Title: Radiological and functional assessment between conventional and navigation knee arthroplasty- Indian experience


This prospective study compared the radiological measurements of knee and functional outcomes in patients who underwent navigation total knee arthroplasty with conventional total knee arthroplasty preoperatively and 3 months post operatively. The radiological measurements included mechanical axis of the knee in the frontal plane, femoral and tibial slope in sagittal pane of the components. The total number of patients included in the study were 420, men 114 and 306 women over a period of 5 years performed by a single knee surgeon.
From the study, the conventional group had 221 patients and navigation group had 199 patients. The mean preoperative mechanical axes was 3.6 varus angle in conventional group and 4.8 degrees varus angle in navigation group.
Post operatively in the frontal plane, valgus/varus deviation of 5 degrees or more were observed in 22 patients in conventional compared to 6 patients in navigation group. In sagittal view the tibial component slope +/- 5 degrees were observed in 24 patients in conventional group and 12 patients in navigation group. The femoral component sagittal slope of +/- 5 degrees were observed in 22 patients in conventional group and 14 patients in navigation group. The overall clinical knee society score including range of motion did not show significant difference between both the groups.
The navigation system has helped in achieving more reliable and reproducible mechanical alignment that may influence the longevity of the implants. However, no difference in clinical outcomes were observed between the groups.
