Abstract provided by Publisher
Background. The aim of this study was to compare the results of TKA performed with the use of a navigation system vs. conventional knee arthroplasty and to evaluate the effectiveness of navigation system support in TKA.
Material and methods. We evaluated patients undergoing TKA for osteoarthritis in the years 2011-2013. Columbus prostheses were implanted in 84 knees. Group 1 included patients in whom TKA was performed with the use of the OrthoPilot Navigation System, and Group 2 was a control group of patientsundergoing conventional TKA. Group 1 ultimately comprised 30 patientsat a mean age of 71.8 years, while Group 2 consisted of 30 patients at a mean age of 73.5 years. Radiographic parameters were evaluated according to the mechanical axis of the leg. Clinical evaluation relied on the VAS and KSSscores.
Results. Mean operation time was 94 minutes in Group 1.It was shorter in Group 2, with a mean of 75 minutes. Postoperative VAS scores did not differ betweenthe groups. Significant improvement was noted between pre- and postoperative in KSS scores in both groups. The control group showed more valgus mechanical axis deviation than varus deviation.
Conclusions. In experienced hands, navigated surgery time may be similar to that of conventional TKA and give superior results, both clinical and radiographic.
