Advanced mobile-bearing surgical technique.

Abstract

Consistent success in total knee arthroplasty (TKA) is dependent on achieving basic surgical goals that include a neutral mechanical axis, a restored joint line, and equally balanced flexion and extension gaps. Although these surgical goals apply to both fixed-bearing and mobile-bearing TKAs, concerns about bearing stability in mobile-bearing implants require surgeons to be aware of flexion gap stability. The increased awareness required to achieve flexion gap stability with the mobile-bearing implant not only provides stability but also encourages surgeons to adhere to basic surgical principles.
