Results of total hip replacement (THR) performed in 23 patients (9 male and 14 female) aged from 13 to 18 years with coxarthrosis on the background of juvenile rheumatoid arthritis (JRA) are presented. All patients have been operated on at traumatologic-orthopaedic department of Scientific Center for Children's Health during the period from 2008 to 2012. Main complaints of patients were pain and limitation of movement in hip joints, discrepancy of lower extremities length, claudication, disturbance of weight bearing ability and lower extremities function that in 90% of cases made the movement without additional support impossible. Indications to THR and peculiarities of surgery in young patients with JRA are described. Almost in all patients correction of lower extremities deformity and formation of either normal or close to normal functional status have been achieved. Roentgenologic examination showed good localization of implant components.
