UHMWPE failure in knee joint components

pages 64 - +10p., full text

A simulation of realistic tribologic conditions in tests “in vitro” contributes significantly to the research in the field of joint replacements. In the Laboratory of Human Biomechanics, motion under low relative velocities of friction surfaces of knee joint replacements is studied. For the knee joint replacement experiments, a KKK ELO 98001 simulator is used. The simulator enables combination of rolling and sliding motion of replacement components. During the experiment, numerous debris of UHMWPE component is produced and the friction surface is irreversibly changed. Initially, the irregularities of tibial component are smoothed. Consequently, large amount of UHMWPE debris is released. Specimens were loaded for 15.105 cycles with dry or distilled water lubrication. The surface changes of specimens were evaluated.
