Summary

In vivo knee kinematics will be assessed for 20 subjects that have been implanted with either a MicroPort Medial Pivot or DePuy Attune posterior cruciate retaining (PCR) total knee arthroplasty (TKA) by Dr. Russell Nevins of Nevada Orthopedic \& Spine Center \[this is the location from which participants will be recruited\].

Detailed description

There will be ten subjects with the MicroPort implant and ten with the DePuy Attune implant; however, we will increase enrollment to 24 subjects (12 in each group) to ensure that researchers acquire the necessary 20 usable datasets for analysis and also to account for any subjects that may drop out of the study. All TKAs should be judged clinically successful based on the surgeon's evaluation and each patient's Forgotten Knee Score. Each subject should have a well-functioning prosthesis, be at least six months post-operative, and should have good-to-excellent post-operative passive flexion.

Conditions

• Total Knee Arthroplasty
