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
