Fig. 2.
Changes of the hip load in relation to the postoperative position of the COR in the horizontal plane (medial to lateral direction). Every line represents different proximal positions of the COR. For example, the “20-mm line” represents hip load increase when the postoperative COR is moved exactly horizontally from 40 mm medial to 100 mm lateral but at the level which is 20 mm proximal to the ideal COR
