Partial Knee Replacement

Oxford® Unicompartmental Knee

Leading surgeons in Oxford, England along with engineers at Biomet, developed the Oxford® Unicompartmental Knee System. It’s the only FDA-approved, free-floating meniscal partial knee system available in the United States and has been utilized throughout Europe for more than two decades.

In patients with only limited knee arthritis, surgeons may elect to perform a unicompartmental (partial) knee replacement. Unlike total knee replacement involving removal of all the knee joint surfaces, a unicompartmental knee replacement replaces only one side of the knee joint. Knee osteoarthritis usually occurs first in the medial (inside) compartment as this side of the knee bears most of the weight. In knees that are otherwise healthy, a unicompartmental approach allows the outer compartment and all ligaments to remain intact. By retaining all of the undamaged parts, the joint may bend better and function more naturally.

In a healthy knee, the meniscus serves as a shock absorber between the ends of the bones. The Oxford® Knee is the first partial implant with an artificial meniscal bearing designed to glide freely throughout the knee’s range of motion, more closely replicating normal movement. The free floating nature of the device also improves durability of the implant.

Published long-term clinical results on the Oxford® Knee demonstrated a 98% success rate at 10 years, equaling the results of the most successful total knee replacements.1 Studies also show most patients experience a rapid recovery and more natural joint function.2

Not all patients are candidates for partial knee replacement. Biomet offers the broadest range of partial knee replacements available, providing your surgeon with unparalleled flexibility to address your condition. All provide the option of minimally invasive surgery. Your doctor has chosen the Oxford® Unicompartmental Knee to address your unique situation.
