title: Extensor supracondylar femoral osteotomy as treatment for flexed haemophilic knee.
abstract: The experience with extensor supracondylar femoral osteotomy as treatment for the flexed haemophilic knee is presented with the description of 19 patients treated during a 30-year period (1968-98). The average age of the patients was 16 (8-35 years), and the average age follow-up was 13 years (3-30 years). Six patients had flexion fixed deformity while the rest presented 40 degrees average range of motion (10-75 degrees). In 13 patients a single osteotomy without internal fixation was performed, in one an osteosynthesis with a condylar plate and in five stabilization was achieved by means of Blount staples. Previous surgery was performed in two patients with patello-femoral ankylosis. The osteotomy site was consolidated in every patient and the deformity was corrected. Two bleeding complications were observed: one haemarthrosis and one psoas haematoma. Flexion relapsed in one patient who underwent another procedure after 12 years. One patient presented with a peroneal nerve paralysis; another one a genu recurvartum; which required flexor osteotomy. The extensor supracondylar femoral osteotomy is a procedure that aligns the limb with scarce modification of articular mobility.
