A patella resection assembly (10) comprises a modular handle (12) and claw member (14). The claw member is reversibly mountable on the handle so that the same modules may be used to resect the patellae of both the right and the left knees. The handle has an adjustable member (28) that carries a bone-gripping member (30). Linear movement of the adjustable member allows the same patella resection assembly to be used to securely grip patellae of various sizes.
