Determination of friction for knee implants

Capability Description

To complement our pre-clinical wear simulation facilities we have capability to measure the friction of artificial and natural joints through a variety of methods, from simple geometrical configuration using a pin-on-plate simulator, to a pendulum friction simulator predominantly used for hip replacements, through to single station physiological anatomical hip and knee simulators. At Leeds we have the capability for the measurement of wear and friction/anterior-posterior shear force acting on the tibio-femoral articulation. Methodology has been developed to assess early inventions to cartilage repair, as well as artificial materials used for total knee arthroplasty. Tests are typically short-term (300 cycles) and are carried out in 25% bovine serum.
