Knee prostheses for restoration of articulation between femur and tibia, has plane located at determined distance from rotation axis, and another plane forming determined non zero angle with rotation axis

摘要

The prosthesis (Pg) has a femoral part (10) implanted at a distal end (12) of a femur (Fe), and an insert (20) interposed between the femoral part and a tibial part (14), where the femoral part is rotatingly mounted around a rotation axis (32) that is perpendicular to another rotation axis (31). A plane is located at determined distance from the former rotation axis, where another plane is perpendicular to the former plane. The latter plane forms a determined non zero angle (beta) with the former rotation axis.
