title: Experiences with Bicontact ceramic-ceramic total hip arthroplasty.
abstract: OBJECTIVE
  Mid-term result documentation of ceramic-on-ceramic cementless total hip replacement.
  
  
  METHODS
  From November 1998 to December 2005, 356 patients were submitted to 419 total hip arthroplasties of the hip with a cementless, ceramic-ceramic Bicontact/Plasmacup type of prosthesis. Patients were controlled in a consecutive prospective study.
  
  
  RESULTS
  The average age of the patient group is 47.9 years, with an average follow-up of 48 months. There was no case with release of osteolysis of the acetabular or femoral components. There was one ceramic head fracture in an obese patient. Articular wear was negligible and could not be measured radiographically.
  
  
  CONCLUSIONS
  The ceramic-ceramic Bicontact hip joint replacement presents a low complication rate in young patients, with very low wear.
