Total knee replacement (TKR) is most commonly caused by osteoarthritis of the knee, and can result in loss of articular cartilage, subchondral bone sclerosis, bone spurs and degenerative subchondral cysts
2]-weighted and STIR sequences were evaluated as subchondral cysts
4-6) Typical plain radiograph findings of hemophilic knee arthropathy include a widened intercondylar notch, squaring of the patella, joint space narrowing, subchondral cysts
, osteoporosis, and accelerated degenerative changes.
On the other hand, diagnoses specific to older patients include metastasis, multiple myeloma, enchondroma, and subchondral cysts
Intraosseous ganglia when associated with osteoarthrosis may be difficult to divorce from large subchondral cysts
Classic radiographic features "are focal joint space narrowing, osteophyte, subchondral bone sclerosis, and subchondral cysts
form as synovial fluid is forced beneath the joint surface.
Because synovial fluid is toxic to bone marrow, subchondral cysts
form if the defect extends to the subchondral bone surface.
Another theory is the formation of cavitation within the trabecular bone similar to the formation of subchondral cysts
as a result of pumping of the synovial fluid to subchondral BM through the cartilage and bone defects.
can be packed with bone graft to support overlying healthy articular cartilage.
Radiographic findings at this stage may include joint space narrowing, osseous erosions, subchondral cysts
, sclerosis, and osteophytosis.
were noted to involve the bilateral capitates, the left hamate, and the right scaphoid.
