Stress, displacement and contact area analysis in different models. IK intact knee, PT partial tear, ERT entire radial tear, EOT entire oblique tear, MR meniscus repair, PM partial menisectomy. a, b There was no significant difference in the contact stress between the medial and lateral tibiofemoral articular cartilage surfaces in different models. c The medial meniscus posterior root stress in the PT and MR models was higher than that in the IK and PM models. d The displacement of the medial meniscus in the ERT and EOT models was greater than that in the IK, PT, MR, and PM models. e, f The femoral and tibial cartilage contact areas of the ERT and EOT models were smaller than those of the other four models. *P<0.05
