With over 40 years of clinical heritage, the Oxford® Partial Knee is the most widely used1 and clinically proven2,3 partial knee system in the world.

It's your assurance that Zimmer Biomet not only makes a proven partial knee, but we stand behind it 100%.

Could you be treating your patients with a Partial Knee Replacement?

Research shows that 47.6% of knee replacement patients are actually candidates for partial knee arthroplasty (PKA)4 and  after one year, a randomized, controlled study showed that significantly more partial knee patients would have the operation again compared to total knee patients5.

Furthermore, Liddle, AD. et al., found that surgeons utilizing PKR for under 20% of their annual knee replacements experienced an increase in their revision rate.6

In the United States (US), 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; it 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.
