Oxford® Partial Knee


Less Pain, faster recovery, more natural motion.*

Is a partial knee right for you? Only your doctor can say for sure. But we can tell you this. Knee osteoarthritis sometimes only occurs on the medial side of the joint (the side closest to your other knee). In knees that are otherwise healthy, partial knee replacement can preserve the healthy bone, cartilage and ligaments.

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,2-3 a faster recovery,1 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. Research has shown that partial knee replacements with moveable plastic bearings like the Oxford have low wear rates.14


More natural motion

In a healthy knee, the meniscus serves as a shock absorber between the ends of the bones. The Oxford Partial 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 potentially provides for a more natural motion.

New research reports that Oxford Partial Knee patients are more likely than total knee patients to be satisfied with their ability to perform activities of daily living, and to report that their knee replacement “felt normal.”**

Patients receiving the Oxford Partial Knee at a minimum of one year post-operation were:

  • 1.81 times more likely than total knee replacement recipients to report that their knee felt normal.**
  • 2.69 times more likely to be satisfied with their ability to perform activities of daily living.**

Long-term durability

The Oxford Partial Knee is the most widely used and clinically proven partial knee in the world. Published long-term clinical results on the Oxford® Partial Knee demonstrated a 92.4% survivorship at 10 years,*8-14 94.0% at 15 years,*11,13-14 and 91% at 20 years,*11 proving The Oxford® Partial Knee the most widely used and clinically proven partial knee in the world.

There is no guarantee that any implant will successfully function for a specific length of time, as there are a multitude of variables that affect the life of an implant.

Not all patients are candidates for Oxford Partial Knee replacement. You should discuss your condition and treatment options with your surgeon. Zimmer 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.

*Compared to total knee replacement

** Adjusted odds ratio-controlled for gender, age, minority, income, and center. The multi-center study was led by researchers at Washington University in St. Louis, Missouri. Patients included in the study were treated with either total knee replacement, fixed-bearing unicompartmental knee replacement, or the Oxford®Partial Knee. Centers contributing data on both total knee and partial knee replacement were Washington University, St. Louis, Missouri; Rush University Medical Center, Chicago, Illinois; and Mt. Carmel Hospital, New Albany, Ohio. Data for the study were gathered through comprehensive interviews, conducted by the University of Wisconsin, of 1,263 consecutively identified arthroplasty patients who met the inclusion/exclusion criteria. This is a Zimmer Biomet-funded study and the data is on file.
