Development of a novel geometrically-parametric patient-specific finite element model for anterior cruciate ligament reconstruction.

Purpose: A personalized model of the knee joint, with adjustable effective geometric parameters for the transplanted autograft diameter in Anterior Cruciate Ligament Reconstruction (ACLR) using the bone-patella-tendon-bone (BPTB) technique, has been developed. The model will assist researchers in understanding how different graft sizes impact a patient's recovery over time.

Methods: The study involved selecting a group of individuals without knee injuries and one patient who had undergone knee surgery.
