Amniotic arthroplasty for tuberculosis of the hip. A preliminary clinical study

Abstract

Arthroplasty of the hip using an interposed multi-layered cap of amniotic membrane is reported in 28 patients with tuberculous arthritis. The disease had been present from one to seven years, and five patients had multiple discharging sinuses. Follow-up was from 30 to 46 months. Amniotic tissue caused no inflammatory reaction, or obvious rejection, and 25 patients were free of symptoms, with a good range of movement and a stable joint. The three failures were caused by dislocation, fracture of the femoral neck and extra-articular bone formation respectively. Amniotic arthroplasty seems to be capable of providing a painless, mobile and stable joint in patients with tuberculosis of the hip.
