Oxford® Partial Knee


Because the Oxford® Partial Knee is designed to repair only one side of the knee, it's much smaller than a total knee implant. Other advantages of a partial knee include less pain,1-2 a faster recovery,3 and more natural motion.*4-5 And thanks to its unique mobile bearing design, the Oxford®Partial Knee is the only one of its kind in the U.S. And now, Biomet offers the industry's only partial knee Lifetime Implant Replacement Warranty+ in the U.S. Who knew a partial knee could offer so much?

The only one of its kind

  • Currently the only fully mobile bearing partial knee system available in the United States.
  • Research has shown that partial knee replacements with moveable plastic bearings have demonstrated low wear rates.*6

More natural motion

  • 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 potentially provides for a more natural motion.

Long-term durability

  • The Oxford® Partial Knee is the most widely used and clinically proven partial knee in the world.7

Not all patients are candidates for partial knee replacement. Only your orthopedic surgeon can tell you if you're a candidate for joint replacement surgery, and if so, which implant is right for your specific needs. You should discuss your condition and treatment options with your surgeon. The Oxford® Meniscal 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® Knee is not indicated for use in the lateral compartment. Potential risks include, but are not limited to, loosening, dislocation, fracture, wear, and infection, any of which can require additional surgery. For additional information on the Oxford® knee, including risks and warnings, talk to your surgeon and see the full patient risk information on oxfordknee.com or call 1-800-851-1661.

Biomet is a manufacturer of orthopedic implants and does not practice medicine. Only an orthopedic surgeon can determine what treatment is appropriate. Individual results of partial joint replacement may vary. The life of any implant will depend on your weight, age, activity level, and other factors. For more information on risks, warnings, and possible adverse effects, see the Patient Risk Information section found within Biomet.com.
