The aim of our study was to compare the radiographic alignment unicompartmental knee arthroplasty (UKA) with using conventional non-navigation technique and computer-assisted navigation technique. Our study was focused on bearing alignment on clinical outcome of knee. In our department we have performed between January 2005 and December 2012 106 UKA. All patients were examined clinically and radiologically before and after operation. There were implanted two types of UKA, 67 of UKA were performed by The PRESERVATION™ (DePuy) with navigation and 39 UKA Oxford® Partial Knee (Biomet.) were performed by conventional technique. In our study we have evaluated 104 of medial UKA divided to groups, 65 implantation of The PRESERVATION™ and 39 implantation of Oxford® Partial Knee UKA. We have evaluated 101 patients, 61 women, 40 men, average age 66,5 (50–82) years. Firstly we performed measurement of parameters determine alignment UKA. These values were written down and the deviation of norm was established. Results were divided in two groups, one with values of normal range and the second beyond normal range. Values of all UKA were matched with clinical outcome postoperatively. This assessment was performed by The Knee Society Clinical Rating System (Knee score).Introduction
