【 摘 要 】

Kinematic alignment total knee arthroplasty(KA-TKA) was advocated by Howell et al,1and with growing interest there have beenincreasing reports on various approaches toit. Such enthusiasm, however, has also ledto confusion. In order to better understandKA-TKA and its derivatives, clarification maybe provided by consideration of three keyknee elements: morphology, soft-tissue, andalignment. Each element determines and isdetermined by the others, maintaining thebest harmony of the elements to constructthe best unique kinematics on an individualbasis. Differing from the original concept ofkinematic alignment, which is alignment thatfollows the three kinematic axes (cylindrical,patellar, and tibial rotation),2 recent KA-TKAinstead aims to recreate the patient’s originalkinematics by setting the harmony of thesecomponents in a bespoke alignment.
