This paper aims to present a possible application of Generalized Nets theory within the field of orthopedic and traumatology rehabilitation. The model delineates a potential algorithmic protocol for the rehabilitation of patients suffering from osteoarthritis, with various transitions in the model symbolizing distinct components of the rehabilitation process. The proposed framework is suitable for integration into decision support systems, tele-rehabilitation platforms, and the optimization of physiotherapy protocols for osteoarthritis, grounded in established best practices and enhanced rehabilitation strategies.
