title: Long-term survivorship analysis of cemented total hip replacement (THR) after avascular necrosis of the femoral head in renal transplant recipients.
abstract: BACKGROUND
  We studied the long-term survival and the rate of revision of 93 consecutive total hip replacements (THRs) performed for avascular necrosis of the femoral head after renal transplantation from 1971 to 1988. Seventy-four were primary procedures while 19 hips had undergone previous surgery procedures on the same hip in the form of other conservative options.
  
  
  METHODS
  The patients of mean age of 38 years were analysed by the Kaplan-Meier method with revision for any reason as the end-point. The follow-up period averaged 216 months (range 1-332).
  
  
  RESULTS
  Thirteen hips were revised while 26 patients (36 hips) died during the follow-up period. The cumulative survival of the implant was 98.8% at 10 years and 63.8% at 20 years.
  
  
  CONCLUSIONS
  Cemented THR performed after renal transplantation is satisfactory and, at least for the first 10 post-operative years, the results are equivalent to those obtained in the general population with primary osteoarthritis.
