What Is RoboLens FT3D? Simple Explanation of Robotic Knee Surgery in Chandigarh

When patients hear “robotic knee surgery,” most of them imagine a robot doing the operation on its own with no surgeon in the room.

That is not how it works at all.

Let me explain what RoboLens FT3D actually is — in simple terms.

The Problem With Traditional Knee Replacement

In a normal knee replacement, the surgeon uses special tools and guides to cut the bone and fit the new implant. The measurements are taken from X-rays before the operation and from what the surgeon sees during surgery.

This method has helped millions of patients. It works well. But here is the issue — every knee is slightly different. The shape, the angle, the alignment — all vary from person to person. Even between your left and right knee.

When the surgeon is cutting by hand using guides, there is always a small chance the implant is placed slightly off. Even 2 or 3 degrees of misalignment can cause the implant to wear out faster — or the knee to feel unnatural.

What Does RoboLens FT3D Actually Do?

RoboLens FT3D is a robotic guidance system. The “FT3D” stands for Fluoroscopy-Tracked Three-Dimensional — which basically means it creates a live 3D map of your knee during the operation.

While the surgeon is operating, the system is constantly tracking exactly where the surgical instruments are in relation to your knee bone. It gives the surgeon real-time information — like a very precise GPS for the operation.

Before any bone is cut, the system tells the surgeon exactly where to cut and by how much. The surgeon can see if the plan is right and make adjustments before doing anything.

The result? The implant is placed with much higher accuracy than in traditional surgery.

What Does This Mean for the Patient?

In simple words — a more natural-feeling knee.

Because the implant fits perfectly, the knee moves the way it should. Patients who have had robotic knee surgery often say their knee feels like their own — not like an artificial joint.

Recovery is also faster. Because the surgery is more precise, less bone and tissue is disturbed. There is less swelling, less pain in the first few days, and patients start walking sooner.

And over the long term, the implant lasts longer. A well-placed implant wears evenly and has less chance of loosening early.

Who Can Have This Surgery?

Most patients who need knee replacement can have robotic-assisted surgery. It is especially good for:

• Younger, active patients who want the implant to last as long as possible
• Patients with unusual knee shape or previous injuries
• Patients who have had previous knee operations
• Patients who want a partial knee replacement (only one part of the knee replaced)

Is It Available in Chandigarh?

Until recently, robotic knee surgery with RoboLens FT3D was only available in a few big cities like Delhi and Mumbai.

Now it is available in Chandigarh. Patients from Punjab, Haryana, Himachal Pradesh and surrounding areas no longer need to travel far for this technology.

What Happens at a Consultation?

If you are thinking about this surgery, the first step is a proper check-up. This includes X-rays taken while standing, a clinical examination, and a discussion about your daily life and what you want to be able to do after surgery.

Not every patient needs a full replacement. Some people do better with a partial replacement or resurfacing. A proper consultation will tell you exactly what suits your situation.

Dr. Tarandeep Singh Gill is one of the few surgeons in India trained specifically in RoboLens FT3D robotic knee resurfacing. He is based in Chandigarh and has performed over 6,000 joint replacement surgeries, with fellowship training from Germany.

If you are experiencing knee or hip pain, book a consultation with Dr TS Gill at Max Super Speciality Hospital, Phase 6 (Sector 56), Mohali. Early assessment leads to better outcomes.
