Knee Replacement in North Bengal: What Makes People Board a Train to Kolkata, and When They Genuinely Don't Need To

Families across North Bengal have travelled to Kolkata for joint replacement for decades, and for a long time that was the right call. What's changed is that the reasons people still give for going are often no longer the real ones. The genuine reasons to travel come down to revision surgery, rare implants and unusual complexity. The rest, which is most knee replacements, is now work an orthopaedic surgery hospital in Siliguri is equipped to do.

Knee osteoarthritis is not a rare problem here. A systematic review of population based studies in India put the prevalence across adults at around twenty per cent, and a separate meta-analysis in the elderly found that close to half of people over sixty are affected. That's a very large number of families making a travel decision.

Here's what actually justifies the journey and what doesn't.

Why did travelling to Kolkata become the default?

Historically, because the surgical volume, the implant availability and the intensive care backup sat there. A knee replacement isn't only an operation. It needs a pre-anaesthetic work-up, an operating theatre with the right air handling, an implant inventory covering several sizes, and an ICU on standby for the patient who has diabetes, heart disease or kidney problems alongside the arthritic knee.

For a long time, that combination wasn't reliably available closer to home, so people went. The habit has outlived some of the reasons for it.

What are the genuine reasons to travel?

Four situations where a referral out is reasonable and worth taking seriously:

• Revision surgery: replacing a knee that was replaced before is a different operation, technically and in terms of what has to be on the shelf. This is the strongest reason on the list.

• Significant deformity or previous trauma: a knee that's badly bowed or one carrying old fracture hardware may need custom or constrained implants and specific planning.

• An infected joint replacement: this needs a unit that handles these regularly, because the treatment runs over months and two operations.

• Serious untreated medical problems alongside: advanced heart failure, dialysis dependence or complex lung disease may need a centre with that specific backup.

What are the reasons that don't hold up any more?

Three that come up constantly:

• "They do more of them there": volume matters, but it's a question to ask the specific surgeon rather than the city. Ask how many knee replacements they perform a year and you'll get a better answer than geography gives you.

• "The implants are better in Kolkata": implants are manufactured by the same global companies and supplied to accredited hospitals across the country. The implant isn't regional.

• "There's no proper physiotherapy here": this one is worth examining carefully, because it's the argument that actually backfires.

Why is physiotherapy the reason to stay rather than go?

Because the surgery is a few hours and the rehabilitation is three months. Whatever happens in theatre, the range of movement you end up with is largely decided by how consistently you do physiotherapy in the first six to twelve weeks.

A family that travels for surgery comes back after five days and then has to arrange rehabilitation locally anyway, usually without any connection to the surgeon who operated. That's the worst version: the operation happens far away and the part that determines the outcome happens close to home, with nobody joining the two.

The practical argument for having surgery and a physiotherapy hospital in Siliguri within reach of each other is that the surgeon reviewing your progress at six weeks is the same one who did the operation, and the physiotherapist can pick up the phone.

What should you actually be asking, wherever you go?

Five questions, and they work equally well in Siliguri or Kolkata:

• How many knee replacements does this surgeon do in a year?

• Is there an ICU in the same building, and who covers it overnight?

• When does physiotherapy start, and is it in the ward or after discharge?

• What's the plan for my diabetes, blood pressure or kidney function around surgery?

• If something goes wrong at week three, where do I go and who sees me?

That last question is where travel starts to look expensive in a way that has nothing to do with the train fare.

What does the picture in Siliguri look like now?

Desun Hospital, Siliguri runs orthopaedics as one of twenty four departments, with anaesthesiology and a critical care and internal medicine unit on site. The hospital is NABH certified and publishes a capacity of 304 beds, with operations launched at 150 initially, including 45 intensive trauma unit beds, 24 ICU beds with ventilator support and 12 step down ICU beds. Round the clock diagnostics sit in the same building for the pre-surgical work-up.

For a straightforward knee replacement in someone whose other conditions are reasonably controlled, that's the set-up the operation actually requires.

If a knee replacement has been advised, get a local orthopaedic opinion before booking travel. Take your X-rays, ask the five questions above, and only travel if the answers genuinely point that way.
