The degree of haemophilic osteoarthropathy was assessed by the Pettersson-score in 219 knees, elbows and ankles of 40 children and adolescents suffering from haemophilia. 55.3% of the joints were unaffected and only 8 joints showed score values greater than 8. Enlargement of epiphyses (36.1%) and irregular subchondral surface (32.9%) were the most frequent observations, while osteoporosis (5.4%) was only rarely observed. Haemophilic osteoarthropathy was most severe in the ankles, while the knees were only moderately affected. Among 11 patients 493 bleedings into 61 joints were observed during a four-year period. If the bleedings recurred, more than 3 bleedings per year always resulted in haemophilic osteoarthropathy.
采用Pettersson评分法评估40例血友病儿童和青少年的219个膝关节、肘关节和踝关节的血友病性骨关节炎程度。55.3%的关节未受影响，只有8个关节的评分值大于8。骨骺增大（36.1%）和软骨下表面不规则（32.9%）是最常见的表现，而骨质疏松（5.4%）则很少见。血友病性骨关节炎在踝关节最为严重，而膝关节仅中度受累。在11例患者中，在四年期间观察到61个关节发生493次出血。如果出血复发，每年超过3次出血总是会导致血友病性骨关节炎。
