title: Total knee arthroplasty with application of anatomic endoprosthesis journey. Clinical and radiological assessment in a 2-year follow-up.
abstract: BACKGROUND
  Growing expectations regarding TKA inspire the researchers to look for a perfect endoprosthesis. One of the new-generation prostheses is Journey BCS (Smith&Nephew), introduced in 2004, which, according to its inventors, completely restores anatomy and kinematics of the knee. The aim of this study was to evaluate TKA with Journey endoprosthesis in a two-year follow-up.
  
  
  METHODS
  The study was a prospective analysis. It included 61 patients aged 52-87 years, with primary OA and axial deformity under 15°, and without a significant instability in the frontal plain. A total of 61 TKAs were assessed with the use of WOMAC OI, KSS clinical and radiological scales. The group was evaluated after 6, 12, 24 weeks, 1 and 2 years postoperatively.
  
  
  RESULTS
  At the end point of observation, 97% of the patients obtained good and very good clinical and radiological results. Mean knee flexion in the study group increased until 24 week and reached 121.8°. These results are comparable with the results described in the literature, but do not differ significantly from the outcomes of conventional endoprostheses.
  
  
  CONCLUSIONS
  In the presented material, TKA with the application of anatomic endoprosthesis Journey allowed to obtain in the majority of patients very good and good early clinical and radiological results.
