Abrégé
(EN)
A knee prosthesis (410) including femoral (412) and tibial (414) implants, a tibial insert (416) and a cam post assembly (419). The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant, and may have a medial boss that aligns with the tibial implant to provide rotation about a medially displaced rotation axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert. A motion limiting structure provides limits to motion between the tibial insert and the tibial baseplate. The cam post assembly interacts with the femoral implant cam feature (444) and allows more anatomically correct rollback and femoral external rotation during knee flexion, and varus/valgus support to the femur.

La présente invention concerne une prothèse de genou (410) comprenant des implants fémoral (412) et tibial (414), un insert tibial (416) et un ensemble de montant de came (419). L'implant fémoral est fixé à un fémur et a une fonctionnalité de came et des condyles. L'implant tibial est fixé à un tibia. L'insert tibial a des surfaces articulées qui correspondent aux contours des condyles de l'implant fémoral, et peut avoir une bosse médiale qui s'aligne avec l'implant tibial pour permettre la rotation autour d'un axe de rotation déplacé de façon médiale. Un montant de came est fixé à l'implant tibial et traverse un canal de l'insert tibial. Une structure limitant le mouvement confère des limites au mouvement entre l'insert tibial et la plaque de base. L'ensemble de montant de came interagit avec la fonctionnalité de came d'implant fémoral (444) et permet un déplacement arrière et une rotation externe fémorale plus corrects sur le plan anatomique pendant la flexion du genou, et un support de varus/valgus au fémur.
