Abstract
Total knee arthroplasty is a widely used surgery to treat moderate to severe knee
osteoarthritis, usually with favorable outcomes but a controversial patient dissatisfaction
rate. Potential multiple causes of this dissatisfaction have been extensively studied,
with a recent growing debate surrounding the type of alignment for knee arthroplasty,
especially considering the advent and advantages brought by robotic surgery.
Over the years, mechanical alignment has been the gold standard in knee arthroplasty.
However, in the 21st century, new rationales have emerged, many resulting from robotic
surgery. In this study, we categorized alignments into three major groups, discussing
the general characteristics of each one and the current approach used in our institution,
believing robotic surgery is a game changer.
