: Frontal plane knee kinematics are more likely associated with the development or progression of knee osteoarthritis. However, detailed frontal plane knee kinematics remain unclear. Previous studies examined movement during gait, squatting or stair stepping which allowed compensatory motion. However, biomechanical parameters in gait analyses can be modified. Therefore, we analyzed movement during stationary stepping activity while holding a handrail. The purpose was to determine: 1) detailed 6-degrees-of-freedom kinematics during stationary stepping activity in subjects with severe knee osteoarthritis; and 2) the association between unloading and black-loading phases. Methods: Twenty-four patients (32 knees) with severe medial knee osteoarthritis awaiting total knee arthroplasty were enrolled in this study. Knee kinematics was analyzed using a 3D-to-2D registration techniqu.. View More»
