Excerpt

For many years, there had been little argument about how to align a TKA: Put the center of the knee under the center of the hip and over the center of the ankle. More recently, though, the concept of kinematic alignment has garnered more attention. Kinematic TKA alignment seeks to restore the “prearthritic” anatomy of a patient’s knee, typically providing for a bit of residual tibial varus and femoral valgus compared to what surgeons used to mechanical-axis alignment might aim for. The rationale for this approach is that it may more-closely replicate the dynamic function of a normal knee, perhaps decreasing the need for soft-tissue releases; some work suggests kinematic TKA alignment may be associated with better scores for pain and function [2, 3]. …
