Discussion

Did you notice the giant vastus medialis ? Its actually a massively distended joint effusion, seen enveloping the distal thigh (see MRI). The severe joint space loss, out of proportion to typical features of osteoarthritis (sclerosis, phytosis), is a clue. This is a patient with rheumatoid arthritis with exuberant synovial proliferation.
