[Materials and shapes: the compromise].
The development and fabrication of a prosthesis of the knee which for many years will fulfil the functions of a normal knee result from a very complex compromise between materials and shapes. It is essential to select materials and shapes whose characteristics are complying with the specifications laid down for this particular arthroplasty. Materials ans shapes must in the long term be able to solve all the problems of biomechanics, flow, wear, friction and fixation to the osseous elements, without underestimating the interactions between implant and biological environment which may result in deterioration of the bone-implant interface.
