Set of femoral implants for a knee prothesis

摘要

A set of femoral implants for a knee prosthesis includes at least two femoral implants having different dimensions from each other. Each femoral implant includes an outer face suitable for cooperating with one of a patellar implant and a patella of a patient, an inner face provided with an anchoring feature for anchoring to a bone of the patient, as well as a distal part and an anterior part each defined both on the outer face and the inner face. The set is characterized in that at least the distal parts of the femoral implants are substantially identical irrespective of the dimensions of the femoral implants.

1. A set of femoral implants for a knee prosthesis, comprising:
at least two femoral implants having different dimensions from each other, each femoral implant comprising:
an outer face adapted to couple to one of a patellar implant and a patella of a patient,an inner face provided with an anchoring feature for anchoring to a bone of the patient,a distal part and an anterior part each defined both on the outer face and the inner face, wherein the distal part includes a distal inner surface delimited by a first border adapted to be flush with a border of a distal bone preparation, the anterior part includes a frontal inner surface defined by a second border adapted to be flush with a border of an anterior bone preparation, and at least the distal parts of the femoral implants are substantially identical irrespective of the dimensions of the femoral implants; wherein the distal part of each femoral implant includes a side border and a medial border which, projected in a horizontal anatomical plane, extend along straight lines delimiting a distal angle substantially between 60 degrees and 80 degrees, the distal angles of the femoral implants being substantially identical irrespective of the dimensions of the femoral implants.
