Abstract

"Increased aseptic tibial failures in patients with a BMI ≥35 and well-aligned total knee arthroplasties" published in The Journal of Arthroplasty on July 2, 2015 draws the conclusion that the risk of revision total knee arthroplasties (TKA) due to aseptic tibial component loosening is two times greater in patients with a BMI ≥35 kg/m(2), independent of age or limb alignment. This result confirms that obese patients are at a higher risk of mechanical complications after performing TKA, independently from the risk of infection. This study suggests that the management of obese patients for TKA must be meticulous, careful, and should inspire from great bone deformations in valgus of varus when choosing implants.
