Abstract :A 72-year-old patient who had metal-on-metal insert ignore into journalissuearticles values(MMO); total hip arthroplasty insert ignore into journalissuearticles values(THA); 7 years ago has developed a gluteal mass and pain. Plain radiographs showed a well-fixed THA on the left side with an increased acetabular inclination. Needle aspiration of the mass showed “milky stained” highly viscous liquid. After the approval of the patient, a revision total hip arthroplasty had been performed. There were severe necrosis and granulomatous type reactions all around the hip and the components. After extensive debridement, all the components were removed and a long-stemmed revision total hip arthroplasty with polyethylene insert was performed. We think that patients with MMO THA must be carefully reviewed after the surgery even if they are asymptomatic.
