Summary

The purpose of the study is to acquire kinematic in vivo fluoroscopy data from subjects who were implanted with Stryker Posterior Cruciate Retaining (PCR) , Stryker Posterior Stabilized (PS), Zimmer PCR, and Zimmer PS Total Knee Arthroplasty (TKAs). Our lab has previously collected data for the Smith \& Nephew PCR, bi-cruciate retaining (BCR), and bi-cruciate stabilized (BCS) TKA.

Detailed description

The objective for this study is to analyze the in vivo kinematics for subjects implanted with either a Stryker PCR, Stryker PS, Zimmer PCR, and Zimmer PS TKA and to compare those patterns to subjects having a normal knee from our previous study and to those patterns from subjects having a Smith \& Nephew PCR, BCR, and BCS TKA.
