  • Publication number: 20180289494
    Abstract: 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.
    Type: Application

The tibial insert further configured such that the medial bearing surface extends further in an inferior direction than the lateral bearing surface and a bottom point of the medial bearing surface is disposed closer to an anterior end portion of the medial bearing surface than a posterior end portion of the medial bearing surface.

  • Patent number: 7585328
    Abstract: A anteromedial approach to arthroplasty on a knee joint of a patient. The method of arthroplasty includes an arthrotomy that includes dissecting from medial to the tibial tubercle and around the medial border of the patella and up to the proximal border of the patella.

  • Patent number: 5108401
    Abstract: 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.
