surgical options are in relation with the evolutionary moment of the disease artrósica and with the elements of mechanical overload preexisting or developed during the evolution: axial primitive Diversions Reversibilidad of the cartilaginous injury macrocospic Disappearance of cartilaginous fabric Attends of secondary deformations to the process artrósico Degree of global destruction of the joint The first situations can be treated by interventions considered like prophylactic. When already irreversible injuries exist in the cartilage, in moderate degree, palliative interventions can be applied. Finally, when the cartilaginous fabric has disappeared and the desestructuración is important with associate deformities, is necessary to resort to radical interventions since they are the implants protésicos. The ideal attitude would be to manage to avoid, medically, the deterioration of the cartilage (1-3) but this not always is possible so, overcome the phase of condroma faded, and come the phase opened (fisuración, ulceration, disappearance completes), the cartilaginous fabric is irrecoverable (4). For this motive, between others, a high percentage of knees artrósicas, in any of his varieties. It ends up by being feeder industries of replacement for artroplastia total of knee though, during the evolutionary period, other treatments have been applied to them medicoquirúrgicos palliative.
