Computer-assisted surgery and rotational alignment of total knee arthroplasty

Abstract

Producing correct rotational alignment is important in total knee replacement. When bony landmarks are used, the transepicondylar axis (TEA) is the reference axis of choice for the femur. Referencing using soft-tissue balance or kinematics is today still speculative. The tibial component rotatory alignment should follow the achieved position of the femoral component. Good rotational alignment of both the tibial and femoral component is difficult to achieve with or without computer assistance. © 2005 Springer Medizin Verlag Heidelberg.
