3D-printed model of the proximal tibia for MAT surgical planning and execution. (A) The 3D-printed model of the proximal tibia is used preoperatively to assist in allograft selection, ensuring a graft that closely matches the recipient’s anatomy. (B) The meniscal allograft is fitted onto the recipient site in the tibia using the 3D model. This process allows surgeons to ensure proper allograft sizing, optimize graft passage, and achieve the most accurate anatomical positioning of the meniscus, thereby reducing the risk of extrusion. (C) The 3D-printed model aids in the accurate reproduction of tunnel positioning and angulation during surgery. This ensures that the cutting and drilling parameters (position and angle) are precisely replicated on the patient’s bone, avoiding tunnel convergence in ACL reconstruction, tibial osteotomy, and MAT cases
