[Comment] Robotics in total knee replacement

AI Summary

Robotics in total knee replacement surgery offers different alignment strategies tailored to patient anatomy, complicating outcomes assessment. Surgeon preference significantly influences the choice between robotic-assisted and conventional techniques.

Can improved outcomes in total knee replacement (TKR) be attributed solely to the choice between robotic-assisted and conventional surgical techniques? When one considers the possible TKR alignment strategies (mechanical, functional, kinematic, and anatomical)1 and the natural heterogeneity of patient expectations, the equation becomes much more complicated. The alignment strategy is chosen by surgeon preference and, in the case of functional, kinematic, or anatomical alignment, is tailored to the patient's specific anatomy.
