Abstract
A method of positioning a femoral prosthesis relative to a femur. The method includes forming a first curved surface on a first condyle of the femur, and securing the femoral prosthesis to the femur such that a first curved bone-engaging surface of the femoral prosthesis mates with the first curved surface formed on the femur.
Claims20
A method of positioning a femoral prosthesis relative to a femur comprising:
- forming a first curved surface on a first condyle of the femur;
- and
- securing the femoral prosthesis to the femur such that a first curved bone-engaging surface of the femoral prosthesis mates with the first curved surface formed on the femur.
The method of 1, further comprising forming an incision in a dermis relative to a knee joint of about 2 cm to about 8 cm.
A method of positioning a femoral prosthesis relative to a femur in an anatomy, comprising:
- forming a first curved surface on a first portion of the femur;
- forming a planar surface on the femur;
- and
- positioning the femoral prosthesis to mate with both the first curved surface and the planar surface.
A method of positioning a femoral prosthesis relative to a femur in an anatomy comprising:
- forming a first bone hole in a first condyle of the femur;
- mounting a guide track to the femur at the first bone hole;
- forming a planar surface on the femur using a cutting guide block slidably mounted to the guide track;
- forming a first curved surface on the first condyle;
- and
- securing the femoral prosthesis to the femur such that a first curved bone-engaging surface of the femur mates with the first curved surface formed on the first condyle.
