Partial Knee Interactive Overview

Clinical Results

45 Years: With 45 years of clinical heritage, the Oxford Partial Knee is the most widely used¹ and clinically proven²^,³ partial knee system in the world.

Survivorship at 15 Years

At minimum 15 years postoperative (432 knees).⁴

Survivorship at 20 Years

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

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.⁴

Reproducible Microplasty® Instrumentation: Microplasty Instrumentation simplifies the surgical technique, providing for accurate and reproducible implant positioning.⁵ Microplasty instrumentation also shows a reduction in OR time of almost 9 minutes,⁶ reduced risk of dislocation⁷ and improved alignment⁸ compared to Phase 3 Instrumentation.

Benefits

Less Complications

A multi-center study demonstrated decreased morbidity and complications of PKA compared to TKA.⁹

Proven* and Reproducible Technique

With Microplasty Instrumentation.⁵

Patient Satisfaction

After one year, a randomised, controlled study showed that significantly more partial knee patients would have the operation again compared to total knee patients.¹⁰

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.¹¹ This is significantly higher than the 10% of knee replacement patients who receive a PKR today.¹²

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.¹³
