TKA Navigation Using the Medacta System
Since its inception over a decade ago, the goal of more accurate prosthesis placement has routinely been met (Bäthis et al. 2004a, 2004b; Bohling et al. 2005; Chauhan et al. 2004a, 2004b; Chin et al. 2005; Krackow et al. 2003; Oberst et al. 2003; Saragaglia et al. 2001; Sparmann et al. 2003; Stulberg et al. 2000, 2002). Although the original prediction of higher longevity with more accurate placement and even distribution of forces has not yet been proven, a meta-analysis of 29 studies of computer-assisted surgery (CAS) vs. standard mechanically instrumented total knee arthroplasty (TKA) showed that errors of 3° occurred in 9% of the former procedures vs. 31.8% of the latter.
