Résumé
Twenty-five consecutive patients with advanced Osteoarthritis of the knee with different degrees of varus deformities, were treated by Total Knee Replacement [TKR] at EI-Zahra and EI-Helal Hospitals. All patients were available for clinical and radiographic evaluation by the knee society scoring system. The mean follow up period was 21 months [range 3 months to 4 years]. The maximum varus deformity was 22°; the minimum was 7° with a mean value of 14.7°. At the latest follow-up examination, the mean knee score improved from 23.6 to 97.6 points and the mean functional score improved from 40.9 to 64.1 points. Full correction to 5° -10° valgus was achieved in 88% of cases. No major complications were encountered in this series. We can conclude that arthroplasty of the knee is an effective operative treatment for patients with OA associated with varus deformity of the knee
