At present, the conservative treatment for knee arthritis is mostly using anti-inflammatory and analgesic drugs, but the effect is mostly temporary, and can not prevent its progress and surgery is usually the last treatment method. Total knee arthroplasty, also known as TKA, is one of the most effective treatments for osteoarthritis of the knee that has progressed to the end stage. The inevitable human factor in conventional total knee arthroplasty (TKA) frequently results in poor positioning of the prosthesis during the reconstruction of the lower limb's biomechanical axis. This can lead to severe postoperative pain, accelerated wear of the prosthesis, early loosening, and other problems in the affected knee, which has always been a primary concern for orthopaedic surgeons. Over the course of the past few years, China has gradually begun to develop joint robots. The idea is to plan the surgical plan based on the anatomical structure of the affected limb before the operation, and then to use a mechanical arm and a visual system to assist in the implantation of the prosthesis while the operation is being performed. The treatment costs of robot-assisted technology, on the other hand, vary greatly, and there is still a relatively small amount of high-quality evidence on clinical efficacy. This is because the field of robotic-assisted technology is a relatively new one that has gradually developed over the past few years.
