【 摘 要 】

Objective:to review the medical files of 19 patients with a diagnosis of amyoplasia, who underwent percutaneous extensor osteotomy of the distal femur to correct deformities in whom the knees were fixed in flexion.Methods:we analyzed 37 osteotomy procedures on 35 knees that presented an initial deformity in which the knees were fixed in flexion at 33.8°. All of these knees underwent percutaneous extensor osteotomy of the distal femur and were followed up for a mean period of 73.7 months.Results:we observed recurrence of the deformity in 29 osteotomy cases, i.e. in 78.4% of them. The mean recurrence velocity of the deformity was 0.69°/month.Conclusion:percutaneous extensor osteotomy of the distal femur provided sufficient correction of deformities in which the knee was fixed in flexion in these amyoplasia cases, but there was a significant degree of recurrence among the patients analyzed.
