Total knee arthroplasty (TKA) is a very effective method in the surgical treatment of advance stage gonarthrosis, that increases the functionality of the knee joints and improves the quality of life of the patients. However, some of the patients who underwent this operation are not satisfied. In recent years, robotic-arm-assisted TKA using computer navigation gained popularity as a way to improve patient satisfaction. This system allows the surgeon to achieve the bone cuts more accurate to preoperative planning and to receive intraoperative feedbacks which contribute to regaining of knee kinematics and soft tissue balance. There is increasing evidence that robotic-arm-assisted TKA with computer navigation leads to prolonged implant survival and improved functional outcomes.
