Randomized Control Trial Comparing Zimmer Biomet Persona Medial Congruent Versus Posterior Stabilized Total Knee Arthroplasty for Treatment of Knee Arthritis Using the ROSA Knee System
NYU Langone Health
Summary
A randomized, controlled study comparing two total knee implant devices, Persona medial congruent (MC) vs posterior stabilized (PS). These surgeries will be performed using the ROSA robotic system. Patients will be followed up to 5 years.

Interventions
- DeviceZimmer-Biomet Persona Medial Congruent (MC) Bearing Design
TKA will be performed using the MC Bearing Design. The MC bearing provides medial stability and lateral mobility to facilitate more natural motion.
- DeviceZimmer-Biomet Persona Posterior-Stabilized (PS) Bearing Design
TKA will be performed using the PS Bearing Design. The PS bearings are designed to provide ±1.5 degrees varus/valgus constraint and ± 5.5 degrees internal/external rotation constraint.
