Fifteen Allegretto knees were implanted without computer navigation and 15 EIUS knees were implanted with navigation. We compared the survivorship radiological and clinical outcomes of the two groups at an average of years and years respectively. The patients were assessed clinically using the Oxford Knee Score OKS and radiologically using long-leg weightbearing films and non-weightbearing computed tomography alignment measurements. The overall survivorship was at 9 years. A higher proportion of navigated knees were well aligned with a more reproducible position and malaligned knees tended to have a less favourable OKS. However we found no statistically significant difference in survivorship clinical outcome and radiological alignment between the two groups. Introduction Unicompartmental knee arthroplasty UKA has proved to be a popular option in the treatment of isolated medial compartmental osteoarthritis OA with good long term results 1-3 . Isolated medial compartmental OA has been reported to be present in around 21 in males and 12 in females 4 or in 85 of knees with clinical OA 5 . There is little debate that when compared with total knee arthroplasty TKA UKA is less invasive causes less morbidity better reproduces kinematics and therefore offers quicker recovery better range of movement 6 and more physiologic function 7 . However the use of unicompartmental knee replacement has been decreasing in recent years 8 9 and this may be due to the .
