Femoral implant and tibial implant, in particular as part of a knee prosthesis, and knee prosthesis comprising a corresponding femoral implant and / or tibial implant

摘要

A femoral implant (20), in particular as part of a knee prosthesis, comprising a patellar guide track (21) having a proximal (22) and a distal (23) section, a lateral condylar element (26) and a medial condylar element (27), the width of the patellar guide track (21) increases from the distal (bd) to the proximal portion (bp), such that a patella or patellar implant slides on the patella lane (21) independent of an anatomical Q angle.
