Overview

An x-ray of the joints in the case of hemophilic arthropathy may be helpful in the diagnosis of hemophilia. Pettersson scoring system, designed in 1980, is widely applied for the classification of osteochondral changes of hemophilic arthropathy in elbows, knees, and ankles. This scoring system is based on typical findings of hemophilic arthropathy on posterior-anterior and lateral x-rays.

Classification of hemophilic arthropathy according to the Pettersson score

Finding	Interpretation
Osteoporosis	Absent = 0 Present = 1
Enlargement of epiphysis	Absent = 0 Present = 1
Irregularity of subchondral surface	Absent = 0 Partially involved = 1 Totally involved = 2
Narrowing of joint space	Absent = 0 Joint space > 1 mm = 1 Joint space < 1 mm = 2
Subchondral cysts formation	Absent = 0 1 cyst = 1 >1 cyst = 2
Erosion of joint margins	Absent = 0 Present = 1
Gross incongruence of articulating bone ends	Absent = 0 Slight = 1 Pronounced = 2
Joint deformity (angulation and/or displacement)	Absent = 0 Slight = 1 Pronounced = 2
