Overview

Robotic joint replacement is a new type of orthopaedic surgery that uses robots to improve the accuracy of joint replacements. It is most often done on the knee and hip. The surgeon controls the robotic platform, unlike fully automated systems. Surgeon plans and performs surgery using detailed 3D imaging and computer guidance. The system helps ensure that everything is properly aligned, that the implant is in the best position, and that healthy bone and soft tissue are not damaged. You can use robotic joint replacement to replace all of your knees or just some of them, as well as your hips. The main goal is to make surgery more accurate, reduce the risk of complications, and, over time, improve joint function.

Why It's Done
When conservative treatments don't work, robotic joint replacement is done on people with severe arthritis or joint degeneration. It is chosen when better surgical accuracy could help with the alignment and balance of the implant. For long-term durability and better movement, it's important to put joint parts in the right places. With the help of robots, surgeons can customise the procedure to fit the patient's unique anatomy, which may lessen pain and speed up recovery.

What to Expect
To make a 3D model of the joint, doctors use detailed imaging, such as CT scans or specialised X-rays, before surgery. The surgeon uses this model to determine ahead of time how big, how straight, and where to place the implant. Anaesthesia is given to the patient during the procedure. As the surgeon prepares the bone and inserts the implant, the robotic system provides real-time feedback and guidance. The robotic arm helps the surgeon make very precise cuts in the bone, but the surgeon is always in charge of the operation. Before closing the incision, the joint's alignment and movement are checked after the implant is placed. After surgery, care is similar to that of a traditional joint replacement, including pain management, blood clot prevention, and getting up and moving around quickly. Physical therapy starts soon after surgery to help you get stronger and move around again.

Recovery & Outlook
Recovery after robotic joint replacement is similar to that after traditional surgery, but some patients may have better early function because the implants are placed more accurately. Most people can start walking with help within a day or two. It may take a few months for the joint to fully heal, depending on which one it is. Robotic-assisted procedures are intended to make implants last longer, improve joint function, and reduce the risk of long-term complications. Patients usually feel much better and have less pain after receiving the right rehabilitation and follow-up care.
