Analysis of Implant Alignment and Early Functional Results of Total Knee Replacement Performed Using Computer Navigation System


Knee implant alignment analysis and comparative assessment of functional results of 47 total joint replacements with computer navigation system (main group) versus 50 conventional arthroplasties (control group) were performed. Computer assisted system improved the accuracy of limb alignment after knee arthroplasty and reduced the rate of deviations. The position of femoral component in frontal plane and tibial component in sagittal plane showed statistically reliable differences between two groups (p<0.05). Within the first 6 months after surgery knee joint function (KSS and WOMAC score systems) in the main group was trustworthily better as compared to the control group. Later on those differences smoothed over.
