Effects of 3D-printed on Lower Extremity Biomechanics in Individuals With Knee Osteoarthritis

The purposes of this study are: (1) to determine the kinematics, kinetics, and muscle co-activation ratio of level walking and stair negotiation under three different conditions (shoes only, shoes embedded 3D printed insoles, and shoes embedded 5-degree lateral wedges), (2) to build a detailed patient-specific knee model via MR images and musculoskeletal model, then, evaluate the compressive forces acting on the medial aspect of the knee during level walking and stair negotiation.
