It is difficult to imagine the modern world and medicine without the application of computer technologies, which significantly enhance doctors’ work and improve its quality. These technologies positively impact the speed and accuracy of surgical interventions. Specifically, in knee arthroplasties, precise measurements and calculations are crucial for correctly implanting endoprostheses and avoiding postoperative complications to achieve favourable biomechanical outcomes.

The aim of the study was to compare experience of applying a modern computerised navigation system in identifying the actual resection levels of the femur and tibia during knee arthroplasty, with conventional methods experience.

Materials and methods. The Orthopilot navigation system, produced by the Aesculap company, was used at the Department of Traumatology, Orthopaedics, and Combat Trauma of Odesa National Medical University, based at the University Clinic. This system allows the real-time determination of the most optimal resection points for the femoral and tibial bones during 3D modelling of the surgical procedure. Surgery using a computed navigation system was performed on a 55-year-old female patient with grade III gonarthrosis underwent treatment and were examined postoperatively for six months. The study was conducted in accordance with the provisions of the Declaration of Helsinki, patient was informed about the objectives of the study and provided informed consent to participate in the study and the processing of her personal data.

Results. During the study, it was found that the installation of knee joint endoprosthesіs using a computerized navigation system allows more accurate implant placement and helps to avoid imbalance of the knee joint ligaments and, despite the longer duration of the operation, is considered safe regarding blood loss and postoperative complications.

Keywords: knee joint endoprosthesis, navigation system, surgery, modern technology.
