Is There a Force Target That Predicts Early Patient-reported Outcomes After Kinematically Aligned TKA?

CONCLUSIONS: Tibial compartment forces comparable to those reported for the native knee and insufficient sensitivity of the Oxford Knee and WOMAC scores might explain why mechanical alignment force targets were not useful and a force target was not identified for kinematic alignment. Intraoperative sensors may allow surgeons to measure forces very precisely in the operating room, but that level of precision is not called for to achieve a good/excellent result after calipered kinematically aligned TKA, and so its use may simply add expense and time but does not improve the results from the patient's viewpoint.
LEVEL OF EVIDENCE: Level III, therapeutic study.
