Prevention and treatment of knee problems in children with spina bifida.

The outcome of surgical treatment of flexion, valgus or extension knee deformities is reviewed in 114 spina-bifida children (164 knees) who received such treatment over the period 1968 to 1975. Eggers' procedure for 26 knees produced very good results in 21 cases and good results in four; supracondylar osteotomy in 128 knees produced very good results in 104 cases and good results in 16; and quadriceps Z-plasty with anterior capsulotomy in 10 knees produced very good results in nine cases.
