The Oxford Partial Knee for medial compartment replacement is now available with PPS® Porous Plasma Spray & Hydroxyapatite (HA) coating for cementless fixation, and has been proven to have a survivorship rate of 97.2% at 6 years1.

  • Provides additional early fixation by using hydroxyapatite coating2
  • Reduces the incidence of radiolucencies seen under the tibial components on screened radiographs (7% incidence in cementless tibial components, compared to 75% in cemented)3
  • Designed to eliminate possible known failure mechanisms caused by poor cementing technique
  • Reduces operating time by 9 minutes4 due to elimination of cement preparation and curing time
  • The New Zealand Joint Registry shows that the Oxford Cementless PKR has approximately half the revision rate of Oxford Cemented PKR5

Features:

  • Offers twin-peg femoral design to allow for additional rotational stability
  • Plasma sprayed porous titanium coating provides mechanical interlock with the substrate6
  • Available in 5 femoral component sizes designed for optimised patient fit
  • Improved fixation compared to cemented fixation1
