Knee prosthesis assembly with ligament link

1. A prosthetic knee joint assembly for a knee joint of a patient with a tibia, and a femur, the prosthetic knee joint assembly comprising:

a unitary, single body femoral component that is adapted to engage the femur, the femoral component including an articulating surface;

a ligament link;

at least one bearing that supports articulation of the articulating surface of the femoral component thereon;

a tibial tray that is adapted to engage the tibia and that supports the at least one bearing;

a ligament link coupling component that is included directly on the femoral component, the ligament link coupling component operable to couple to the ligament link to couple the ligament link to the femoral component; and

a first opening and a second opening included anteriorly on the tibial tray, the ligament link extending from the femoral component, bypassing the at least one bearing, and received in one of the first opening and the second opening to bypass the tibial tray to operably couple to the tibia, the first and second openings being disposed on opposite sides of a medial plane of the tibial tray,

wherein the femoral component includes a medial condyle portion and a lateral condyle portion joined by a patellar track portion, an intercondylar opening being defined between the medial and lateral condyle portions, the femoral component also including a wall that extends superiorly from one of the medial condyle portion and lateral condyle portion, the ligament link coupling component extending from the wall into the intercondylar opening.

2. The prosthetic knee joint assembly of claim 1 , wherein the ligament link includes at least one of an autograft, an allograft, a xenograft, an artificial graft, and combinations thereof.

3. The prosthetic knee joint assembly of claim 1 , wherein the ligament link extends from a first end to a second end and includes an outer wall that defines an interior longitudinal passage portion disposed between the first and second ends, the ligament link including a first aperture extending through the outer wall and disposed between the first and second ends, the ligament link also including a second aperture extending through the outer wall and disposed between the first and second ends, the first end extending through the first and second apertures and the longitudinal passage portion to define a first adjustable loop, the second end extending through the first and second apertures and the longitudinal passage portion to define a second adjustable loop.

4. The prosthetic knee joint assembly of claim 1 , wherein the wall is a first wall extending superiorly from the medial condyle portion, the femoral component including a second wall that extends superiorly from the lateral condyle portion, the ligament link coupling component fixed directly to both the first wall and the second wall and extending through the intercondylar opening.

5. The prosthetic knee joint assembly of claim 1 , wherein the first opening and the second opening are each a through hole extending through the tibial tray.

6. The prosthetic knee joint assembly of claim 5 , wherein the tibial tray includes a superior surface and an inferior surface, and wherein the through hole extends through both the superior surface and the inferior surface.

7. The prosthetic knee joint assembly of claim 5 , wherein an axis of the through hole is disposed at an acute angle relative to the medial plane of the tibial tray.

8. The prosthetic knee joint assembly of claim 5 , wherein an axis of the through hole is disposed at an acute angle relative to a coronal plane of the tibial tray.

9. The prosthetic knee joint assembly of claim 1 , wherein the at least one bearing includes a bearing opening, the ligament link adapted to be received in the bearing opening to bypass the bearing.
