摘要

Damage patterns on the articular surface of the proximal tibia, including cartilage degeneration in osteoarthritic knees and damage of polyethylene knee prostheses after total knee replacement, provide information related to knee joint biomechanics and damage mechanisms at the articular surface. This study reports articular damage patterns and knee kinematics assessed in the knees of older subjects, before and after total knee replacement. The damage patterns are used to evaluate computational dynamic contact and tribological models that predict polyethylene damage in a patient-specific total knee replacement model.
