Abstract		Aim of this study was to estimate how knee osteoarthritis (OA) affects the shape of femoral condyles by comparing the radiuses of condylar curves between healthy and OA knees. Seventeen female and five male patients with established diagnosis of knee OA were included in the study. Radiuses of medial and lateral condylar curves were calculated from the side view knee X-ray by original mathematical equation and compared to referent values of healthy knees, after adjusting to body height. The average radiuses of condylar curves were between 52.6 ± 6.2 and 17.6 ± 3.5 mm medially, and between 43.3 ± 8.4 and 15.4 ± 3.7 mm laterally, for 0derees and 90degrees femoral flexion contact points, respectively. The OA knees had longer curve radiuses medially and Laterally at 0derees, 10derees, and 20degrees femoral flexion contact points in comparison to the healthy sample (P<0.001; t-test). Our results suggest that the shape of the femoral condyles in OA knees is changed. It should be aware not only in researching of OA etiology,, but also an designing of knee endoprostheses, in a manner to achieve better individual sizing.
