    Abstract: A cutting assembly for resecting a patient's patella during knee surgery comprises a cutting instrument having a cutting head for cutting the patella on a selected resection plane, and a patella clamp having opposing jaws which can be moved towards one another to clamp the patella between them. The clamp provides a reference surface for engaging the posterior surface of the patella, and a support surface for supporting the cutting head of the cutting instrument, thereby locating the cutting instrument relative to the clamp. The assembly includes a plurality of connector inserts which can be mounted individually or in one or more combinations on or relative to the clamp, providing a physical connection between the reference and support surfaces which defines the inclination of the support surface relative to the reference surface so that the inclination of the support surface relative to the reference surface can be varied by changing one or more of the connector inserts.

    Abstract: A patella clamping device has a handle having a first arm and a second arm, the arms each having a first gripping end and a second clamping end. The clamping ends are movable towards the opposite arm by action on the gripping end of each arm. The clamping ends of the first and second arms comprise opposed clamping surfaces. The clamping end of each arm has a body portion having spaced first and second surface defining the opposed surface of each arm. A plurality of pins extend from the first to the second surface. A rotatable toothed jaw member is pivotally mounted on each of the pins. The jaw member has at least one tooth extending outwardly of the opposed surface of each arm for engaging the patella. Each body has a third surface spaced from the second surface to create a slot for receiving a saw blade.
