A modular prosthetic device is provided for replacement of the knee. The device is assembled from a plurality of components, each of which can be inserted through a small incision. After inserting the components through the incision, the device can be assembled within the knee cavity. The modularity of the device enables a surgeon to replace only those regions of the knee that are diseased or damaged, thereby avoiding a complete knee replacement. If, at a later time, additional regions of the knee become diseased or damaged, those additional regions of the knee can be replaced by additional device components and those additional components can be connected to the previously implanted components. By replacing only those regions of the knee that are diseased or damaged and by implanting each of the components through the small incision, the surgery is minimally invasive and, therefore, requires reduced time for healing and rehabilitation.

L'invention concerne un dispositif de prothèse modulaire destiné à remplacer un genou. On assemble le dispositif à partir d'une pluralité de composants, chacun de ceux-ci étant inséré par une petite incision. Après insertion des composants par l'incision, le dispositif peut être assemblé dans la cavité du genou. La modularité du dispositif permet au chirurgien de ne remplacer que les régions du genou qui sont malades ou endommagées, ce qui permet d'éviter un remplacement du genou complet. Si, ultérieurement, des régions supplémentaires du genou sont malades ou endommagées, celles-ci peuvent être remplacées par des composants supplémentaires pouvant être liés aux composants déjà implantés. Le fait de ne remplacer que les régions malades ou endommagées du genou, et d'implanter chacun des composants à travers la petite incision permet de mettre en oeuvre une intervention peu vulnérante, qui requiert des temps réduits de guérison et de réadaptation.
