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: 5-Year Follow-Up of a Randomized Controlled Trial.
BACKGROUND Gap balancing ( GB ) has been noted to sacrifice joint-line maintenance to improve gap symmetry . This study aims to determine whether this change affects function or quality of life in the midterm . METHODS A prospect i ve blinded r and omized controlled trial was completed with 103 patients r and omized to measured resection ( n = 52 ) or GB ( n = 51 ) . Primary outcome measured was femoral component rotation . Secondary outcomes measured were joint-line change , gap symmetry , and function and quality -of-life outcomes . RESULTS At 5 years , 83 of 103 patients ( 85 % ) were assessed . There was no significant difference between groups in terms of functional or quality of life outcomes . A subgroup analysis revealed that there was no significant association between those with asymmetrical flexion and /or extension or medial and /or lateral gaps during knee replacement and subsequent functional outcomes . No significant difference was detected with those with an elevated joint line and postoperative function . CONCLUSION In the midterm , the result ant change in joint-line and maintained gap symmetry noted with GB does not result in significant change to function or quality of life
