SURVIVORSHIP AND FUNCTION OF MASSIVE ENDOPROSTHESES USED IN THE MANAGEMENT OF PERI-PROSTHETIC JOINT INFECTIONS AROUND THE HIP AND KNEE

IntroductionThe burden of peri-prosthetic joint infection (PJI) following hip and knee surgery is increasing. Endoprosthetic replacement (EPR) is an option for management of massive bone loss resulting from infection around failed lower limb implants.AimsTo determine clinical outcome of EPRs for treatment of PJI around the hip and knee joint.MethodsThis was a retrospective consecutive case-series of hip and knee EPRs between 2007–2014 in our tertiary unit for the treatment of PJI following complex arthroplasty or fracture fixation. Data recorded included indication for EPR (infected primary/revision arthroplasty, infected non-union/failed osteosynthesis, gross bone loss following native joint infection), number of previous surgeries, and organism identified. Outcome measures included PJI eradication rate (with failure defined as EPR revision, amputation, or being on life-long suppressive antibiotics), complications, implant survival, mortality, and functional outcome (Oxford Hip/Knee Score; OHS/OKS).Resul...
