Abstract: Hip arthroplasty is one of the most promising orthopaedic procedures and has improved pain and improved hip function in patients worldwide. Despite the success of modern designs and bearing surfaces, around 10 % of hip arthroplasty still fail within 10 years. Improvements in surgical technique and prosthesis design have decreased the incidence of deep infection, dislocation and fracture, however aseptic loosening, the clinical end point of osteolysis, remains the most frequent complication. Prosthesis loosening results in pain and disability, requiring revision surgery. Revision hip arthroplasty is associated with a 3 to 8-fold greater in-hospital mortality, poorer functional outcome, longer hospital stay, and higher cost than primary surgery.
