Background: Restoration of neutral alignment of the leg is an important factor affecting the long-term results of total knee arthroplasty. Despite the use of modern instruments in total knee arthroplasty, component malalignment remains a problem. Computer-assisted systems have been developed in order to improve alignment of components. Th e objective of this study was to determine whether the computer-assisted total knee arthroplasty is superior to the conventional surgical method with regard to the precision of implant positioning. Patients and methods: A total of 44 patients were included in the study. Twenty-three patients underwent surgery using a computer- assisted navigation system. Th e control group included 21 patients, who were operated on using the conventional technique. Th e groups were similar with regard to age, gender, diagnosis, body mass index, side of the operated limb, implants and preoperative value of IKSKS. Th e two methods were compared for alignment of the leg and the orientation of components on post-operative long-leg coronal and lateral fi lms. Results: Th e groups were not signifi cantly diff erent with regard to the accuracy of component positioning as compared to that achived by conventional total knee arthroplasty (p > 0,05). Postoperative range of motion of the knees and postoperative value of IKSKS were similar in both groups. Th e operating time was longer in the computer-assisted total knee arthroplasty, by 30 minutes on average. Th e blood loss was greater in the computer-assisted total knee arthroplasty, by approximately 70 mL on average. Conclusions: Computer-assisted total knee arthroplasty yields better correction of leg alignment and orientation of the components compared with the conventional technique. However, these results were not statisticaly signifi cant. Potential benefi ts in the long-term outcome and functional improvement require further investigation. |
