Total Knee Replacement

Knee replacement is the procedure international patients most commonly travel to South India for, and it is the one where travelling makes the most straightforward sense. It is planned rather than urgent, the pathway is well established, and the recovery is predictable enough that you can book flights with reasonable confidence. It is also a procedure where the physiotherapy afterwards matters as much as the surgery, which is worth understanding before you choose where to have it done.

What the operation involves

In general terms, total knee replacement removes the worn surfaces of the knee joint and replaces them with metal and plastic components that recreate the joint's movement. It is usually recommended for arthritis that has not responded to medication, injections and physiotherapy, and where pain is limiting ordinary activity.

Partial replacement is an option for some patients where only one compartment of the knee is affected. Whether you are suitable for that, and which implant design fits your anatomy, is a decision for the surgeon after reviewing your X-rays and examining you. Implant choice in particular is frequently oversold in medical-tourism marketing — the sensible question is not which brand but why your surgeon prefers it for your knee.

Why the trip takes as long as it does

The indicative range is around twelve to sixteen days in India. The largest part of that is not the surgery.

Before surgery — two to three days. Fresh X-rays, blood work, an anaesthetic review, and a physiotherapy assessment so the team knows your baseline. Any dental or skin infection needs clearing first, because implant infection is the complication everyone is trying hardest to avoid.

Hospital stay — around three to five days. You will normally be helped to stand within a day of surgery. Early mobilisation is not the hospital rushing you out; it is part of the treatment.

After discharge — a week or so of physiotherapy. This is the reason the trip is two weeks rather than one. Daily supervised physiotherapy in the period immediately after surgery has a real bearing on the range of movement you end up with, and it is much easier to get that consistently while you are still there than to arrange it at home. Your surgeon reviews you before clearing you to fly.

If both knees are being replaced, the timing changes significantly and is a separate conversation — some surgeons stage them, others do both at once, and the recovery looks quite different either way.

What the written estimate covers

You receive an estimate naming the hospital, the consultant orthopaedic surgeon and their medical council registration number, the procedure, the implant being used, an all-inclusive cost range from the hospital and the days to plan for. It typically covers surgery, the implant, theatre time, the ward stay, standard investigations and the inpatient physiotherapy. Flights and the visa fee are not included.

Ask specifically whether the quoted physiotherapy covers the post-discharge period or only the inpatient days — that distinction is where knee-replacement quotes most often differ from one another, and it is easy to compare two estimates that are not actually comparable.

Getting ready to travel

Bring recent weight-bearing X-rays of the knee, any MRI reports, your medication list, and details of previous surgery on that leg. Tell us about diabetes, heart conditions or anything affecting wound healing at the outset rather than on arrival — it changes the pre-operative work-up and occasionally the plan.

Practical things people forget: bring or buy loose clothing that fits over a dressed knee, flat supportive shoes for walking practice, and think about your home in advance. Stairs, bathroom access and whether you have someone at home for the first weeks matter more to your recovery than most of the decisions you will agonise over beforehand.

Questions worth asking the surgeon

• Am I a candidate for partial rather than total replacement?
• Which implant are you using, and why that one for my knee?
• How much physiotherapy is included, and for how many days after discharge?
• What range of movement should I realistically expect at six weeks and six months?
• What are the signs of a problem I should watch for once I am home?
• Who do I contact from abroad if something concerns me?

We will put these to the unit in writing before you travel if you would like the answers on paper.

If something goes wrong

Most knee replacements are uneventful, which is why it is worth being clear about the exceptions before you travel rather than afterwards. The complications that matter most for someone who has travelled are infection of the implant, blood clots, and stiffness that does not respond to physiotherapy — and the common thread is that they usually appear after you have flown home.

Ask the hospital: what their process is if you develop signs of infection once you are back, whether they will review images and correspond with your local doctor, and what a revision operation would involve and cost if one were ever needed. Get the answers in writing. Ask us too, and we will chase them.

Be clear about our role. We are a facilitator — we match you to a hospital, arrange the trip and stay contactable. We do not provide medical care and carry no clinical responsibility for it; your contract for treatment is with the hospital and any clinical claim lies against them under Indian law. That is true of every facilitator in this market whether or not their website mentions it.

Travel insurance rarely covers planned surgery abroad or complications arising from it, and policies that do generally require it to be declared in advance. If you want that protection, arrange it before you travel.

Comparing estimates properly

If you are weighing quotes from several places, make sure you are comparing the same thing. Check whether the implant is specified and included, how many physiotherapy sessions are covered and whether that extends past discharge, whether pre-operative investigations are in the figure, what a longer stay costs per day, and whether the named surgeon is the one who will operate.

Knee replacement quotes vary enormously on physiotherapy alone, and it is the single component that most affects your result. The cheapest number usually has the most carved out of it.

What to expect over the first year

Recovery from a knee replacement is measured in months, and knowing the shape of it in advance prevents a lot of unnecessary worry. Broad expectations, which your own surgeon will refine for you:

Weeks one to six. Swelling and bruising are normal and can be considerable. Walking aids are usual at first. The daily physiotherapy exercises feel tedious and are the single most important thing you do in this period. Sleep is often disturbed, which nobody warns people about.

Six weeks to three months. Most people are walking without aids and managing stairs. Swelling settles gradually. This is where progress feels slower than expected and where people stop doing the exercises, which is the worst possible time to stop.

Three to twelve months. Continued gradual improvement in strength, stamina and comfort. Many people are still noticing small gains at a year.

Some things do not come back. Kneeling is uncomfortable or impossible for a significant proportion of people afterwards, and high-impact activity is generally discouraged for the life of the implant. Ask your surgeon specifically about the activities that matter to you rather than accepting a general reassurance — the answer for gardening is different from the answer for running.

Recovery and going home

You go home with a discharge summary, operative notes including the implant details, imaging, prescriptions and a physiotherapy programme. Keep the implant record safely — you will need it for airport security and for any future medical care involving that joint.

Recovery continues for months rather than weeks, and the physiotherapy you do at home is the part that determines the result. Arrange a local physiotherapist before you travel rather than after you return, and we will make sure the discharge documents give them what they need.
