This revolutionary concept challenges previous designs by reproducing the natural joint kinematics. In a healthy knee, the lateral meniscus subluxes posteriorly over the edge of the tibial plateau. The Oxford Domed Lateral Partial Knee reproduces this motion1.

  • Mobile meniscal bearing designed to replicate the meniscus and remain fully congruent with the femoral component throughout the entire range of motion2
  • Reproduces natural kinematics with the mobile bearing philosophy1
  • Results show that at 1 year, average range of motion was 125˚3 with no primary dislocations
  • Shown to achieve 92.1% survivorship at 8 years, considering all revisions as failures4
  • Reduces dislocation rate due to greater entrapment of the bearing5
  • Domed articulation allows for deep flexion without impingement1
  • Multiple sizes for optimised patient fit
