A patella cutting clamp comprises a pair of jaw members joined together in scissors-like relation for pivotal movement relative to each other about a pivot axis intermediate their ends. Each jaw member has a handle portion extending in one direction from the pivot axis and a jaw portion extending in the other direction. The jaw portions have edges facing each other that are shaped for engagement with opposite borders of a patella. Teeth along the patella-gripping edges grip and hold the patella firmly. Saw guide slots in the jaw portions lying in a common plane guide the saw when the saw cut is made. A patella elevator member is attached to the jaw members for movement along the pivot axis and has a platform portion adapted to engage the anterior aspect of the patella. A mechanism is provided for establishing and maintaining a predetermined position of the elevator member relative to the jaw members and thereby positioning the patella at a predetermined position relative to the saw guide slots. Another mechanism holds the jaw members in an adjusted position relative to each other with the jaw portions engaging and holding the patella.

A tibial insert includes a base and a post extending from the base along a longitudinal axis. The post has a medial surface, a lateral surface, and a height along the longitudinal axis. The medial surface has a medial section, and the lateral surface has a lateral section oriented substantially parallel to the medial section. The medial section and the lateral section each have a width in a substantially anterior-posterior direction that is sufficient to enable varus/valgus constraint over a flexion/extension range from extension to about 90 to 120 degrees of flexion when the tibial insert is mated with a femoral component.

A pelvic positioning device for stabilizing a patient while lying on their side in a lateral decubitus position. The device includes an anterior pelvic support mechanism including anterior support pads for contacting both pubic tubercles and the ASIS on one or both sides of the patient's body. In a preferred embodiment, the anterior pelvic support mechanism includes two ASIS pads. To provide additional stabilization an upper torso pad may be included proximate the sternum of the patient's rib cage. In addition, the device includes a posterior pelvic support mechanism including a telescopic vertical member and a crescent shaped posterior support pad. The posterior support pad is mounted by a collar to a free end of the telescopic vertical member so as to be freely rotatable in a horizontal plane parallel with the operating table. As the anterior and posterior pelvic support mechanisms are moved towards the patient's body, the posterior support pad freely rotates about the vertical member and automatically properly positions itself along the central line of the sacrum and terminating proximate the distal end of the coccyx.
