Persona® Partial Knee
Building on a clinically proven legacy,1,2 the Persona Partial Knee is redefining personalization in fixed bearing partial knee design.
- Research shows that surgeons utilizing Partial Knee Arthroplasty (PKA) for at least 20% of their annual knee arthroplasties experienced a significant decrease in their revision rate.10
Benefits of PKA vs TKA include:
Retention of the ACL, which is reported to result in improved proprioception11,12
Better range of motion13,14
Shorter hospital stays16
Lower risk of postoperative complications17
The Persona Partial Knee carries forward design elements of the Zimmer Miller Galante (M/G) Uni, which showed 98% survivorship at 10 years and 90% at 20 years1 . Persona Partial Knee has its own clinical results too! 643 Persona Partial Knees were implanted, and two-year results demonstrated:3
Survivorship at 2 years98.9%
Patients were satisfied or very satisfied with the results of surgery
The Persona Partial Knee is part of the Persona Knee Family.
