Orthopaedics · Joints: haemophilic arthropathy
Sample itemWhich joints are most frequently involved by haemarthrosis in haemophilia?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Knee, elbow and ankle
Recurrent bleeding into the knee, elbow and ankle causes synovial hypertrophy with haemosiderin deposition, cartilage destruction and secondary arthritis. Prophylactic factor replacement prevents this arthropathy, and radiosynovectomy treats chronic synovitis.
Option by option
A. Shoulder and wrist
The shoulder and wrist are less often affected.
B. Knee, elbow and ankle (correct)
Correct. The knee, elbow and ankle are the commonest.
C. Sacroiliac and spinal joints
Axial joints are rarely affected.
D. Small joints of the hands
Small hand joints are not typical.
