Method of implanting a prosthetic knee joint assembly

摘要

A prosthetic knee joint assembly includes a femoral component that engages a femur and at least one bearing that supports articulation of the femoral component thereon. Also, the assembly includes a tibial tray that engages a tibia and that supports the bearing. A ligament link coupling component is included on the femoral component or the tibial tray. The ligament link coupling component is operable to couple to a ligament link to couple the ligament link to the femoral component or the tibial tray. Moreover, the assembly includes an opening included on the other of the femoral component or the tibial tray. The ligament link is received in the opening to bypass the other of the femoral component or the tibial tray to operably couple to the respective one of the femur or the tibia.

主权项

1. A method of implanting a prosthetic knee joint assembly comprising:
selecting for implantation a ligament link from a plurality of ligament links; engaging a femoral component to a femur; engaging a tibial tray to a tibia; intraoperatively choosing whether to operably couple the selected ligament link to one of the femur or the tibia; operably coupling the selected ligament link to the one of the femur or the tibia; extending the selected ligament link through an opening of one of the femoral component or the tibial tray, the one of the femoral component or the tibial tray operable to engage to the one of the femur or the tibia; operably coupling the selected ligament link to a coupling component of the other of the femoral component or the tibial tray; and selecting the coupling component from a plurality of coupling components disposed on the tibial tray, and wherein operably coupling the selected ligament link to the coupling component includes operably coupling the selected ligament link to the selected coupling component; wherein selecting the coupling component from the plurality of coupling components includes determining whether the prosthetic knee joint assembly is for a left knee or a right knee and selecting the coupling component corresponding to the determined one of the left knee and the right knee.
