In KA, the articular surface is replicated using components aligning with the three kinematic axes. KA-TKA has been gaining popularity, and in addition to the true or calipered KA, various derivatives, such as restricted KA, soft-tissue respecting KA, and functional alignments, have been introduced. Moreover, the functional approach encompasses several sub-approaches. This somewhat complicated scenario has led to some confusion. Therefore, the terminology needs to be re-organized. The term \"personalized alignment (PA)\" has been used in contrast to the MA approach, including all approaches other than MA. The term \"PA-TKA\" should be used comprehensively instead of KA and it represents the recent trends in distinct and unique consideration of each individual case.
