title: [Results of surgical therapy of knee flexion contractures in patients with myelomeningocele].
abstract: This study reports the results of 98 operations for correcting knee-flexion-contractures, which were performed between 1972 and 1989 in 60 patients with myelomeningocele. 13 knees had hamstring lengthening and 85 knees had radical flexor release. In 4 patients, who had flexion-contractures of more than 50 degrees, the soft tissue release was combined with supracondylar extension osteotomy. 58 patients had additional hip-flexion-contractures and 39 patients had feet deformities. The average age at time of surgery was 8 years, 3 months. The average follow-up-period was 65 months with a minimum of 1 year and a maximum of 13 years. In 92 knees a permanent extension ability could be achieved. In 6 knees a recurrence of flexion-contracture occurred making a second surgery necessary. The main problem in the postoperative period were 13 skin necroses, which were seen mainly after an s-shaped incision. As a conclusion a perpendicular midline incision is recommended. After surgery 11 patients could be provided for the first time with an orthoses. In the remaining the upright body position or the erection of the orthoses could be improved.
