Abstract: Method for selecting one or several knee prosthesis elements, by acquiring spatial data concerning spacing and tensioned femorotibial position, including the corresponding HKA angle, for at least three angular positions, of 20°, of 0°, and of the order of 90° in flexion, processing the data thus obtained to verify whether the HKA angles are substantially equal and included within the tolerable limits, and processing the data, in particular those corresponding to extension and flexion of 90° to determine the dimensions and/or positions of the implant.

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: The device includes at least one femoral insert (8A) with a condyle support surface (20A), for a bone or femoral implant, at least one tibial insert (10A), with a tibial plateau support surface (24A), for a bone or a tibial implant and force introduction element (4A, 30A), for application between the femoral insert and the tibial insert of a distraction force of a given intensity with the knee cap in place or not. The condyle support surface (20A) is dished in form and is provided with a sliding element (12A) for the bone or femoral implant when the knee joint is moved.

Abstract: The invention concerns a method for selecting one or several knee prosthesis elements, characterized in that it consists in acquiring spatial data concerning spacing and tensioned femorotibial position, including the corresponding HKA angle, for at least three angular positions, of 20°, of 0°, and of the order of 90° in flexion, in processing the data thus obtained to verify whether the HKA angles are substantially equal and included within the tolerable limits, and in processing said data, in particular those corresponding to extension and flexion of 90° to determine the dimensions and/or positions of the implant.
