The invention provides a porous
meniscus substitute modeling and a preparation method thereof. The modeling method comprises the following steps: scanning the
meniscus part of a patient by using CT, performing
image processing on a scanned image to obtain a
meniscus model matched with the patient, performing parameter acquisition on the concentrated
compression stress,
shear stress and
stress distribution of the
femur,
tibia and meniscus part of the patient at the meniscus, and setting the pore shape,
pore diameter and
porosity of the pores in the porous meniscus substitute by adopting a parametric modeling mode to obtain a final meniscus substitute model. The model is subjected to a 3D printing or
injection molding process to obtain the porous meniscus substitute. The porous meniscus substitute prepared by the invention can be matched with the meniscus of the user, is favorable for rapid formation of meniscus tissues after
transplantation, and has the biomechanical properties meetingthe requirements of
knee joint parts; and in addition, through the cooperation of hydrogel and a
porous scaffold, the effects of transmitting load, absorbing oscillation and improving the
joint stability of the meniscus substitute can be greatly improved.
