A metal artifact composed of two separate components: an upper “femoral” component and a lower “tibial” component. These components are similar to 2023.JAC.275, but with each component divided in half.
The femoral component is a curved shape corresponding to the shape of one compartment of the femur joint. Its outer surface is highly polished. Its inner surface is textured. Much of this textured surface is coated in a dried adhesive that is off-white in colour . Two studs protrude from this textured surface.
The tibial component consists of a flattened pad with a off-white plastic insert comprising its upper surface. An angled, pointed stud protrudes from its base. art of this textured surface is coated in a dried adhesive that is off-white in colour. The plastic pad has been very heavily damaged by wear.
Accession Number: 2023.JAC.276
Primary Materials: Metal, Plastic
Marked in black on one side of the curve: “K98E192// #9L MED// [unidentified logo symbol]c”
Marked in black on one side of the curve: “#9 LM/RL// [unidentified logo symbol]c// T98K528// 4020-009L”
Femoral Component: Height = 3, Width = 1.5, Length = 5.5; Tibial Component: Height = 2, Width = 2.5, Length = 5.
The knee replacement was introduced to address a number of knee ailments, especially severe arthritis. Partial knee replacement is used in cases in which damage is largely confined to one compartment of the knee.
The metal parts of both components are in good cosmetic condition. The mating surfaces of both components are partly covered in a glue adhesive. The plastic insert of the tibial component has been entirely worn through to the point that the patient would have experienced metal-on-metal contact between the implants.
Date of Manufacture: Late 20th c.
The Robert W. Jackson Arthroscopy Collection was acquired by the University of Toronto from Dr. Jackson’s family on November 12th, 2020.
This artifact was obtained in two Ziplock parts bags, stapled together, that were marked with patient information. These bags have been discarded and the artifact placed in two unmarked bags.
