ABSTRACT:
A method and apparatus for resecting bone includes an anterior femur resection guide assembly for performing an anterior femur osteotomy, a distal femur resecting guide assembly for performing a distal femur osteotomy, a compound posterior femur-chamfer resection guide assembly for performing an anterior femur osteotomy, and a tibia resection guide assembly for performing a proximal tibia osteotomy. The anterior femur resection guide assembly, the distal femur resecting guide assembly, the tibia resecting guide assembly, and the compound posterior femur-chamfer resection guide assembly each includes a capture plate subassembly which restricts lateral movement of a saw during resection. The distal femur resecting guide assembly and the tibia resecting guide assembly also include subassemblies for verifying the correct positioning of a distal femur and proximal tibia osteotomies.
