Alineamiento en prótesis total de rodilla: cuestionando los paradigmas

Abstract

Total knee arthroplasty (TKA) is a highly successful procedure; however, we can find dissatisfied patients. Although post-TKA dissatisfaction is a multifactorial problem, there is growing interest in alignment as a modifiable cause of the problem. The ideal alignment in TKA is still controversial and many techniques are described. The classic and most used technique is mechanical alignment, but there are others such as anatomical, adjusted mechanical, kinematic, reverse kinematic alignment and the recently described functional alignment.

This narrative review details the most used alignment techniques, their benefits and problems, and comments on what could be the new guidelines that could guide alignment techniques in the coming years.
