Abstract
The article provides a comparative analysis of the functional results of total knee arthroplasty and knee postoperative stability in the frontal plane in 124 patients (22 men and 102 women) suffering from gonarthrosis, aged 51 to 83 years (average 69.8 years), operated on with using a standard technique (n = 62) or using a computer navigation system (n = 62), observed for 12 months from the moment of surgery. The use of the navigation system made it possible in a number of cases to achieve more accurate resection of the femur and tibia (deviations from the anatomical axis in 6.5 % of cases versus 19.4 % in the control group), as well as to provide the necessary soft tissue tension to achieve the most accurate balance of the knee joint during the entire range of motion after arthroplasty (stress tests founded frontal plain knee instability of the operated knee in 3.2 % cases in navigation group versus 8.1% cases in control group), however, no data on the reliable superiority of the functional results at the indicated follow-up time were found.
