Robotic MIS Knee Replacement

What is Robotic Knee Replacement?

A robotic knee replacement is similar to a traditional knee replacement — the surgeon removes damaged tissue in your knee and replaces it with an artificial joint. The difference is that it is done with assistance from a robotic arm, which allows for far greater precision. In more complex cases, a robotic-assisted knee replacement achieves a better balance in the soft tissues around the knee and more accurately aligns the joint. If you are having a robotic-assisted knee replacement, you do not have to prepare any differently than you would for conventional surgery.

We are delighted to be India’s first to introduce fully active robot for minimally invasive knee replacement surgery

"We are connecting MIS technique with robotics technology. It is user-friendly and flexible and offers precision and safety. For patients, this advanced technology provides exceptional outcomes, minimal infection risk, quicker recovery time and less pain. Patients are able to walk within hours after surgery. It is a life-long solution for patients with joint problems" - Dr. Ashwani Maichand

How is a Robotic Joint Replacement Surgery performed?

The Procedure:

• The robotic arm is prepared and draped with sterile covers to maintain a strictly sterile field and prevent infection.
• The patient is connected to the robot and stabilised for surgery.
• The virtual 3D prototype guides the surgeon throughout the operation; the surgeon confirms the surgical site using the 3D model.
• AI inputs help select a customised implant suited for the patient.
• The robotic arm assists the surgeon in making precise bone cuts on the femur and tibia.
• Implants of varying sizes are trialled to achieve optimal ligament balance — a key step that ensures the new joint feels stable and natural through full range of motion.
• Once the final components are placed and aligned, alignment and range of motion are verified before closing the incision.

Benefits of Robotic Joint Replacement Surgery

• No sutures, minimal pain, and scar-free natural appearance.
• Real-time monitoring to adapt intraoperative changes safely.
• Sub-millimeter accuracy ensures longevity and durability of implants.
• Prevents bone, ligament, and blood loss to a great extent.
• 3D CT scan-based surgical prototype allows precise cuts.
• Highly experienced orthopaedic surgical team.
• Minimal risk of infection and complications.
• Optimal implant positioning with utmost precision.

Symptoms and Signs That May Indicate Knee Replacement

Patients usually reach the point of considering robotic knee replacement when they experience:

• Severe, persistent knee pain
• Difficulty walking, standing, or climbing stairs
• Visible deformities such as varus (bow-leg) or valgus (knock-knee) alignment
• Reduced quality of life and limited participation in social activities
• Conservative treatments no longer providing relief

Causes and Risk Factors

Osteoarthritis is the most common cause of knee problems that lead to knee replacement. It is typically seen in individuals over the age of 60, where progressive wear and tear of the knee joint produces pain and deformity. Other contributing conditions include rheumatoid arthritis, post-traumatic arthritis after old injuries, and severe ligament damage that has destabilised the joint over time. Where the underlying problem is primarily meniscal damage in earlier stages, a joint-preserving Meniscus Replacement Procedure (MRP) may be considered before going to full replacement.

Who is a Candidate for Robotic Knee Replacement?

The requirements for a robotic knee replacement are the same as for a traditional one. The doctor will first try less invasive measures — anti-inflammatory medication, cortisone injections, physical therapy, weight loss, and knee braces. Knee replacement becomes a suitable option when these methods no longer provide relief. Because robotic surgery works without jigs, it can be especially valuable for elderly patients, lowering the risk of complications while placing the implant precisely. For knees where only one compartment is damaged, a partial knee replacement may be an option; for total replacements where the surgeon prefers to spare the quadriceps mechanism, the subvastus approach is also available.

Myths & Facts About Robotic Knee Replacement

Myth: Computer errors are a common problem in robotic joint replacement surgeries.
Fact: It is called robotic-assisted knee replacement because the surgeon works alongside the robot and always holds the robotic arm. The surgeon avoids unintentionally harming nerves, vessels, or important soft-tissue structures by using the haptic boundary — a virtual boundary the robot enforces.

Myth: A robotic knee replacement may not be an option for me.
Fact: Patients who meet the requirements for traditional knee replacement surgery can also undergo robotic knee replacement. The lack of jigs during the procedure significantly lowers the risk of medical complications in elderly patients.

Recovery & Preparing Your Home

Robotic total knee replacement typically has a shorter recovery period than conventional surgery — smaller incisions mean less damage to surrounding bone and tissue. Strengthening your body before surgery helps too: low-impact activity like stationary cycling, swimming, or yoga improves muscle strength and range of motion, while losing even a pound of weight relieves around four pounds of pressure on the knees.

Before you come home, it helps to have a few assistive items ready:

• Walking aids such as crutches, a cane, or a walker
• Shoehorns and sock aids; reachers and tongs
• Grab bars, a raised toilet seat, and a tub chair
• Ice packs or wraps for swelling, and extra pillows to elevate the leg
• Comfortable, loose-fitting clothing that won't rub against the incision site
