Last updated: September 2026

Reviewed for medical accuracy by Dr Ye Aung, Specialist Assistant Physician, Gastroenterology Department, Yangon General Hospital. Last reviewed September 2026.

Quick summary

• Knee replacement packages at three partner hospitals in Bangkok run from 283,000 THB for a standard total knee replacement to 647,000 THB for robotic-assisted surgery. Implants are included in every knee package.
• The hospitals are Bumrungrad International Hospital, Phyathai 2 Hospital and KDMS Hospital, Thailand's first hospital dedicated exclusively to bone and joint conditions.
• The published KDMS inpatient stay is 5 days and 4 nights for one knee.
• NHS guidance puts the move from crutches to unaided walking at around six weeks, with full recovery taking several months or longer.

Who needs a knee replacement

Knee replacement is generally the treatment for end-stage osteoarthritis once non-surgical management has failed, not a first step. That framing comes from the 2019 Lancet analysis of registry data, and it matches what your surgeon will tell you at assessment.

The typical candidate has advanced osteoarthritis, rheumatoid arthritis or post-traumatic damage, has already tried physiotherapy, weight management, medication or injections, and still has pain that limits daily life. NICE guidance (NG157, 2020) recommends that anyone offered a joint replacement receives full information on their options, including anaesthesia, and that the decision follows shared decision-making principles.

Whether you are a candidate is decided by assessment, not by a website. Send recent X-rays and your medical history and the orthopaedic team will tell you. If you are not a suitable candidate, we will tell you honestly.

Types of knee replacement available in Bangkok

Four options are available through our partner hospitals, and your imaging decides which is appropriate, not the price list.

Total knee replacement. The damaged surfaces of the whole joint are replaced. This is the standard operation for end-stage osteoarthritis and the lowest-priced package, from 283,000 THB.

Partial (unicompartmental) replacement. Only the damaged compartment is resurfaced. Registry data puts around 70% of partial replacements still in place at 25 years, against around 82% for total replacements. Your surgeon decides which is appropriate from your imaging.

Robotic-assisted replacement. A robotic arm guides the bone cuts to a plan built from a CT scan of your knee. Available at KDMS and Bumrungrad. The evidence on what this buys you is covered honestly below.

Bilateral replacement. Both knees in one operation, one anaesthetic and one recovery period. Offered at Phyathai 2. It is a bigger operation and not everyone is a candidate.

Revision surgery, the replacement of a previous implant, is also performed in Bangkok, but it falls outside standard package pricing and is always quoted individually.

How the surgery is done

The surgeon removes the damaged surfaces of the thigh bone and shin bone, then fits an implant in their place so the joint moves on smooth artificial surfaces rather than damaged cartilage and bone.

Anaesthesia options are discussed at assessment. NICE recommends that patients receive full information on anaesthesia choices as part of shared decision-making, so ask what is proposed for your case and why.

On implants: KDMS publishes that its packages use Stryker implant components from the United States. The other hospitals confirm the implant in your written quote. Ask for the brand and model in writing. Registry survivorship data is published per implant, so knowing the model means you can look up how it has performed.

For robotic-assisted patients, a CT scan is taken before surgery to build a three-dimensional model of the knee for surgical planning.

Robotic-assisted vs conventional

The evidence supports better precision, not better outcomes, at least so far. A 2025 analysis of 21 randomised trials covering 2,692 patients found robotic-assisted surgery achieved better mechanical alignment than conventional surgery, but did not show superior short to medium-term functional outcomes, and took longer in theatre.

There is no evidence yet that robotic knees last longer, and long-term cost-effectiveness is not established. Some patients value the precision; it is a reasonable choice either way. The full trade-off is covered on the robotic-assisted knee replacement page.

Where to have it done in Bangkok

We work with three hospitals for knee replacement, and the right one depends on your case, not on a ranking.

KDMS Hospital. Thailand's first hospital dedicated exclusively to bone and joint conditions, opened in 2022 and founded by orthopaedic surgeons and rehabilitation doctors. Lowest knee entry price and the lower of the two robotic price points. Not the right choice for patients with significant other medical conditions who may need a multispecialty hospital.

Phyathai 2 Hospital. JCI-accredited since 2014, a large multispecialty hospital with 550 beds, established in 1987, and the only partner offering a bilateral package. The mid-priced option. Not the right choice if you want robotic-assisted surgery; our packages there are conventional only.

Bumrungrad International Hospital. The first hospital in Asia to receive JCI accreditation, in 2002, with its seventh re-accreditation in January 2024. The largest international patient infrastructure of the three, at the highest price point. Not the right choice if price is the deciding factor.

What it costs

Prices last verified: September 2026. Approximate conversions at September 2026 rates. Your bank's rate on the day will differ.

Every knee package includes the implant. A package price assumes a straightforward case: KDMS states that its package applies to patients without complicating conditions, and that patients classed ASA III or above, or whose surgery is more complex or longer than standard operating time, fall outside package pricing. Assume the same principle at any hospital.

Flights, hotel for the outpatient recovery period, extra hospital nights, outpatient physiotherapy after discharge, treatment of complications and travel insurance are not included. The cost page has the full breakdown and a worked trip budget.

The timeline

The process runs in six stages. Day counts are deliberately absent where no verified figure exists; your surgeon and your written plan set the dates.

1. Enquiry. You send your X-rays, medical history and situation through the form or WhatsApp. A coordinator responds.
2. Free virtual consultation. A video consultation at no cost. Suitability is assessed and a recommendation made between conventional and robotic-assisted surgery based on your anatomy and goals.
3. Written treatment plan. You receive the recommended hospital, procedure details, timeline and complete written pricing. Nothing is committed at this point.
4. Arrangements. Once you confirm, the coordinator arranges the surgery date, accommodation close to the hospital, airport transfers and hospital registration. You book your own flights; choose a flexible return fare.
5. Arrival, assessment and surgery. Pre-operative assessment including infection screening, a CT scan if your surgery is robotic-assisted, then surgery by the orthopaedic team. The published KDMS stay is 5 days and 4 nights for one knee.
6. Rehabilitation and return. Walking training begins the day after surgery. In-hospital physiotherapy continues through the stay, then outpatient physiotherapy and wound checks until your surgeon clears you to fly.

Medidash Global can usually arrange surgery within two to four weeks of enquiry, subject to assessment and hospital scheduling. That is a logistics figure, not a clinical one.

Recovery and physiotherapy

The NHS recovery guidance is the honest baseline, and it is slower than most medical travel sites suggest.

• Stitches or clips are removed after about 10 days.
• Use crutches or sticks at first; try walking without an aid after about six weeks if you are ready.
• Wait at least six weeks before driving after a total knee replacement, three weeks after a partial, and check with your doctor first.
• In the early weeks, get up and walk for five minutes every hour to reduce blood clot risk.
• Full recovery can take several months or longer, varying with age and general health.

The American Academy of Orthopaedic Surgeons advises continuing prescribed physiotherapy exercises for at least two months after surgery, with return to work ranging from several days to several weeks depending on the job. In-hospital physiotherapy is included in your package; outpatient sessions after discharge usually are not, so budget for them in Bangkok or at home.

On flying home: UK guidance suggests waiting around three months before long-haul flying after a joint replacement, mainly because of blood clot risk. International patients treated in Bangkok are typically assessed for fitness to fly by their surgeon before discharge, prescribed anticoagulation, fitted with compression stockings and given an in-flight movement plan. The timing is set by the surgeon, not by the package. Plan for the longer stay your surgeon recommends.

Risks, complications and what happens if something goes wrong

Knee replacement is major surgery with well-documented risks. Stating them plainly is the point of this site.

Infection. Periprosthetic joint infection after a primary total knee replacement is generally estimated at between 1% and 2%, per a 2025 meta-analysis. Confirmed risk factors include longer operating time, obesity, diabetes, male sex, a longer hospital stay, immunosuppressant use, low albumin and systemic inflammatory disease. One study of 304 patients found most infections occurred within the first six weeks after surgery, which is the main argument for a proper recovery period rather than the earliest possible flight.

Revision. In the American registry, matched implant data shows an overall 10-year revision rate of about 2.13% for cemented total knees, roughly one in fifty. Infection is the leading cause of revision in the US registry, accounting for 52% of revision knee procedures in the 2025 report; aseptic loosening is second at 29%.

Other risks include blood clots, stiffness and implant loosening over time. NHS early-recovery advice to walk five minutes every hour exists precisely because of clot risk.

What if it goes wrong? What a package covers if something goes wrong varies by hospital and is set out in the package terms, not the headline price. Before paying, get written answers to three questions: what is covered if a complication is treated before you leave Thailand, what happens if a problem appears once you are home, and who pays for a revision if one is needed. Medidash Global obtains these terms in writing for any package we quote.

After you fly home, the hospital provides a full surgical report covering implant materials, operative notes and post-surgical recommendations. You take that record to your own GP or specialist, and the coordinator helps arrange follow-up physiotherapy at home and remains reachable. A surgical record is documentation, not cover; the package terms above are what determine who pays for what.

Thai private hospitals do not publish procedure-level outcome data the way the UK, Australian and US registries do. Ask any hospital for its knee replacement volume and its infection and revision rates for the past three years. A hospital that tracks these numbers will give them to you; one that will not is telling you something too.

How long a knee replacement lasts

Pooled registry data published in The Lancet in 2019, covering roughly 300,000 total knee replacements across five national registries, found that around 82% were still in place at 25 years, and around 70% of partial replacements.

Two caveats belong next to that figure. "Still in place" means the implant had not been revised; it is not a personal probability for any individual. And the older "15 to 20 years" figure you may have read reflects implants from an earlier era, though the newer number does not apply automatically to every implant or every patient.
