Knee Implants and Technologies
You’re unique, and so is your individual anatomy. That’s why Zimmer Biomet knee implants and technologies are designed to help your surgeon find the right shape, size, and fit for your joint.
Not actual patients
In some cases, osteoarthritis only occurs in one side of the knee. For knees that are otherwise healthy, partial knee replacement can preserve the portions of your knee, cartilage and ligaments that are healthy, instead of replacing the whole thing. Zimmer Biomet has two, world-class partial knee implants.

Oxford® Partial Knee System
As the most widely used6 and clinically proven7,8 partial knee in the world, the Oxford Partial Knee provides for a knee replacement with less pain1,2, more natural motion4,5* and a faster recovery when using a rapid recovery protocol.3
More Oxford Partial Knee patients return to sports compared to total knee patients (e.g. swimming, cycling, hiking, golfing and walking).9
Partial knee patients have also been found to be more likely to forget their artificial joint in daily life and consequently may be more satisfied.10
Important Safety Information: The Oxford Partial Knee is intended for use in individuals with osteoarthritis or avascular necrosis limited to the medial compartment of the knee and is intended to be implanted with bone cement. The Oxford Partial Knee is not indicated for use in the lateral compartment or for patients with ligament deficiency. Potential risks include, but are not limited to, loosening, dislocation, fracture, wear and infection, any of which can require additional surgery.

Persona® Partial Knee System
Getting a precise knee implant fit is an important key to your comfort and overall experience following partial knee replacement. The Persona Partial Knee has side-specific shapes based off the Persona® Total Knee, which has the finest sizing increments available. This gives your surgeon a comprehensive selection to choose from, personalizing the balance and fit for each patient.
Talk to your surgeon about whether knee replacement is right for you and the risks of the procedure, including the risk of implant wear, infection, loosening, breakage or failure, any of which could require additional surgery.

Persona® The Personalized Knee®
When something fits well, you feel good wearing it. The Persona Knee System offers extensive implant sizes and shapes so your surgeon can tailor your implants to fit your unique anatomy and conserve more of your natural bone.
- The femoral implant comes in standard and narrow options to help your surgeon accommodate various bone sizes and widths.
- The tibial implant is designed to help your surgeon achieve the right bone placement and the right amount of bone coverage.
- The bearing implant sits between the femur and tibia. It comes in several thicknesses and constraints to help your surgeon achieve a proper balance and fit of the overall joint.
- All the Persona Knee implants are side-specific… meaning that they are designed specifically for either your right or left knee.

While uncommon, complications can occur during and after surgery. Some complications include, but are not limited to, infection, blood clots, implant breakage, malalignment and premature wear, any of which can require additional surgery. Although implant surgery is extremely successful in most cases, some patients still experience stiffness and pain. No implant will last forever, and factors such as your post-surgery activities and weight can affect longevity. Be sure to discuss these and other risks with your surgeon.
