Summary

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.

Detailed description

This study is a cross-sectional study with patients serving as their own control. The investigators will recruit 20 patients with knee osteoarthritis. Using motion capture system, force plates, wireless EMG to capture the motion data of patients during walking and stair negotiation in each condition.

Conditions

• Medial Knee Osteoarthritis

Interventions

Type	Name	Description
DEVICE	3D-printed foot orthoses	3D printed foot orthoses with arch support
DEVICE	5 degrees lateral wedge insoles	Insoles with a lateral inclination set at 5 degrees
