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.

An intraoperative leg stabilizing system has a platform with a slidable brace received in a longitudinal groove. The slidable brace supports the patient's foot. The platform also has an outrigger that pivots about a base in the platform. The outrigger can pivot up to a desired orientation. The longitudinal position of the slidable brace and the orientation of the outrigger can be fixed through locking mechanisms. The system includes a support belt that can be wrapped around the patient's thigh and then connected to the outrigger. The combination of components allows the patient's leg to be stabilized in a desired position and degree of flexion during knee arthroplasty, and to be easily released when desired for evaluation of the patient's leg in extension.

A surgical instrument support system has a support frame supported by three arms. Each arm has a plurality of ball and socket members strung in series along a cable. The arms are also connected to bases mountable to the patient's limb on the proximal and distal sides of the joint. Actuators are provided for each arm to change the tension in the cables to change the stiffness of each arm. The support system can be part of a surgical instrument system that includes a plurality of resection guides mountable to the support frame.

A keel punch impactor comprises a main body having an interior bore. A locking shaft is positioned in the interior bore of the main body, the locking shaft defining a shaft axis. An actuator is in contact with the locking shaft. The actuator is moveable between a first position and a second position. The position of the locking shaft is moved within the interior bore of the main body upon movement of the actuator. In particular, the locking shaft is moved such that the shaft axis is offset when the actuator is moved from the first position to the second position. When the shaft is moved, a head on the shaft is moved into or out of alignment with a boss extending from the main body of the keel punch impactor.

A rotationally symmetric surgical instrument for use with a computer aided surgery system which is adapted so that it is easy to check its calibration and methods of checking the calibration of such instruments are described. The instrument includes a body having a working end which includes a working point which characterises the location in space of the working end. The instrument also has a location at which a marker can be attached to the instrument. Only a single formation is located toward the working end which provides a calibration reference point for engaging with a trackable instrument. The single formation has a fixed position relative to the working point. The position of the calibration reference point relative to the marker array can be determined so as to check whether the calibration of the instrument is still accurate.

An orthopaedic surgical instrument for positioning an acetabular prosthetic component in a patient's surgically-prepared acetabulum includes a surgical tool configured to be coupled to the acetabular prosthetic component, and a gravity-based position indicator removably coupled to the surgical tool. The position indicator includes a first marking indicating a first position of the acetabular prosthetic component, and a second marking indicating a second position.

A method of surgically preparing a distal end of a femur for implantation of a femoral prosthetic component includes 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, the cutting guide of the first modular cutting block, and resecting a second portion of the distal end of the femur using a base cutting guide defined in the base cutting block.
