Abstract

Objective: To find out the angle of distal femoral cut in total knee arthroplasty in a Indian population.

Methods: Radiographs of the lower limbs from 123 patients (104 women and 19 men) were studied, with 165 knees having an indication of total knee arthroplasty. The anatomical axis, and mechanical axis of femur is marked and angle were calculated. The angle of the femoral cut was determined from the meeting point between the femoral anatomical and mechanical axes. The distribution degree of femoral valgus was compared between men and women

Results: The ideal femoral valgus angle ranged from 3 to 9 degrees, with a mean of 6.2 degrees. Comparing men and women, there was no statistically significant difference regarding the ideal femoral valgus

Conclusions: The mean angle between the femoral mechanical and anatomical axes was 6.2 degree. Preoperative coronal alignment and sex had n  influence on the distal femoral cut.
