Comparative study between computer assisted-navigation and conventional technique in minimally invasive surgery total knee arthroplasty, prospective control study.
J Med Assoc Thai. 2008 Sep; 91(9):1382-8.JM

Abstract

BACKGROUND

Both Minimally Invasive surgery (MIS) and Computer-Assisted Surgery (CAS) are useful in Total Knee Arthroplasty (TKA). Minimally invasive total knee arthroplasty was associated with decreased blood loss, shorter hospital stays, and increased range of motion. Computer-assisted surgery in total knee arthroplasty was developed to improve the positioning of implants during surgery.

OBJECTIVE

To evaluate radiographic results relative to component position and limb alignment when using a navigation system compared with conventional technique in MIS-TKA.

MATERIAL AND METHOD

A prospective control study was performed in 180 patients who underwent total knee arthroplasty by one surgeon. All patients were randomly divided into two groups, Conventional and Navigation TKA. Intra-, post-operative data, and postoperative limb alignment were recorded for comparison in both groups.

RESULTS

The postoperative mechanical axis was within 3 degrees of neutral mechanical alignment in 94% of the navigation group and 87% in conventional group (p = 0.13). Registration time of navigation group is 13.58 minutes. No statistical significant difference was found in tourniquet time and postoperative blood loss in both groups.

CONCLUSION

The use of navigation in total knee arthroplasty increases accuracy in limb and implants alignment, and does not increase complications and surgical times.
