ABSTRACT:
The present invention relates to a surgical tool for use in knee arthroplasty. The tool is designed to assist a surgeon to implant a knee prosthesis which will be stable when the knee is in flexion and in extension. The tool comprises a parallel pair of paddle flanges adapted for insertion into the flexion or extension gap located between resected surfaces of a proximal tibia and a corresponding distal femur. The paddle flanges are incrementally movable relative to each other to define a range of gaps extending between a minimum gap and a maximum gap between exterior surfaces thereof. The incremental movement is provided by a racked member on which one of the paddle flanges is mounted, the racked member being movable by hand operable means connected thereto and which racked member engages with a pawl to prevent movement thereof in a gap-decreasing direction when the tool is in use.
