End-stage knee osteoarthritis (OA) is treated with total knee replacement, which has improved significantly over the past decade with current survival rates of 80-95% at 10 years. However, the treatment of younger, more active patients has placed emphasis on long term survivorship under increased functional demands. Current research is focussed on improvements in design and materials to meet these new and evolving design criteria..

Gait analysis, combined with pattern recognition techniques provides the means to objectively measure knee joint function during activities of daily living such as walking. This allows us to explore biomechanical factors related to implant fixation, and performance.
