Subject characteristics (meanā±āsd) and inclusion criteria for selecting subjects from OAI database to three different KL groups. In KL0 group subjectsā BMI were less than 25 and in KL2 and KL3 groups more than 30. Except BMI of one KL3 subject was more than 28 since there were only 6 subjects whose BMI was more than 30 and who fulfilled all other inclusion criteria. Inclusion criteria are for knee joints used in FE modelling (3 left and 18 right), but in addition initial KL for non-modelled knee joint had to be 0 or 1.
