title: Computer-assisted TKA: greater precision, doubtful clinical efficacy: affirms.
abstract: Component and limb alignment are essential surgical variables that influence the long-term performance of a total knee arthroplasty (TKA). Total knee arthroplasty failure remains multifactorial, and computer-assisted surgical techniques may address only part of the failure pathophysiology. Despite attempting to use computer-assisted surgical techniques to improve TKA alignment, recent evidence has reported that the entire nature of the computer-assisted experience is not particularly forgiving, as significant increases in time and complications remain problematic. It appears computer-assisted surgical techniques are not yet "ready for primetime" with reproducible and proven long-term benefits for patients. Further studies are needed to better determine the precise target toward which to aim computer-assisted surgery efforts.
