ABSTRACT
OBJECTIVE:
To compare the effects of Computer-assisted navigation (CAS) and conventional location technique in total knee arthroplasty (TKA).METHODS:
Eight patients (11 knees) underwent CAS and 9 patients (11 knees) underwent conventional location technique for TKA. Follow-up was conducted for 5 - 12 months. The outcomes were compared.RESULTS:
The mechanical axe error of the CAS group was (2.14 +/- 0.25) degrees, significantly less than that of the conventional group [(5.12 +/- 2.13) degrees, P = 0.005]. The soft tissue balance angle variable of the CAS group was (1.04 +/- 0.18) degrees, significantly less than that of the conventional group [(4.12 +/- 1.72) degrees, P = 0.005]. The soft tissue separation variable of the CAS group was (3.4 +/- 1.2) mm, significantly less than that of the conventional group [(6.1 +/- 2.4) mm, P = 0.005]. No fat embolism occurred in these 2 groups. The operating time of the CAS group was (82 +/- 18) min, significantly longer than that of the conventional group [(59 +/- 11) min, P = 0.005].CONCLUSION:
CAS causes more reliable artificial joint implantation and better soft-tissues balance, however, needs more operating time.
