title: Comparison of early results of hip arthroplasty with the use of BiCONTACT and Antega stem in the treatment of severe coxarthrosis.
abstract: BACKGROUND
  The aim of the study was to compare functional ant radiographic results of treatment with Antega and BiCONTACT stem.
  
  
  METHODS
  There were 174 patients treated with BiCONTACT and 159 with Antega stem (147 men and 186 women). The age of the patients ranged from 47 to 84 years (mean 57.4 years). The follow-up period ranged from 1 to 6 years (mean 2.9 years). Clinical results improved significantly from a mean 39.4 preoperatively to 91 points postoperatively according to Harris scale for all patients. The two groups of patients treated with different type of stems (Antega and BiCONTACT) were statistically similar in terms of age, gender and follow-up. In any of our patients there was no signs of aseptic loosening.
  
  
  CONCLUSIONS
  Comparing both groups, statistically worse clinical results and more painful hips were found in the group treated with Antega stem. The use of both: BiCONTACT and Antega stems for the treatment of severe coxarthrosis gives good and very good results. Although, implantation of Antega stem is more often related to thigh pain, what may compromise final results.
