The influence and biomechanical role of cartilage split line pattern on tibiofemoral cartilage stress distribution during the stance phase of gait

摘要: This study presents an evaluation of the role that cartilage fibre ‘split line’ orientation plays in informing femoral stress patterns. A two-stage model is presented consisting a whole knee joint coupled to tissue-level for computational efficiency. The may be easily customised any MRI or CT geometry using free-form deformation. Three patterns (medial–lateral, anterior–posterior and random) were implemented finite element with constitutive properties referring this as field. medial–lateral was similar anatomy derived from imaging studies. Model predictions showed lines’ are formed along line maximum principal strains have biomechanical protecting by limiting deformation area higher thickness.
