Abstract
A patellar resection tool has first and second gripping members adapted for relative movement between a closed position in which the patella can be held between the gripping members and an open position in which the patella can be released. The tool also has first and second handle members connected to the first and second gripping members respectively, for moving the gripping members between the open and closed positions. The first and second handle members are constrained for relative movement in a first plane and the first and second gripping members are constrained for relative movement in a second plane which is not parallel to the first plane. This allows the tool to be used in a minimally invasive surgical technique in which a patella is everted by an angle less than 90° without obstructing access to the patella.
