Abstract
The main purpose of the article is to describe the methodology used for multi-criteria optimization of the geometric features of the orthopedic implant used for the reconstruction of the anterior cruciate ligament located in the knee joint. The methodology includes: 1. Method of development of the bones of the knee joint model; 2. Method of multi-criteria optimization of the geometric features of the orthopedic implant using an artificial immune system, the objective function and the Pareto front; 3. Expert evaluation method based on forms. The work confirmed that the assumed thesis, a multi-criteria optimization using an artificial immune system, which is a specially defined objective function, and the Pareto method, which allows to determine the geometrical features of the implant, will lead to fulfill optimal blood perfusion and sufficient strength properties of the implant simultaneously. We conclude that the described methodology allowed to achieve the optimal geometrical features of the orthopedic implant used for reconstruction of the anterior cruciate ligament located in the knee joint.

Summary
An interdisciplinary approach is very important when solving engineering and medical issues, resulting in significant advances in medical technologies.The growing civilization is causing an increase of the number of injuries among citizens. An increasingly frequent injury is the rupture of the Anterior Cruciate Ligament (ACL), which is located in the knee joint. The subject of this article is the optimal selection of the design features of the new implant used during the reconstruction of the anterior cruciate ligament. Such a reconstruction consists of inserting a graft (usually autogenous, e.g., a tendon) in place of the broken anterior cruciate ligament in the knee joint. The main problem during the surgery is the proper placement of the new graft in the bones of the knee joint and ensuring adequate fluid flow of blood and other body fluids in order to “nourish” it
