Acronym: Sigma MB TKA
Brief Summary: Utilize previously developed mathematical model to determine in vivo knee mechanics kinematics forces stresses areas and sound for subjects having a Sigma Posterior Stabilizing PS mobile bearing MB total knee arthroplasty TKA There are several hypotheses for this study although the most prominent is Subjects having a Sigma RP PS TKA will experience polyethylene bearing rotation at 10 years post-operative similar to their previous evaluations at six months two years and five years
Detailed Description: 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 campost 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 campost 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 campost contact mechanics under in vivo conditions
