Tibial knee component with a mobile bearing |
摘要 |
A mobile bearing knee prosthesis apparatus includes a tibial plate. The tibial plate includes a medial lobe and a lateral lobe conjoined in a dividing plane. The apparatus further includes a tibio-femoral insert and a stud-like protuberance extending from the tibial plate into the tibio-femoral insert. The stud-like protuberance includes a protuberance sidewall positioned in the tibio-femoral insert. The protuberance sidewall is bisected by the dividing plane and includes a pair of opposing eccentric convex arcuate portions, and the tibio-femoral insert is moveable relative to the tibial plate about an axis medially disposed from the dividing plane. A mobile bearing knee prosthesis apparatus includes a tibial plate and a tibio-femoral insert coupled to the tibial plate. The tibio-femoral insert includes a generally posteriorly positioned chamfered superior surface and defines a generally posteriorly positioned generally U-shaped space bounded at least in part by the chamfered surface.
