Most patients choose a surgeon the way they choose a restaurant, by rating and proximity. Neither tells you what you actually need to know. Here is what does.
Ignore the word best
No register, board or authority certifies anyone as the best orthopaedic surgeon in Mumbai. Where you see that phrase, it was bought or self-applied. The same is true of rankings and award badges. They are marketing assets, not evidence, and treating them as evidence is how patients end up in the wrong theatre.
Check registration and current practice
Verify qualifications on the relevant medical register rather than on a website. Then ask the question that actually matters, which is whether your specific operation is a regular part of that surgeon's present practice. A general orthopaedic surgeon who does a handful of knee replacements a year is not the same proposition as one who does them weekly.
Judge the consultation, not the equipment
A good assessment establishes the cause of your pain and what it is costing you in walking, stairs, sleep and work. If a replacement is advised from a line on an MRI report without that conversation, the assessment was not done.
Robotic assistance belongs in this conversation but not at the centre of it. It supports planning and execution. It does not diagnose you and it does not operate on its own. A surgeon who leads with the robot rather than with your diagnosis has told you something about their priorities.
Four red flags
Guaranteed painless surgery. A guaranteed implant lifespan. Pressure to book a date before the diagnosis is settled. Claims that established arthritis can be reversed or regenerated. Any one of these is reason enough to seek another opinion.
One more test. Ask what happens if you decide not to operate. A surgeon who can describe that path properly, with what it costs you and what it preserves, is thinking about your knee rather than their list. One who cannot, or who treats the question as obstruction, has shown you how the rest of the relationship will go.
