title: Long-term results of total knee arthroplasty following high tibial osteotomy according to Wagner.
abstract: OBJECTIVE
  There is relatively little information available about the long-term results of total knee arthroplasty (TKA) following high tibial osteotomy. The aim of our study was to share our experiences and long-term results of TKA after a previous closing wedge high tibial osteotomy according to Wagner.
  
  
  METHODS
  In a retrospective study we identified 48 consecutive patients who had undergone TKA after a previous closing wedge high tibial osteotomy according to Wagner with a follow-up of over ten years. The average duration of follow-up after the TKA was 13.3 years (min 10.0, max 15.5). X-rays were taken in two planes before TKA, one week after TKA and at the latest follow-up. Tibio-femoral alignment was measured on weightbearing long-leg anteroposterior radiographs. Radiolucent lines at the latest follow-up were documented. Functional evaluations were performed preoperatively and postoperatively (at the time of latest follow-up).
  
  
  RESULTS
  The mean Knee Society function score increased from 63.1 points preoperatively to 90.0 points postoperatively. The mean overall Knee Society score increased from 93.2 points preoperatively to 160.8 points postoperatively. The mean average femoro-tibial angle was corrected from varus 0.8° (varus 14°-valgus 8.0°) preoperatively to valgus 7.6° (valgus 2-9°) at the last follow-up.
  
  
  CONCLUSIONS
  The closing wedge high tibial osteotomy according to Wagner does not compromise subsequent total knee replacement and leads to good clinical and radiological results.
