Fig. 3From: Improved femoral component rotation in advanced genu valgum deformity using computer-assisted measured resection total knee arthroplastyComputed tomography showing measurement of rotation of the femoral component in the axial plane. The femoral rotational (FR) angle was defined as the angle between the surgical epicondylar axis (AA) and the tangent to the posterior femoral condyles of the femoral component (BB).
