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 .
Gap balancing sacrifices joint-line maintenance to improve gap symmetry: a randomized controlled trial comparing gap balancing and measured resection.
A total knee arthroplasty can be completed using two techniques ; measured resection or gap balancing . A prospect i ve blinded r and omized controlled trial was completed with 103 patients r and omized to measured resection ( n = 52 ) or gap balancing ( n = 51 ) . Primary outcome measure was femoral component rotation . Secondary outcome measures were joint-line change , gap symmetry and function and quality -of-life outcomes .  Gap balancing result ed in a significantly raised joint-line compared to measured resection .  Gap symmetry was significantly better using gap balancing .  Functional outcomes and quality -of-life were not significantly different at 24 months . Using computer navigation , gap balancing significantly raises the joint-line in order to improve gap symmetry . This does not result in a clinical difference in function or quality of life at 24 months
