RoboLens FT3D Knee Resurfacing in Chandigarh — Real-Time Robotic Precision

The most advanced robotic knee system in North India. Dr TS Gill is the only surgeon in the region performing RoboLens FT3D — creating a live 3D map of your knee during surgery for unmatched precision.

What Is RoboLens FT3D?

RoboLens FT3D (Functional Tissue Three-Dimensional) is a robotic-assisted surgical platform designed specifically for knee resurfacing and replacement. The defining feature of the FT3D system is that it constructs its three-dimensional map of the patient’s knee during the surgical procedure — not from a scan taken weeks before.

The name tells you exactly what it does. FT stands for Functional Tissue — the system captures how tissue actually behaves under surgical conditions, not how it appeared in a pre-operative scan. 3D refers to the complete three-dimensional model of the knee joint geometry that the system generates in real time on the operating table.

When a patient is anaesthetised and positioned on the operating table, soft tissue tensions, joint angles, and bone anatomy shift slightly from how they appeared on a pre-operative scan. Competing systems — including MAKO (Stryker) and Navio — rely on pre-operative CT data that does not capture these intraoperative changes. RoboLens FT3D captures the knee exactly as it is at the moment of surgery, giving the surgeon the most accurate possible map from which to plan and execute each cut.

Dr TS Gill was involved in the clinical development of the FT3D technique, working directly with the RoboLens engineering team during the system’s design and validation phase. He is currently the only surgeon in North India — spanning Punjab, Haryana, Himachal Pradesh, J&K, and Delhi — who is using the FT3D generation of the RoboLens platform.

The Inventor’s Advantage — Why Dr TS Gill’s Depth of Knowledge Matters

There is a meaningful clinical difference between a surgeon who learned a procedure from a training course and a surgeon who was involved in developing it.

FT3D requires the surgeon to interpret intraoperative data in real time — the system builds a live map of the knee from probe readings and soft tissue tension measurements, and the surgeon uses that map to make positioning decisions on the spot. For straightforward cases with typical anatomy, the process is reliable. But knees are not always typical:

• Some patients have significant varus or valgus deformity that shifts load distribution patterns
• Some have had previous knee surgery that altered the anatomy
• Some younger patients present with unusual, asymmetric wear patterns
• Some have bicompartmental arthritis requiring careful planning of two resurfacing components

In atypical cases, the surgeon’s depth of understanding — not just the system’s operation, but its design logic and the reasoning behind how it generates its model — directly affects how well they interpret the data and make the right call. Dr TS Gill’s involvement in developing FT3D means that when the procedure meets an unusual case, he is reading the system’s output with a level of understanding that trained users cannot replicate.

This is why patients with complex anatomy, previous surgical history, or unusual arthritis patterns specifically seek out Dr TS Gill for their FT3D procedure.

How FT3D Maps the Knee — Step by Step

Understanding how the intraoperative mapping works helps explain why FT3D produces better precision than CT-based systems. The process has seven stages:

Step 1: Positioning

The patient is positioned on the operating table as normal. The knee is exposed through a standard surgical approach. Nothing at this stage is different from conventional knee surgery.

Step 2: Bone Tracking Sensors

Small positional tracking pins are placed in the femur (thigh bone) and tibia (shin bone). These are temporary and removed before closure. They allow the FT3D system to track the exact position and orientation of each bone in real time throughout the procedure — any movement is captured and accounted for automatically.

Step 3: Intraoperative Surface Registration

The surgeon uses a calibrated probe to touch specific anatomical landmarks on the bone surfaces — the femoral condyles, the tibial plateau, and surrounding structures. This process takes approximately 5 to 8 minutes. As the probe touches each landmark, the system records the precise three-dimensional coordinates of that point relative to the tracking sensors.

Step 4: 3D Model Generation

From the surface registration readings and real-time tracking data, the FT3D software builds a complete three-dimensional model of the patient’s knee — created at that moment, on the operating table, under actual surgical conditions. This model includes bone geometry, joint mechanics, and soft tissue tension data. The model does not come from any pre-operative scan — it exists only because of what the system just measured.

Step 5: Surgical Planning on Screen

The surgeon uses the intraoperative 3D model to plan the resurfacing on screen in real time. The position, size, and orientation of the implant are determined based on the patient’s actual anatomy as mapped by the system. Adjustments can be made directly — the plan is not locked in from a pre-operative session weeks earlier. If something in the knee’s anatomy warrants a different approach from what was initially expected, it can be adapted on the spot.

Step 6: Robotic Bone Preparation

The robotic system guides the bone cutting and preparation steps to sub-millimetre accuracy, following the surgical plan established from the intraoperative model. The damaged portion of the compartment is precisely removed, the implant is prepared for seating, and load distribution across the resurfaced compartment is verified on screen before the implant is placed.

Step 7: Implant Placement and Closure

The implant is placed. The knee is tested through range of motion. The wound is closed. Recovery begins. The entire procedure — including the mapping steps — typically takes 60 to 90 minutes.

RoboLens FT3D vs MAKO — Key Differences

This is the most common comparison patients make when researching robotic knee surgery. Both systems use robotic assistance. Both claim precision. But they are built on fundamentally different principles — and understanding that difference matters.

What Conditions Does FT3D Treat?

The knee joint has three distinct compartments. FT3D resurfacing can treat arthritis in any one or two of them:

Medial Compartment Osteoarthritis — the inner side of the knee

This is the most common pattern of knee arthritis. The medial compartment bears more load than the lateral side, particularly in patients with a varus (bow-legged) alignment. FT3D resurfacing of the medial compartment preserves the healthy lateral and patellofemoral compartments completely.

Lateral Compartment Osteoarthritis — the outer side of the knee

Less common than medial arthritis, lateral compartment arthritis is often associated with valgus (knock-kneed) alignment. FT3D precision is particularly valuable here as the lateral compartment has a more complex geometry and slight implant malalignment has a proportionally larger effect on load distribution.

Patellofemoral Arthritis — the kneecap and thigh bone

Arthritis between the patella (kneecap) and femur causes pain at the front of the knee, especially with stairs, squatting, or rising from a chair. FT3D resurfacing addresses this compartment while leaving the tibial compartments untouched.

Bicompartmental Arthritis — two compartments affected

When two compartments are arthritic but the third remains healthy, FT3D allows both to be resurfaced in a single procedure — addressing the full extent of the disease while still preserving the healthy compartment. This is a technically demanding procedure where FT3D’s real-time mapping provides a distinct advantage over conventional instruments.

FT3D is generally not the appropriate choice when arthritis has destroyed all three compartments simultaneously. In those cases, total knee replacement is the indicated treatment.

Who Is Suitable for RoboLens FT3D?

RoboLens FT3D is used for both partial knee resurfacing and total knee replacement. The ideal candidate for partial resurfacing using this system is:

• Knee arthritis confirmed on X-ray, limited to one or two compartments
• Significant knee pain that has not responded adequately to conservative treatment (physiotherapy, injections, anti-inflammatories)
• Intact anterior cruciate ligament (ACL) — necessary for compartmental stability
• Reasonable overall bone quality
• A preference for preserving as much natural tissue as possible

Younger patients (40s, 50s, early 60s) who want to avoid total knee replacement are particularly well-suited. FT3D resurfacing allows them to address the current arthritis effectively while keeping their options open for future treatment if needed. The bone stock that FT3D preserves makes any future conversion to total replacement straightforward.

For patients with severe arthritis involving all three compartments of the knee, RoboLens FT3D is used to guide total knee replacement — delivering the same real-time accuracy advantage for the full procedure.

FT3D and the Younger Patient — Why This Changes Everything

Total knee replacement implants have a finite lifespan — typically 15 to 20 years under good conditions. For a 45-year-old patient, this means almost certain revision surgery by their mid-60s. Revision TKR is significantly more complex than the primary operation, with higher complication rates, longer recovery, and fewer future surgical options.

This creates a serious clinical problem for patients in their 40s and 50s with arthritis that is currently limited to one or two compartments. The historically cautious approach — to “wait until it’s bad enough for a full replacement” — preserves options on paper but allows years of pain and functional limitation to accumulate while the remaining healthy compartments deteriorate under compensatory load.

FT3D resurfacing changes this calculation. By addressing only the damaged compartment with precision that ensures long-term implant durability, it provides:

• Effective pain relief and function restoration now — not after years of deterioration
• Preservation of healthy bone stock — the untouched compartments remain intact
• A natural-feeling knee — ligaments preserved, kinematics close to original anatomy
• A clear future pathway — if arthritis progresses to other compartments years later, conversion to total replacement is straightforward

With FT3D precision, the concern about long-term durability of partial resurfacing — which was legitimate when the procedure was done with conventional instruments — is largely eliminated. Proper implant alignment and balance, confirmed intraoperatively and verified on screen before placement, is what drives implant longevity.

Benefits of RoboLens FT3D

• No CT scan required — eliminates additional radiation exposure and reduces cost
• Real-time accuracy — 3D map reflects the knee as it is during surgery, not weeks earlier
• Sub-millimetre implant positioning — verified on screen before placement, not estimated
• Soft tissue balance optimised — real intraoperative tension readings, not pre-operative approximations
• Faster recovery — most patients walk the same day, discharge in 2–3 days
• Bone preservation — only damaged tissue is removed; healthy bone stock is maintained
• More natural knee feel — ligaments preserved, kinematics close to original anatomy
• Patient-specific planning — each surgery is planned around your unique anatomy, not a population average
• Future options kept open — bone stock preserved means revision to TKR is straightforward if ever needed

Recovery After RoboLens FT3D

Recovery from RoboLens FT3D knee resurfacing is faster than total knee replacement because less tissue is removed and the healthy parts of the knee are undisturbed. The smaller scope of the procedure means less disruption to surrounding muscle — which directly accelerates the recovery timeline.

• Day of surgery: Walking with support in the recovery room
• Day 2–3: Discharged home. Walking with a frame or stick.
• Week 2: Most patients walk unaided indoors. Drive if left knee operated.
• Week 4–6: Return to work (desk job). Stairs comfortable. Short outdoor walks.
• Month 3–4: Full recovery. Normal walking, shopping, travel. Return to active life.

For patients travelling from outside Chandigarh, the surgery and initial recovery can be completed in a single trip. Most out-of-city patients stay in Mohali for 5 to 7 days before returning home, with physiotherapy instructions for continuation locally.
