Presentation
Unilateral knee swelling.
Patient Data
There is extensive synovial thickening with a heterogeneous mass of old blood and hemosiderin internally, involving the entire knee joint associated with complete loss of the articular cartilage, mainly involving the medial joint compartment along with multiple bony erosions and subchondral cysts formation in the distal femur, proximal tibia and patella (knee joint).
Advanced degeneration of both menisci and ligaments seen.
Appearances are of hemophilic arthropathy.
Case Discussion
Given such images of advanced degenerative changes in a 16 year old male with a known history of hemophilia, and the MRI also demonstrating marked synovial hemarthrosis - this is diagnostic of haemophilic arthropathy.
