Knee Wear

Wear is a function of loss of the polyethylene on the tibial side and in the same way as the hip this polyethylene debris then causes a cellular reaction of the macrophages and the macrophages release cytokines or small chemicals which further cause bone resorption in effect melts the bone away from the cement of the prosthesis causing a secondary loosening process.  It is dealt with in a similar manner to loosening.
