Modular cementless total hip arthroplasty for hip infection sequelae.

Childhood hip infection may produce significant anatomical deformations leading to the premature onset of secondary osteoarthritis. Total hip arthroplasty (THA) in these patient populations can be technically challenging and has been associated with high complication rates. This article reports the results of 58 cementless THAs with use of a modern implant design. The complication rate, including one recurrent infection, was relatively low. Cementless THA with use of a modular stem coupled with a metal-backed socket was found to be an effective and reliable treatment option for patients with the late sequelae of infective hip arthritis.
