Health Sciences · Robert W. Jackson Arthroscopy
A metal artifact composed of two interlocked components connected by a ball joint, or rotating knee hinge (RKH). The upper portion (“femoral component”) has a shorter stem than the lower “tibial component”. The surface of the femoral component is cushioned by two mirrored plastic pads where it meets the tibial component. At the centre of the femoral component is the ball portion of the ball joint.
The socket portion of the ball joint forms the top portion of the tibial component. This is lined by a plastic cup that cushions the ball portion of the femoral component. The curved upper surface of the tibial component has a mirror finish.
Accession Number: 2023.JAC.274
Alternative Name:
Primary Materials: Metal Plastic
Femoral Component:
Stamped into the surface of the femoral component from which the ball protrudes: “EBRT”
Stamped into one of the short sides of that surface: “FRONT”
Stamped into another of the short sides of that surface: “EBRTA”
Stamped into another of the short sides of that surface: “6657-1-900”
Tibial Component:
Stamped into one side of the socket joint portion: “FDJC”
Lightly stamped or engraved into one side of the long stem: “2658-5-906 FDJCAC 6[n]STEM LEFT” This is followed by a stylized “V” symbol
Dimensions (cm): Height = 24.5, Width = 6.5, Legth = 6.5
The total knee replacement was introduced to address a number of knee ailments, especially severe arthritis.
This is an constrained knee replacement, meaning that there is a hinge between the femoral and tibial component.
This artifact is in good cosmetic condition. Certain areas , such as the edge of the curved upper surface of the tibial component, are noticeably damaged, possibly during the extraction process. Areas of the plastic pads are noticeably damaged. There is a pale deposit on areas of the tibial component.
