Completed

Conditions studied: Arthroplasty, Replacement, Knee, Osteoarthritis, Knee

In brief

25 subjects implanted with a Zimmer-Biomet Posterior Cruciate Retaining (PCR) total knee arthroplasty (TKA) and 25 subjects implanted with a Zimmer-Biomet Posterior Stabilizing (PS) TKA will be asked to perform stepping up and deep knee bend activities while under fluoroscopic surveillance (x-ray video). The movements between the two different types of TKAs will be compared.
