The most widely used¹ and clinically proven^2,3 partial knee in the world

With 45 years of clinical heritage, the Oxford Partial Knee is the most widely used¹ and clinically proven^2,3 partial knee system in the world.

The Oxford® Partial Knee Replacement is available in cementless and cemented fixation. The Oxford PKR has more than 300 publications and the Oxford Cementless Partial Knee has demonstrated 10-year survivorship of 94.15%* in the national registry of the UK. Also available as Oxford Titanium Niobium (TiNbN) and for patients suffering from lateral osteoarthritis the Oxford® Fixed Lateral can be used.

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.¹⁵This 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

Clinically Proven

Survivorship at 15 years

94.0%

At Minimum 15 Year Postoperative (432 knees)⁶

Survivorship at 20 years

91.0%

91.0% Kaplan Meier Survivorship at min 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.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.

Biomet Bone Cement R

High viscosity, non-antibiotic, radiopaque and easy handling.

X Series^™ Power System

Developed through the shared experience of an international team ofsurgeons and engineers, X Series™ Power System provides a system thatputs you in control.

Modern Cementing Technique

Zimmer Biomet’s comprehensive assortment of bone cement and products for mixing and delivery, pressurization and bone bed preparation makes for one of the most complete portfolios for Modern Cementing Technique in the market today.

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.
