ABSTRACT:
A space correction apparatus is provided for a knee prosthesis comprising a body and two pairs of parallel runners extending on both sides of the body in a direction perpendicular to the plane of the body and of which the spacing of the front and back parts can be adjusted independently. This apparatus makes it possible to measure the spacing between the resected parts of the tibia and the femur in the extension position and to reproduce the spacing in flexion position so as to perform resections of the femur in this latter position.
