Modulare Gelenkprothese

Basic implantable joint is adapted such that addable component(s) thereto can be added to the basic joint without removal of the joint from the site to which it can be initially implanted to provide a modular joint. Other modular features to a basic implantable joint are provided as well. The modular joint can be, for example, that of the knee and include a basic, implantable femoral component having, say, a receiving housing (1), with the addable component(s) or module(s) (30) able to be added thereto inter-condylarly, which, for example, can include an insertable rotation device with a swingable, depending male type part (50); intramedullary femoral spike (37) and/or posterior stabilizing stop (35).
