AIM: This prospective study investigates open-wedge high tibial osteotomy performed with the aid of a kinematic computer-guided navigation system. After the X-ray control the osteotomy was stabilized by internal LCP fixation. The aim of the study was to demonstrate the accuracy of the navigation system and to prove the reliability of the LCP fixation. METHOD: A total of 39 patients were operated between 2002 and 2003 following this method. The outcomes were evaluated at least 2 years after the surgery clinically and radiologically; 21 females (1 female underwent bilateral osteotomy) and 18 males were included in the study sample. RESULTS: Prior to the osteotomy, the mean anatomic lateral tibiofemoral angle (aLTFA) was 181.1 degrees . The desired 4 degrees "overcorrection" of valgus (aLTFA 170 degrees) was found on X-rays postoperatively in all cases. The mean correction was 11.1 degrees. The correction achieved was stable during the 2-year follow-up period. The osteotomy healed in all cases after 4 months. The full range of motion remained after the surgery in all cases. All patients were satisfied with their results. The Lysholm score was 55 points before and 82 points after the osteotomy (27 points difference). CONCLUSION: The computer-assisted open-wedge high tibial osteotomy with tricortical grafts stabilized by LCP fixation gives exact and reproducible results without loss of correction.
