Femoral piece

摘要

The femoral cradle (10) has two convex arched condyle shells (11,12) that are connected anteriorly via a patella plate (13). The shells are defined by externally dorsal femoral cradle slip surfaces (11a,12a). The surface distance of the cradle in the anterior-posterior direction is 2-5% smaller than the distance of the femoral condyles (F). The cradles have one or two spigots (18,19) and a glide surface-spigot distance of 24-34mm.
