Total Knee Trochlear System

A femoral component of a knee prosthesis configured to be mounted to the distal end of a patient's femur, the femoral component having a bearing surface comprising:

• a pair of condylar surfaces, wherein each condylar surface has an anterior/posterior curvature;
• and
• an anterior trochlear groove between the pair of condylar surfaces,
• wherein the anterior trochlear groove is configured to engage with a patella or patellar component such that the patella or patellar component can move its relative position so that the flexion and quadriceps function of the patient is essentially normal.

A knee replacement kit comprising:

• a plurality of femoral components of a knee prosthesis configured to be mounted to the distal end of a patient's femur, wherein each of the plurality of femoral components has a bearing surface comprising:
• a pair of condylar surfaces, wherein each condylar surface has an anterior/posterior curvature;
• and
• an anterior trochlear groove between the pair of condylar surfaces,
• wherein the anterior trochlear groove is configured to engage with a patella or patellar component such that the patella or patellar component can move its relative position so that the flexion and quadriceps function of the patient is essentially normal, and
• wherein the plurality of femoral components have varying anterior trochlear grooves;
• and
• a meniscal component of a knee prosthesis,
• wherein each of the plurality of femoral components is configured to operatively engage with the meniscal component.
