Abstract:
1. A method of surgically preparing a distal end of a femur for implantation of a femoral prosthetic component, the method comprising: positioning a base cutting block and an intramedullary adaptor on the distal end of the femur such that a first end of the intramedullary adaptor is received in the medullary canal of the femur and the intramedullary adaptor is secured to the base cutting block, attaching a first modular cutting block to an anterior side of the base cutting block, resecting a first portion of the distal end of the femur using a cutting guide defined in the first modular cutting block, resecting a second portion of the distal end of the femur using a base cutting guide defined in the base cutting block, attaching a second modular cutting block to the anterior side of the base cutting block in place of the first modular cutting block, and resecting a third portion of the distal end of the femur using a cutting guide defined in the second modular cutting block, the cutting guide of the second modular cutting block extending transverse to the imaginary plane defined by the base cutting guide, wherein resecting the third portion of the distal end of the femur includes (i) advancing a cutting saw blade into contact with the distal end of the femur along a first cutting guide surface extending transverse to the imaginary plane defined by the base cutting guide, (ii) advancing the cutting saw blade into contact with the distal end of the femur along a second cutting guide surface extending transverse to the imaginary plane and orthogonal to the first cutting guide surface, and (iii) resecting a fourth portion of the distal end of the femur using a chamfer cutting guide defined in the second modular cutting block, the chamfer cutting guide extending obliquely relative to the imaginary plane defined by the base cutting guide.
