Femoral corrective osteotomy for management of knee deformities in poliomyelitis.

V-shaped femoral osteotomy used by Aglietti in 1987 to treat lateral unicompartmental knee osteoarthritis associated with valgus deformity did not achieve good results because of immobilizing an arthritic knee in plaster of Paris cast for a long period. Modified Agliettis method was used in twelve patients arranged in age from 16 to 25 years; their knee deformities were due to poliomyelitis, traumatic or developmental. The advantages of this technique are limb length is preserved, correction of deformities in more than one plane is possible, faster healing due to wide surface area and impaction, no internal fixation, no second surgery to remove implants, alignments can be adjusted postoperative, and the osteotomy is stable without fixation
