Oxford® Partial Knee

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

It was designed to repair only one side of the knee (the medial side), and is much smaller than a total knee implant. 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.

Although a total knee replacement is the most common procedure, a less invasive approach, such as the Oxford^® Partial Knee, may be more suited to your needs. If you are still at the early stages of your osteoarthritis, so only parts (normally the medial, 'inner', compartment) of your knee have been damaged by the disease, you may be able to prevent it from spreading, and avoid having to undergo a total knee replacement. This procedure preserves the healthy parts of the joint, as it only replaces one side of the knee. This results in an artificial joint with a function that is closer to the natural knee movement.

Clinically Proven

With the research and development conducted over the last two decades, we can with confidence offer a product that produces the same high quality results as a total knee replacement.

How it works

Through the extensive research conducted in Oxford, surgeons and engineers have been able to design the Oxford^® Partial Knee which uses metal surfaces on both bones, with a low wearing polyethylene bearing in between, free to glide between the metal surfaces.

The surfaces fit one another in all positions, so the polyethylene bearing has very low wear; about three hundredths of a millimetre in a year. By retaining all the undamaged parts, in particular the cruciates, the joint bends better and has more natural function than in a total knee replacement. Also due to its less invasive nature, it leads to quicker recovery, less post operative pain and a shorter hospital stay.

Key Benefits

Survivorship after 10 years of the Oxford^® Partial Knee Replacement is 98%, results that are equal to those of the most successful total knee replacements
Partial knee replacement offers patients a rapid return to normal activities with an easier, faster, and less painful recovery
