Does the robot perform the surgery?

No. This is robotic-assisted surgery. Planning, every decision during surgery and the operation itself remain in the surgeon's hands. The system provides measurements during surgery and holds the cutting guide in the planned position; it does not act on its own.

Is robotic knee replacement more expensive?

It may cost more than a conventional knee replacement, mainly because of the use of the robotic system and any extra imaging. PMG Hospital gives a written, itemised estimate before admission, which shows the cost for your operation.

Am I a candidate for robotic surgery?

Robotic assistance is an option for many people having their first knee replacement for arthritis. Whether it is used for your knee is decided after an examination and X-rays, and it does not change whether you need a knee replacement in the first place.

Is recovery genuinely faster?

Recovery follows broadly the same timeline as after a conventional knee replacement. Randomised trials have found similar function scores with either method, so robotic assistance should not be relied on for a quicker recovery.

Robotic Assistance That Measures the Knee, While the Surgeon Operates

When a robotic system is used in knee replacement, it helps the surgeon take measurements of the knee and position the cutting guides during the operation, while the surgeon still plans and carries out every step. At PMG Hospital in Gota, Ahmedabad, the ROSA Knee System is used for robotic-assisted knee replacement where it suits the knee. The implants, the hospital stay and the recovery are broadly the same as for a conventional knee replacement. A 2024 analysis of randomised trials found that robotic assistance gave alignment closer to the target on X-rays taken after surgery, while function scores and complication rates were similar to those of conventional surgery.

The division of work

What the Robot Does and Does Not Do

The robotic system	The surgeon
Records landmarks of the knee at the start of the operation	Decides whether a knee replacement is needed at all
Measures the gaps and ligament tension as the knee bends and straightens	Plans the implant size, position and leg alignment
Shows the measurements against the plan during surgery	Decides whether the plan needs to be changed during the operation
Holds the cutting guide in the planned position	Cuts the bone and places each implant component

Step by step

Robotic Knee Replacement in Ahmedabad: Step by Step

1. Planning

Standing X-rays are used before surgery to plan the implant size and the alignment of the leg; in some cases, the plan is built during the operation without pre-operative images.

2. Mapping the Knee

At the start of the operation, small tracking markers are fixed to the bones, and key points on the knee are recorded so that the system has a record of its shape.

3. Balancing the Ligaments

The knee is moved through its range, and the gaps between the bones are measured in millimetres and degrees, helping the surgeon balance the ligaments.

4. Guided Bone Cuts

The robotic arm holds the cutting guide in the planned position; the surgeon makes each cut and fits each part of the implant.

At PMG Hospital, robotic assistance forms one part of TriNova; the other two parts are entering the knee beneath the vastus medialis muscle (subvastus approach) and operating without a thigh tourniquet.

Research

What the Research Shows

A 2024 analysis that combined randomised trials comparing robotic-assisted and conventional total knee replacement found that robotic assistance placed implants closer to the planned alignment on X-rays taken after surgery. The same analysis found similar function scores and complication rates with the two methods. Longer-term studies are still needed to show whether the closer alignment leads to longer-lasting implants.

Who it suits

When Robotic Assistance May Be Considered

Knee situation	Points to know
Primary knee replacement for arthritis (no earlier implant)	Robotic assistance can be used in many such knees
A marked bow-leg or knock-knee deformity	Measurements during surgery may help the surgeon plan the correction
A straightforward knee with little deformity	A conventional knee replacement is usually suitable

The decision to use the robot for your knee is taken once you have been examined and your X-rays studied.

Recovery

Recovery After Robotic-Assisted Knee Replacement

Using the robot does not change the general course of recovery. Most people start walking with support soon after surgery, and the hospital stay and physiotherapy programme depend on the type of knee replacement done.

Total knee replacement

Risks

Risks to Discuss Before Surgery

The risks are those of any knee replacement, including infection, blood clots, stiffness and, rarely, injury to nerves or blood vessels. Specific to robotic assistance:

Small extra incisions may be needed where the tracking markers are fixed to the bones
Rarely, infection or a fracture at a marker site
The operation may take a little longer than a conventional knee replacement

Cost

Robotic Knee Replacement Surgery Cost in Ahmedabad

The cost of robotic knee replacement surgery in Ahmedabad depends mainly on:

The type of operation and the implant chosen
The use of the robotic system
Any extra imaging needed for planning
The room category and the number of days in hospital
Physiotherapy and follow-up visits

Questions

Questions to Ask a Robotic Knee Replacement Doctor in Ahmedabad

Whichever robotic knee replacement doctor in Ahmedabad you consult, these questions help you make an informed decision:

Do I need a knee replacement, and which type?
Will robotic assistance be used for my knee, and why?
How does it change the cost of my operation?
Will my recovery plan differ from a conventional knee replacement?

The care team

Robotic Knee Replacement Surgery Doctor in Ahmedabad

A robotic knee replacement surgery doctor in Ahmedabad is an orthopaedic surgeon whose training covers joint replacement (arthroplasty) and who has also learned to work with the robotic system in use. The robot remains an instrument in the surgeon’s hands, and a wider team looks after you from the first examination until you are walking at home:

Stage	Who is involved	What they do
Deciding on surgery	Orthopaedic surgeon	Assesses the knee on examination and on standing X-rays, then judges whether a replacement is needed and whether robotic assistance suits that knee
Fitness check	Physician or cardiologist	Checks blood pressure, diabetes, heart health and regular medicines such as blood thinners, which matters most in older patients
Imaging	Radiologist	Reports the X-rays and any further scan asked for during planning
Anaesthesia	Anaesthetist	Gives a spinal or a general anaesthetic; a nerve block is commonly added to ease pain after the operation
In the operating theatre	Orthopaedic surgeon and theatre team	The surgeon records the knee landmarks, reads the measurements and makes every bone cut; the robotic arm only steadies the cutting guide at the planned position
Recovery	Physiotherapist	Begins standing, walking and knee-bending exercises and sets the programme to follow at home

When robotic assistance is offered, you may also ask who will look after your pain relief on the ward and who will check your progress in physiotherapy after discharge.
