Abstract
A knee prosthesis femoral implant includes two condyles integral with a throchlea and a centro-medullary block adapted to be fixed on a support base arranged between the condyles. The implant includes a wedge linking the base and the block. There is appropriate angular positioning of the wedge and the block both in a valgus front plane and in a sagittal plane relative to the reference front plane. The wedge has flat proximal and distal faces forming between them a predetermined angle (.beta.) which, combined with an angle of inclination (.alpha.) at the base surface receiving the wedge, enables, depending on the orientation of the wedge, two different femoral valgus values for each wedge. The wedge can also have different profiles in the sagittal plane. The invention enables a wide range of possibilities for adjusting the femoral valgus and for positioning the wedge in an antero-posterior plane relative to a reference plane, with a reduced number of wedges.
