Abstract
Severe deformity of the distal femur due to malunited fracture in a poliomyelitis patient is a rare entity. No reports are available in the literature about the results of total knee arthroplasty (TKA) in such cases. We report a 4-year follow-up of TKA in a 52-year-old woman who had postpoliomyelitis syndrome with malunited distal femur fracture associated with severe deformity and degenerative arthritis. TKA in poliomyelitis patients could reveal a good short-term functional improvement. We aim to demonstrate that even with the presence of deformity from previous trauma in polio cases, TKA would improve functional abilities. However, long-term follow-up is needed for similar cases.
