The position of the centre of the femoral head relative to the midline of the pelvis: A consistent landmark in total knee replacement surgery
The Knee, 06/01/2012
Alazzawi S et al. – The results demonstrate that the position of the centre of the femoral head has very little variability, irrespective of patient age or body–mass index. If the gender–specific mean femoral head to midline distance is used to estimate the location of the femoral head centre, a line from this point to the centre of the femoral condyles will deviate from the true mechanical axis by no more than 1.5°, in 98% of cases.
