Rotating platform knees: an emerging clinical standard: in the affirmative.

Total knee arthroplasty (TKA) is one of the most frequently performed reconstructive operations in the world today. It has been extended to younger and more active patients. Wear at the articulation and fixation loosening are the principle modes of TKA failures. Data from clinical follow-up, laboratory testing, and in vivo kinematic motion analysis have all demonstrated excellent biomechanics, wear characteristics, and fixation durability with mobile-bearing TKA designs. This review summarizes some of the most recently published data in the efficacy of rotating platform TKAs.
