Osteoarthritis is the most common joint disease in people over 50 years of age. It is a degenerative disease that affects the cartilage of the joints. In the final stages, osteoarthritis causes severe pain in the joints (knees, hips, etc.), creating not only mobility problems in patients, but also psychological ones.

In our country, we are facing severe arthritis conditions due to the delay in treating the disease, resulting in serious disruption of the mechanical axis of the lower extremities and their deformation (great bulging or valgus).

Joint replacement – total joint replacement – is a surgical procedure that provides a definitive solution to this common problem.

The contribution of the development of electronic and robotic technology and their application in Orthopaedic Surgery opened new horizons for the success of knee and hip arthroplasty. The in-depth knowledge of the biomechanics of joints, the different approach to the joint not as an isolated anatomical point, but as a point that belongs to a kinetic whole (electronic study of the kinematics of the entire lower limb), the improvement of materials with the participation of new metals (titanium, tantalum) and finally, the more anatomical design of implants, have been the pillars of the rapid evolution of knee and hip arthroplasty.

On the other hand, the new generation of Orthopaedic Surgeons incorporated computer science knowledge and, combining it with surgical experience and know-how, created a new order of things for the success of this operation.

The robotic technology ROSA was put at the service of Orthopedic Surgery to improve the following:

• The correct placement of implants.
• The accuracy in correcting the mechanical axis of the lower limb.
• The balancing of the soft tissues around the joint, which results in a more anatomical and natural feeling of it, immediately after surgery.
• The safety for the patient, due to the cooperation of the orthopedic surgeon with the robotic system, which provides a continuous flow of information during the surgical procedure, minimizing the possibility of intraoperative and postoperative complications.
• The rapid mobilization of the patient, on the same day of surgery.
• The short duration of stay in the clinic.
• The faster return to daily activities activities (Fast Track method)
• The possible longer lifespan of the implants in the patient’s body (prospect for 25-30 years and more)

The new era of robotic technology for the treatment of severe arthritis is the present and future of Orthopaedic Surgery and is successfully applied at the Interbalkan Medical Center, only by certified Orthopaedic Surgeons.
