Abstract: A device for setting a total knee prosthesis includes: a tensioning component (1) having: a tibial plate (2), a slide (5) mobile along a rail (3) and elements (6, 11) for being fixed to an ancillary component including a centro-medullar rod and a tibial plate and capable of receiving variable-width wedging elements; and a motoring elements (8, 10) for tensioning the knee when the plate is applied on a tibial section and the ancillary component (20) secured to the slide, a perforating guide capable of being mounted on the rail (3) and having drilling holes; the guide capable of including or of being associated with a member for palpation of the anterior part of the femur; and locating elements (EF) for determining the interarticular space available in flexure, thereby enabling the distal femoral section plane or the posterior section plane to be accurately determined.

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.
