The
Components used for Total Knee
Replacement Surgery 2
The
femoral component
This attaches to the
thigh bone. The surface is as perfectly smooth as possible
and is made from cobalt chrome alloy.
|
The
femoral component
The underside is
"porous coated" for the bone to grow into the
component, to lock it into position.
|
The
tibial component
This consists of a metal base plate (porous
coated on the underside) and a rotating
Ultra High Molecular Weight
PolyEthylene (UHMWPE)
insert.
|
 The
tibial component is smooth on its top surface to allow the
polyethylene insert to rotate freely |
 |
 |
The patella component is
like a button. It is smooth where it articulates with the
femoral component. It has posts to help lock into the bone and is
cemented
into position.
Sawbones have been
developed specifically for use in exercises where a realistic
bone specimen is required to provide a working model for various
orthopaedic operations.
