TIBIAL PROSTHESIS SYSTEM
A tibial prosthesis system for knee arthroscopy may include a tibial tray having an anterior portion, a posterior portion, a bone facing surface, a joint facing surface, and a central aperture. The tibial prosthesis system may also include a clip configured to be slidably received in the central aperture. The posterior portion may include a posterior notch. The central aperture may extend posteriorly from the anterior portion, and from the bone facing surface to the joint facing surface. At least a portion of the joint facing surface may extend between the central aperture and the posterior notch.
1 . A tibial prosthesis system for knee arthroplasty, the tibial prosthesis system comprising:
a tibial tray comprising an anterior portion, a posterior portion, a bone facing surface, a joint facing surface, and a central aperture; and
a clip configured to be slidably received in the central aperture;
wherein:
the posterior portion comprises a posterior notch;
the central aperture extends posteriorly from the anterior portion, and from the bone facing surface to the joint facing surface; and
at least a portion of the joint facing surface extends between the central aperture and the posterior notch.
2 . The tibial prosthesis system of claim 1 , wherein the central aperture is configured to receive a natural ligament or a ligament graft.
3 . The tibial prosthesis system of claim 1 , wherein the tibial tray comprises a central axis equidistant between the anterior portion and the posterior portion, and the central aperture extends posteriorly beyond the central axis.
4 . The tibial prosthesis system of claim 1 , wherein the clip comprises an anterior profile configured to align with an anterior edge of the anterior portion of the tibial tray.
5 . The tibial prosthesis system of claim 1 , wherein the clip extends from the bone facing surface to the joint facing surface.
6 . The tibial prosthesis system of claim 1 , wherein, with the clip received in the central aperture, at least a portion of the central aperture remains unobstructed between the bone facing surface and the joint facing surface.
7 . The tibial prosthesis system of claim 1 , wherein, with the clip received in the central aperture, the central aperture is completely obstructed.
8 . The tibial prosthesis system of claim 1 , further comprising a first stem and a second stem, wherein both the first stem and the second stem are configured to be embedded within a tibia to inhibit movement of the tibial prosthesis system relative to the tibia.
9 . A tibial prosthesis system for knee arthroplasty, the tibial prosthesis system comprising:
a tibial tray comprising an anterior portion, a posterior portion, a central axis, and a central aperture; and
a clip configured to be received in the central aperture;
wherein:
the central axis is equidistant between the anterior portion and the posterior portion;
the posterior portion comprises a posterior notch; and
the central aperture extends posteriorly from the anterior portion beyond the central axis.
10 . The tibial prosthesis system of claim 9 , wherein the central aperture is configured to receive a natural ligament or a ligament graft.
11 . The tibial prosthesis system of claim 9 , wherein, with the clip received in the central aperture, at least a portion of the central aperture remains unobstructed.
12 . The tibial prosthesis system of claim 9 , wherein, with the clip received in the central aperture, the central aperture is completely obstructed.
13 . The tibial prosthesis system of claim 9 , further comprising a first stem and a second stem, wherein both the first stem and the second stem are configured to be embedded within a tibia to inhibit movement of the tibial prosthesis system relative to the tibia.
14 . The tibial prosthesis system of claim 9 , wherein the clip comprises an anterior profile configured to align with an anterior edge of the anterior portion of the tibial tray.
15 . The tibial prosthesis system of claim 9 , wherein the tibial tray further comprises a bone facing surface and a joint facing surface, and the clip extends from the bone facing surface to the joint facing surface.
16 . A tibial prosthesis system for knee arthroplasty, the tibial prosthesis system comprising:
a tibial tray comprising an anterior portion, a bone facing surface, a joint facing surface, and a central aperture; and
a clip configured to be received in the central aperture;
wherein:
the central aperture extends posteriorly from the anterior portion, and from the bone facing surface to the joint facing surface; and
the central aperture is configured to receive a natural ligament or a ligament graft.
17 . The tibial prosthesis system of claim 16 , wherein the tibial tray further comprises a posterior portion and a central axis equidistant between the anterior portion and the posterior portion, and the central aperture extends posteriorly beyond the central axis.
18 . The tibial prosthesis system of claim 16 , wherein, with the clip received in the central aperture, at least a portion of the central aperture remains unobstructed between the bone facing surface and the joint facing surface.
19 . The tibial prosthesis system of claim 16 , further comprising a first stem and a second stem, wherein both the first stem and the second stem are configured to be embedded within a tibia to inhibit movement of the tibial prosthesis system relative to the tibia.
20 . The tibial prosthesis system of claim 16 , wherein the clip comprises an anterior profile configured to align with an anterior edge of the anterior portion of the tibial tray.
