Title
(EN) POSTERIOR STABILIZED ORTHOPAEDIC KNEE PROSTHESIS HAVING CONTROLLED CONDYLAR CURVATURE
(FR) PROTHÈSE DE GENOU ORTHOPÉDIQUE STABILISÉE POSTÉRIEURE AVEC COURBURE CONDYLIENNE COMMANDÉE
Abstract
(EN)
An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a posterior cam configured to contact a spine of the tibial bearing and a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the posterior cam of the femoral component may include a concave cam surface and a convex cam surface.
(FR)
L'invention concerne une prothèse de genou orthopédique qui comprend un support tibial et un composant fémoral configuré pour s'articuler au support tibial. Le composant fémoral comprend une came postérieure configurée pour venir en contact avec une épine du support tibial et une surface condylienne recourbée dans le plan sagittal. Le rayon de courbure de la surface de condyle diminue progressivement entre une flexion précoce et une flexion moyenne. De plus, dans certains modes de réalisation, la came postérieure du composant fémoral peut comprendre une surface de came concave et une surface de came convexe.
