Survivorship at 20 years


91.0% Kaplan Meier Survivorship at min 20 years (14 knees)2

System Features

The Oxford Partial Knee offers surgeons a partial knee replacement that is less invasive and has demonstrated lower morbidity and pain scores when compared to total knee replacement.6

Reproducible Microplasty Instrumentation

Microplasty Instrumentation simplifies the surgical technique, providing for accurate and reproducible implant positioning.8 Microplasty instrumentation also shows a reduction in OR time of almost 9 minutes,9 reduced risk of dislocation10 and improved alignment11 compared to Phase 3 Instrumentation.




Patient Satisfaction

  • After one year, a randomized, controlled study showed that significantly more partial knee patients would have the operation again compared to total knee patients.13

Less Complications

  • A multi-center study demonstrated decreased morbidity and complications of PKA compared to TKA14

Proven2 and reproducible technique

  • With Microplasty® Instrumentation8

Best-in-class continuous education program

  • Providing in-person and virtual training opportunities

Patient Preference

  • 46% of patients would choose a PKR over a TKR when presented with the various risks and benefits of both options.15 This is significantly higher than the 10% of knee replacement patients who receive a PKR today.16

Less Opioid Usage

  • A study showed that PKR patients require fewer narcotics following surgery, for a shorter duration of use, less refills, and have a lower likelihood of narcotic requirement at 4 weeks.17

Important Safety Information

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. The Oxford Partial Knee 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.
