Short Term Efficacy of Computer Guided Total Knee Arthroplasty and Traditional Total Knee Arthroplasty
Objective:To retrospectively study the short-term efficacy of total knee arthroplasty with computer navigation system(Knee3 software,Brainlab,Germany)and traditional total knee arthroplasty.Methods:A retrospective study was conducted on 124 patients who underwent total knee arthroplasty between December 2020 and May 2022.All were fol-lowed up for 3 months.63 patients underwent traditional total knee arthroplasty and 61 patients underwent total knee arthroplasty under computer-assisted navigation.Preopera-tive data were recorded,including gender,age,body mass index,hemoglobin concentration,hip-knee-ankle angle,range of motion,visual analogue scale(VAS)score.Oxford knee score.Intraoperative data was recorded,including anesthesia mode,operation time and intraoperative blood loss,and postoperative data was recorded,including hemoglobin concentra-tion,surgical complications,VAS score,knee prosthesis angle(α,β,γ,σ),hip-knee-ankle angle,range of motion and Oxford knee score.Results:The operation time was(1.62±0.40)h in the traditional group,(1.97±0.52)h in the navigation group(P＜0.05),the amount of bleeding was(150.32±60.69)mL in the traditional group,(128.85±57.01)mL in the navigation group(P＜0.05),and VAS score(3.63±0.73)points in the traditional group,(2.98±0.98)points in the navigation group(P＜0.05).The hemoglobin in the traditional group was(103.44±11.89)g/L,and(108.82±9.38)g/L in the navigation group before discharge(P＜0.05).There was difference in knee prosthesis angle(α,β,y,σ),hip-knee-ankle angle,range of motion and Oxford knee score at a follow-up of 3 months after surgery(P＜0.05).Conclusion:Total knee arthroplasty with computer navigation system can reduce early postoperative pain,intraoperative bleeding,and post-operative anemia and improve the accuracy of prosthesis placement angle and lower limb force line.There is no advantage in short-term improvement of joint range of motion and knee joint function.
