Reconstruction Using Hinged Knee Replacement of an Unusual Knee Deformity as a Sequelae of Paediatric Septic Arthritis: A Case Report.

Patients with osteoarticular infections may have initial complications secondary to bacteraemia and late complications related to bone alterations due to infection. We present a case of a 28-year-old man with a complex deformity of his left knee as a sequelae of septic arthritis, varus with concave deformity of the lateral tibial plateau, and bony deficiency in the medial compartment. We describe how a hinged knee replacement was undertaken to deal with an unusual deformity and improve patient symptoms and function.
