Abstract
A total knee replacement prosthesis (TKR) is provided in which a pintle hinge enables the knee to pivot about a horizontal axis. A degree of rotational movement about a vertical axis is provided by fabricating the tibial component in at least two parts. One part is attached to the hinge and includes a stem portion which is designed to be rotatable with a hollow shell adapted to be fixed into the tibia. The hinge portion is standardized and is designed to receive femoral and tibial stem portions having dimensions to suit a particular patient.
