Scott DF - This inquiry was set up to detail the minimum 5-year results of a prospective, randomized Level of Evidence 1 study that assessed cruciate-sacrificing total knee arthroplasty (TKA) using either a posterior-(PS) device or a condylar-stabilized (CS) device. It was presumed that the clinical outcomes of both groups would be equivalent and that there would be differences in operative time and/or blood loss parameters. Findings demonstrated that excellent clinical, functional, and radiographic outcomes were afforded by the CS knee and these outcomes were comparable to the results achieved with the PS knee, with a lower incidence of mechanical sensations. Overall, the use of a CS device as an alternative to the PS device was supported in this study.
