Medial osteoarthritis (OA) and lateral OA have distinct characteristic cartilage lesion locations and knee flexion angles associated with lesion development. These types of OA are suggested to be caused by loading when the knee is in extension and mid-range flexion, respectively.

This project used subject-specific finite element (FE) models to investigate contact conditions within the extended and flexed knee. A method of creating subject-specific FE models by combining geometry (...
