Object numberGC.11254
TitleKnee joint showing osteoarthritis
Creator Walter (1890-1971) Mercer
DescriptionDry specimen in a glass jar.
Left knee joint showing advanced osteoarthritic changes.
The articular surface of the femur shows that the cartilage is cracked in many places and in the central zone is wider and apparently thinner than normal. At the margin of the articular surfaces a rim of new bone has formed, broadening the articular surface and then rolling downwards and away from the joint. The patella shares the arthritic changes and it too has a margin of new bone formation.
