Results of XXXX on excessive genu varum superior to 20  .

@entity1 @entity348 @entity625
BACKGROUND: Total knee arthroplasty on excessive genu varum is a more demanding technique and gives worst results than procedures on moderate deformations. It remains a subject of controversies due to the lack of consensus. The purpose of our study is to evaluate the results of @entity348 ( @entity348 ) on excessive genu varum (superior to 20  ) by analyzing pre and post operative clinical and radiological parameters. METHODS: We reviewed retrospectively 40 @entity348 in 33 @entity1 (seven @entity1 operated bilaterally) performed for genu varum superior to 20   between 2004 and 2011. Pre and post operative evaluation of @entity1 were done according to the International Knee Society score. RESULTS: The mean age of our @entity1 was 67 years with a female predominance. Tricompartmental @entity625 was the etiology in all cases. Pre operative IKS score and HKA angle were respectively 52,36 /200 points and 155,7  . The mean follow up was 4 years. Our results were generally satisfactory. The post operative IKS score was 155,36 points (mean joint score of 85.85 points and mean functional score of 69.26 Points) and the post operative HKA angle was 176,17  . Only 60   of @entity1 had normal HKA angle. We noted aseptic loosening of the tibial component in 3 cases. CONCLUSION: @entity348 on excessive genu varum is more demanding technique. Pre operative planning after analyzing different clinical and radiological parameters is necessary to obtain a good functional outcome while minimizing the rate of complications.
