a AAEP scale 0–5
b 0 = no effusion, 1 = mild, 2 = moderate, 3 = severe effusion, 4 = severe swelling of the metacarpal joint region
c 0 = no increase, 1 = slight increase, 2 = moderate increase, 3 = considerable increase in baseline lameness, 4 = non-weight-bearing lameness
d 0 = no pain at flexion, 1 = mild pain, 2 = moderate pain, 3 = severe pain
