Additional hypotheses:
* Subjects having a Sigma RP PS TKA will experience full ideal femorotibial contact mechanics.
* Subjects having a Sigma RP PS TKA will experience optimal cam/post mechanics.
* Subjects having a Sigma RP PS TKA will experience continuous axial rotation in deep flexion.
* Subjects having a Sigma RP PS TKA will experience optimal distribution of tibio-femoral and cam/post contact forces over a broad area on the post.
* Subjects having a Sigma RP PS TKA will experience a smooth transition of the cam on the post, not an abrupt slide as seen with fixed bearing PS TKA.
* The use of the sound sensors will detect cam/post contact mechanics under in vivo conditions.
