Knee Joint Replacement

Knee replacement surgery is really a cartilage replacement. The knee itself is not replaced, only the damaged cartilage and bone ends. Knee replacement implants include a metal alloy on the end of the thighbone and polyethylene (plastic) on the top of the tibia and underneath the kneecap. The implant is designed to create a new, smoothly functioning joint that can prevent painful bone-on-bone contact. Your surgeon may elect to replace all or part of your knee, depending on your condition and the extent to which your knee is affected by arthritis.

Oxford® Partial Knee Replacement

For patients with knee arthritis limited to the medial compartment, surgeons may elect to perform Oxford® partial knee replacement. Some advantages of the Oxford® partial knee replacement are that it removes 75% less bone and cartilage, is less painful, enables a more rapid recovery, and provides more natural motion when compared to a total knee replacement.^1-3

The Oxford® Partial Knee is currently the only FDA-approved, free-floating meniscal partial knee system available in the United States.

Published long-term clinical results on the Oxford® Knee demonstrated a 98% success rate at 10 years and 95% at 15 years and beyond, equaling the results of the most successful total knee replacements.^4,5
