Revision Total Hip Arthroplasty: Indications and Contraindications
The term indications carries a sense of certainty rarely present in surgical scenarios. Particularly in revision surgery, indications represent the end point of a complex decision-making process that involves both the surgeon and the patient. Currently, the most common indications for revision total hip arthroplasty (THA) in the United States are recurrent instability, aseptic implant loosening, and periprosthetic joint infection. Other common reasons for revision surgery are osteolysis, bearing surface wear, and periprosthetic fracture. Recently, an increasing number of patients seek treatment for failed implants, recalled implants, or pain secondary to metal-on-metal bearings and corrosion-related problems. Familiarity with the nuances of these diagnoses is critical for surgeons who perform revision THA.
