The ankle is one of the most frequent joint affected by haemophilia, in the second decade of life it can be considered as the most common site for haemophilic arthropathy. The aim of this study is to evaluate the results of 15 surgical interventions of the hindfoot performed on 11 patients. Twenty-seven of 70 male patients suffering from haemophilia were treated for haemophilic arthropathy of the hindfoot. We performed 15 operations on 11 patients with a mean age of 33.5 (range: 10-53) years. The surgical treatment consisted of 15 operations, 12 of which concerned the talocrural joint (six synovectomies, three radiosynoviorthesis, four arthrodeses, one achilles tendon lengthening) and one the talocalcaneonavicular joint (one triplearthrodesis). The arthrodeses of the talocrural joint were undertaken by screw, the triplearthrodesis by clamp fixation. The synovectomies were all late synovectomies and performed by open means. The mean follow-up period was 32.0 (range: 12-84) months. The mean age at surgery was 29.6 (range: 8-51) years. No perioperative complications were registered when adequate replacement therapy was carried out. The consolidation of the arthrodeses was accomplished within 8-12 weeks. All synovectomies stopped or reduced significantly recurrent joint bleeding. With both procedures we achieved pain relief and walking ability improvement. The aim of synovectomy is to reduce bleeding episodes. If synovectomy can halt the progression of the haemophilic arthropathy is controversially discussed, especially when surgery was carried out in the presence of an established arthropathy. If synovectomy fails, the arthrodesis proves to be a good treatment option.
