Abstract: A femoral component (2) for mounting onto a femur and being adapted to articulate with a tibial bearing component in a knee prosthesis comprises proximal end portions (7, 10) adapted to be oriented towards the femur when the femoral component (2) is mounted thereon, and distal end portions adapted to be oriented towards the tibial bearing component when the knee prosthesis is fully extended. The proximal end portions (7) comprise posterior proximal end portions which are located on an posterior side of the femoral component and an anterior proximal end portion (10) which is located on an anterior side of the femoral component (2). The femoral component (2) further comprises a medial condyle (13) and a lateral condyle (14) which each extend from one of the posterior proximal end portions beyond the distal portions and towards the anterior proximal end portion (10) of the femoral component (2).

Abstract: A prosthetic component (2) adapted to be mounted to a bone as part of a knee prosthesis comprises a spacing element for compensating resected bone. The prosthetic component (2) further comprises a main body (6) with a contact surface (7) configured to abut the spacing element and a fixation mechanism (9) for fixing the spacing element between the contact surface (7) and the bone. The fixation mechanism (9) comprises a receiving portion (10) located at the contact surface (7). The fixation mechanism (9) further comprises an insert (11) for insertion into the receiving portion (10) and a fastening element adapted to engage with the insert (11). The receiving portion (10) is adapted to fix the insert (11) via a bayonet joint connection such that the fastening element, extending through the spacing element and engaging with the insert (11), fixes the spacing element to the contact surface (7).
