Total knee replacement for correction of severe post-traumatic deformity

Abstract

Distal femur and proximal tibial fractures are relatively common in young and elderly patients, which can lead to malpositioned union. Management of these genu valgumknee deformities is challenging for the orthopedist. The clinical case of a 67-year-old male patient is presented who, 24 years earlier, suffered a fracture of the distal femur and left proximal tibia treated with open osteosynthesis. He presented knee pain that made deambulation difficult. A large valgus deformity was evidenced, with external rotation, flexion ranges of 40° and extension of minus 20°. A rotational hinge-type prosthesis was placed in a single surgical time, the axes and deformity were corrected, with good clinical and radiological results. Flexion of 80° and extension of minus 5° at 30 days postoperative. Therefore, it is recommended to carry out a meticulous study of the patient, individualizing each case as unique and to carry out pre-surgical planning in these unusual cases of deformity.
