Navigated Total Knee Replacement

Abstract

Navigated knee replacement provides few advantages over conventional surgery on the basis of radiographic end points. Its clinical benefits are unclear and remain to be defined on a larger scale.

Two year follow-up comparing computer assisted versus freehand TKR on joint stability, muscular function and patients satisfaction

“…Although we did not see statistically significant differences in our series except for the postoperative leg alignment the authors recommend the use of a navigation system because of the described advantages such as better leg alignment and better component orientation [3,27]. Our study has some limitations.…”

Evaluation of the accuracy of patient-specific cutting blocks for total knee arthroplasty: a meta-analysis

“…Studies were included if they were randomized controlled trials (RCT) or quasi-randomized controlled trials, or if they used non-randomized prospective cohorts and historical cohorts [24].…”

Does computer-assisted surgery improve postoperative leg alignment and implant positioning following total knee arthroplasty? A meta-analysis of randomized controlled trials?

“…A previous meta-analysis [6] evaluated the radiographical outcomes after computer-navigated knee arthroplasty was performed and found a reduction in outlier rates for the mechanical leg axis. Another two meta-analyses [13,67] showed that the computer navigation system improved component orientation and mechanical axis of the lower limb in TKA.…”
