title: Cementless total hip arthroplasty with BiCONTACT stem - go od results at long term of follow -up.
abstract: BACKGROUND
  The aim of our study was an evaluation of long-term clinical and radiological results of arthroplasty with BiCONTACT stem.
  
  
  METHODS
  We qualified 115 patients (125 hips) to the retrospective analysis with a minimum 10-year follow-up period. The mean age of patients on the day of surgery varied was 50.7 years. The follow-up period lasted from 126 to 199 months (mean 14 years).
  
  
  RESULTS
  Harris hip score increased from 47.1 before operations to 85.3 at the last follow-up. Excellent results were recorded in 81 (64.8%) cases, good results in 23 (18.4%) and satisfactory results in 10 (8%) cases, while failure was noted in 11 cases. In 2 cases, aseptic stem loosening was identified, in 8 cup and in 2 cases both: cup and stem loosening. The BiCONTACT stem survival, assessed with the Kaplan-Meier estimator was 97.6%, while that of the both: cup and stem amounted to 91.2%, having taken into account acetabulum or stem loosening as end-point, regardless of cause.
  
  
  CONCLUSIONS
  1. In an average 14-year observations, application of a BiCONTACT stem gives good clinical results. 2. With no incidental complications and proper operative technique, the risk of aseptic loosening is really scarce.
