The EKA Femoral Rotation Focus Group has not identified a single best reference method to determine femoral component rotation , but surgeons mostly prefer the measured resection technique using at least two l and marks for cross-checking the rotation .
Malrotation of the femoral component after primary total knee arthroplasty ( TKA ) is one of the most important problems leading to painful TKA requiring revision surgery .
A comprehensive systematic review of the literature was performed to present current evidence on how to optimally place the femoral component in TKA .
Measured Resection versus Gap Balancing Technique for Femoral Rotational Alignment: A Prospective Study
Purpose . To compare the measured resection technique and the gap balancing technique for correction of the femoral rotational alignment . Methods . 57 women and 6 men ( mean age , 70 years ) with end-stage osteoarthritis and ±15 ° malalignment and ±10 ° flexion contracture of the knee underwent primary total knee arthroplasty through the medial approach using the measured resection technique ( n=34 ) or the gap balancing technique ( n=29 ) . Femoral rotational alignment was evaluated before and 7 days after surgery using computed tomography by referencing the 2 posterior condyles to the transepicondylar axis . Results . The 2 groups did not differ significantly in terms of correction of the femoral rotational alignment ( 3.4 ° ±1.4 ° vs. 3.5 ° ±3.1 ° , p=0.817 ) . Conclusion . The measured resection and the gap balancing techniques  achieved comparable correction of femoral rotational alignment
