Knee pain that limits your daily life — climbing stairs, walking to the market, or even getting out of a chair — is more than discomfort. When conservative treatments like physiotherapy, injections, and medications stop working, knee replacement surgery becomes the logical next step. But now, a newer option has arrived in Panvel: robotic-assisted knee replacement.
In this article, Dr. Juilee Mhatre Nair — orthopaedic surgeon and robotic joint replacement specialist at Mhatre Accident Hospital — answers every common question patients ask before choosing this procedure.
What Is Robotic Knee Replacement?
Robotic knee replacement is not a robot performing surgery on its own. Instead, it is a surgeon-controlled, computer-guided system that assists the orthopaedic surgeon in making precise bone cuts and placing the knee implant with extraordinary accuracy.
Before surgery, a 3D CT scan of your knee is taken. The robotic system uses this scan to create a personalised virtual model of your joint. During surgery, the surgeon uses a robotic arm that gives real-time feedback — ensuring that every cut stays within the pre-planned boundaries, unique to your anatomy.
How the Robotic System Works — Step by Step
- Pre-op CT scan creates a 3D map of your knee joint
- Surgeon plans the exact implant size, position, and alignment on screen
- Robotic arm guides bone cuts to within 0.5 mm of the plan
- Real-time feedback alerts the surgeon if any movement strays off plan
- Implant is fixed; surgeon verifies alignment before closing
Robotic vs. Conventional Knee Replacement: What's the Difference?
Conventional knee replacement has a proven 15–20 year track record and is still an excellent operation. So why consider robotic?
Who Is a Good Candidate?
Robotic knee replacement is suitable for most patients who are candidates for conventional total knee replacement. You may be a good candidate if you have:
You May Benefit If You Have…
- Severe osteoarthritis of the knee (Grade 3 or 4)
- Rheumatoid arthritis with significant joint destruction
- Persistent knee pain limiting daily activities
- Failed conservative treatment (3–6 months)
- X-ray showing significant joint space narrowing
- Age between 50–80 (also considered for younger, active patients)
May Not Be Suitable If…
- Active infection in or around the knee
- Severe osteoporosis without adequate bone stock
- Uncontrolled diabetes or cardiac conditions (surgery deferred)
- Knee pain caused by non-arthritic conditions
- BMI >40 (weight reduction advised first)
The only way to know for certain is a thorough evaluation — X-rays, blood tests, and a consultation with our orthopaedic team.
Recovery Timeline: What to Expect Week by Week
Recovery from robotic knee replacement is faster than most patients anticipate. Here is a general timeline:
First steps with support
Most patients stand and take a few assisted steps within 12–24 hours of surgery. Our physiotherapist starts gentle knee bending exercises the same day.
Home with a walker
Patients are discharged after 2–3 days. You will walk with a walker, manage stairs with assistance, and continue home physiotherapy exercises twice daily.
Transition to a cane
Most patients graduate from a walker to a single cane. Swelling reduces significantly. Knee bending typically reaches 90°–100° by this point.
Walking unaided
The majority of patients are walking independently without any aid. Returning to driving, light shopping, and social activities is typical at this stage.
Full functional recovery
Patients can resume most daily activities including light exercise, yoga (modified), and travel. The new joint continues to strengthen over the following year.
5 Questions to Ask Your Surgeon
Before agreeing to any knee replacement, ask your surgeon these five questions:
-
How many robotic knee replacements have you performed?
Experience matters. Our lead surgeon has performed hundreds of joint replacements and is fellowship-trained in robotic techniques.
-
Which robotic system do you use, and why?
Different systems have different strengths. Your surgeon should explain the platform and why it suits your anatomy.
-
Will I need a blood transfusion?
Robotic surgery is associated with significantly less blood loss — many patients at our centre do not require transfusion.
-
What implant brand will be used, and what is its track record?
We use internationally certified implants with well-documented 15–20 year registry data.
-
What does the physiotherapy plan look like?
A structured rehab plan is as important as the surgery itself. Our in-house physiotherapy team begins the protocol on day one.
