Robotic Knee Replacement Surgery

• Robotic knee replacement is an advanced type of surgery where a robotic system helps the surgeon perform the procedure with high precision. You can compare it to a navigation system guiding the surgeon. In the same way, the robot does not perform the surgery on its own. The surgeon is always in control, and the robotic system only assists by giving real-time guidance.


• This technology allows the surgeon to plan everything before the surgery, including the exact placement of the implant. During the procedure, the robotic system ensures that the cuts are made accurately and safely.

• In traditional knee replacement, doctors use X-rays and manual tools to perform the surgery. While this method is effective, it depends more on the surgeon’s experience and manual accuracy.


• In robotic-assisted surgery, a 3D scan of your knee is taken before the operation. This creates a detailed model, helping the surgeon plan each step in advance. The robotic arm then helps in making precise cuts and placing the implant in the correct position.

• The knee is one of the most important joints in the body. The knee joint links the femur (thigh bone), tibia (shin bone), and patella (kneecap). The ends of these bones are covered with cartilage, which helps in smooth movement.


• Two C-shaped menisci act as cushions and help absorb shock in the knee. Ligaments provide stability, and fluid inside the joint helps it move smoothly.


• Over time, due to aging or injury, the cartilage can wear out. This can cause pain, stiffness, and reduced movement.

• The most common cause of knee damage is osteoarthritis, which happens due to wear and tear of the joint over time. As the cartilage breaks down, the bones start rubbing against each other, causing pain and swelling.


• Other causes include rheumatoid arthritis, which is an autoimmune condition, and injuries such as ligament tears or fractures. Age, obesity, and lifestyle factors can also increase the risk of knee damage.


• In advanced stages, the knee may become stiff, painful, and even deformed, making daily activities very difficult.

• You may need surgery if your knee pain is severe and affects your daily life. If you find it difficult to walk, climb stairs, or sleep due to pain, it is a warning sign.


• Another important indicator is when X-rays show a “bone-on-bone” condition, meaning the cartilage is completely worn out. If medicines, injections, and physiotherapy no longer provide relief, surgery may be the best option.


• Reduced quality of life is also a key factor. If you are unable to enjoy normal activities or depend on others for basic tasks, it is time to consult a specialist.

• Before surgery, the doctor will conduct tests like blood work, ECG, and scans to ensure you are fit for the procedure. A 3D scan of your knee is then used to create a surgical plan.


• On the day of surgery, anesthesia is given, and the surgeon begins the procedure. The robotic system helps guide the surgeon in making accurate cuts and placing the implant correctly.


• Once the implant is fixed, the wound is closed, and you are moved to recovery. Most patients are encouraged to start walking within a day.

• Robotic knee replacement offers several advantages. It provides higher accuracy in implant placement, which improves the function of the knee. Patients usually experience less pain after surgery because there is minimal damage to surrounding tissues.


• Recovery is faster, and many patients are able to walk within a few hours after surgery. The improved alignment of the knee also increases the lifespan of the implant.


• Overall, this method offers better outcomes and helps patients return to their normal life more quickly.

• This surgery is suitable for patients with severe arthritis or long-term knee pain that does not improve with other treatments. It is especially helpful for people with knee deformities like bow legs or knock knees.


• Patients who have tried medicines, injections, and physiotherapy for several months without relief can consider this option. However, a proper medical evaluation is necessary to decide the best treatment.

• Recovery after robotic knee replacement is usually faster compared to traditional methods. Most patients can stand and walk within a day using support.


• Within a few weeks, you can start walking without assistance and perform daily activities comfortably. Full recovery may take a few months, after which you can enjoy activities like walking, cycling, and swimming.


• Maintaining a healthy lifestyle and following your doctor’s advice is important for long-term success.
