Knee Surgery

The knee is made up of 3 joint zones: the internal compartment (which corresponds to the internal face of the knee), the external compartment (external face of the knee) and the patella (front of the knee). When all three are worn down by osteoarthritis (wear and tear of the cartilage in the joints), they should be replaced with a complete knee replacement. But when only one or two compartments are affected, it is better to opt for so-called “resurfacing” prostheses: a unicompartmental prosthesis (to replace one compartment of the knee) or a bicompartmental prosthesis (to replace two).
