LONG-TERM (>20 YEARS) FOLLOW-UP OF EXETER CEMENTED HIP ARTHROPLASTY IN PATIENTS 50 YEARS AND UNDER

IntroductionThere is sparse evidence regarding the survivorship beyond 20 years of both uncemented and cemented hip replacements in patients 50 years and under. We report a unique series reviewing 20–26 year follow-up of patients ≤50 years with cemented Exeter THR.Materials and MethodsWe reviewed the survivorship with clinical and radiological outcomes of 138 consecutive cemented THR's in 113 patients ≤50 years. The pre-op diagnoses included Osteoarthritis (30%), DDH (25%), RA (9%) and Post traumatic OA (5%), and 31% of patients had previous surgery to the hip. All patients were followed up at 5 year intervals and there was no patient lost to follow up.ResultsMean age of the patients at the time of surgery was 41.6 (18–50) years. Mean follow up time was 21.6 (20–26) years. There were 93 survivors and 14 deceased patients, with 31 patients needing revision THR. The reasons for revision surgery included 28 cases revised for aseptic loosening of the cup, one patient with Gaucher's disease who developed local...
