of motion, i.e., anterior-posterior and exion-extension (at sliding specimen and

rotating disc) out of six degrees of motion of knee joint, similar equipment was built.

Flannery et al. (2008) simulated the same two degrees of motion in three-station

wear simulators to measure wear of tibial inserts.

1.3 CONCLUSIONS

Various types of wear testing machines are discussed in detail, and it was found

that for actual body implants, high-end multi-axes simulators with many degrees of

freedoms a
