Persona® Partial Knee

Building on a clinically proven legacy1,2, the Persona Partial Knee is the next era in personalization in fixed bearing partial knee design providing:

  • Compartment-specific shapes based off the Persona® Total Knee, which has the finest sizing increments available3
  • Precise, efficient instrumentation
  • An ergonomic spacer block technique with fewer steps*

Personalized Implants, Designed for Optimal Fit and Function

Unlike some other fixed bearing PKRs the Persona Partial Knee offers a range of sizes with:

  • Improved sizing options mirroring the native tibia*
  • Better shape matching, with increased tibial coverage aimed at preventing subsidence
  • Improved patella flange geometry* designed to reduce soft tissue irriation and contact with the patella.4

Replicating Nature’s Anatomy

Persona Partial Knee surgeon developers and engineers studied the morphology of thousands of bones, representing a diverse global population, including use of ZiBRA™ virtual resection technology.

ZiBRA technology was used to design implants for the Persona Knee Family, aiming to provide a more precise fit without compromise.

Clinically Proven Legacy1,2

Foran, JR. et al.1 reported a 98% survivorship of the Miller Galante Uni at 10 years and 90% at 20 years.

In a study by Berger, RA. et al. thirty-nine Miller Galante Uni knees (80%) had an excellent result, six (12%) had a good result, and four (8%) had a fair result.2

Proven Bearing Technology: Vivacit-E® Vitamin-E HXPE**

  • Vivacit-E Polyethylene is actively stabilized with Vitamin-E designed to protect against oxidation and maintain wear resistance4 and strength5-7 throughout the life of the implant
  • This proprietary material is designed to meet the demands of today’s fixed bearing partial knee patients
