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.1

Reported benefits of the Oxford knee include "conservation of normal structures, knee kinematics and proprioceptions"1

Oxford Cemented PKR Design Features:

  • Tibial Component: anatomical shape for optimal bone coverage
  • Femoral Component: the conforming, spherical design minimizes contact stress throughout entire range of motion and the curved inner geometry is designed for minimal bone removal2
  • Mobile Meniscal Bearing: designed to replicate the meniscus and remain fully congruent with the femoral component throughout the entire range of motion3

Clinically Proven

  • 94.0% Kaplan Meier Survivorship at min 15 years (675 knees)4-6
  • 91.0% Kaplan Meier Survivorship at min 20 years (16 knees)4
