Sažetak
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 0° and 90° femoral flexion contact points, respectively. The OA knees
had longer curve radiuses medially and laterally at 0°, 10°, and 20° 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 in designing of knee endoprostheses, in a manner to
achieve better individual sizing.
