Abstract

Abstract:

BACKGROUND: It is still controversial whether computer-assisted navigation elevated the accuracy and clinical outcomes of total knee arthroplasty.

OBJECTIVE: To analyze the literatures in English and Chinese on computer-assisted navigation total knee arthroplasty, and to evaluate the clinical outcomes between computer-assisted navigation and conventional total knee arthroplasty.

METHODS: We retrieved PubMed, Ovid, Elsevier, China National Knowledge Infrastructure and Digital Library for literatures concerning randomized controlled trial of clinical outcomes of computer-assisted navigation and total knee arthroplasty published from January 1^st 2005 to December 31^st 2013. Meta analysis was performed with RevMan 5.0 software from the Cochrane collaboration. Clinical outcomes of computer-assisted navigation total knee arthroplasty and conventional technique were compared. The heterogeneity of data was checked.

RESULTS AND CONCLUSION: A total of 16 randomized controlled papers were included in this analysis. Computer-assisted navigation group consisted of 1 322 knees, and the conventional group consisted of 1 299 knees. Compared with the conventional group, patients in the computer-assisted navigation group had a significantly lower risk of implant malalignment at more than 3° as well as more than 2°, malalignment for both coronal femoral component and coronal tibial component of > 3°, and both sagittal femoral component alignment and tibial slope at > 3° malalignment. The meta-analysis did not find a significant difference in the sagittal tibial component alignment, the rates of complications, axial (rotational) alignment of the femoral component and the tibial component between both groups. These data indicated that computer-assisted navigation group had significant improvement in alignment of the limb and the component position, but long-term clinical outcomes using computer-assisted surgery in total knee arthroplasty require further investigation.
