Is robotic surgery better for knee replacement?
Robot Surgery is a surgical procedures that are performed using robotic systems. Robotic surgery was developed to try to overcome the limitations of pre-existing surgical procedures and to enhance the capabilities of surgeons performing open surgery with more precision.
Whilst the majority of knee replacement patients claim to have ‘excellent’ or ‘very good’ results from their surgery, nearly 20% of patients are not entirely satisfied. Surgeons who use the robotic system find that it can increase precision, flexibility and control during the operation, thereby leading to increased patient satisfaction.
During all knee replacement surgeries, the damaged bone and cartilage is removed from the joint and and replaced with an artificial joint. Conventional knee surgery relies on the surgeon's skill and experience to make accurate cuts and place the implant correctly, whilst balancing soft tissues i.e. ligaments.
By contrast, robotic-assisted knee replacement surgery uses advanced technology to create a computerized 3D model of the patient's knee joint, which can allow for more precise surgical planning and execution - and less variability. A robotic-arm is then programmed to guide the surgeon’s cuts, based on the CT scans.
‘The current state of robotics in total knee arthroplasty’ found that patients who underwent robotic-assisted knee replacement surgery had better postoperative range of motion, fewer complications, and shorter hospital stays than those who underwent traditional knee surgery.
If you have been told for a Knee Replacement surgery, the questions you need to ask yourself are:
- Have all of the appropriate non-surgical treatments been tried.
- Is my painful knee significantly restricting my day to day activities
If your answers is yes, you may go for a Knee replacement surgery.
