Morphometrical studies on the symmetry of the human knee joint: femoral condyles.
The curvature of the tibial part of the femoral condyles in the sagittal plane can be described by mathematical spirals: involutes of a circle. Archimedean and logarithmic spirals. In the order of the accuracy of measurement (+/- 0.2 mm) the curvature can be described by all three spirals.
