Abstract:
1. Method of resecting a distal femur and a proximal tibia in preparation for implanting a partial knee prosthesis comprising the steps of installing a spacer having a fixed spacing dimension between the distal femur and proximal tibia to establish a gap of known width therebetween, said spacer having a projecting stem, mounting a resector on said stem, aligning said resector along a selected axis represented by an alignment rod extending from said resector, pinning said resector to both said distal femur and proximal tibia using multiple pins to prevent relative movement of said resector with respect to both said distal femur and proximal tibia, and using said resector to guide resection of one of said distal femur and proximal tibia; said spacer including an arm extending axially from said stem; said fixed spacing dimension being defined by a bump extending from one side of said arm and a substantially flat surface on the other side of said arm opposite said bump; and said arm defining a recess between said bump and said stem.
