For an international patient, the estimated package is USD 2,500 to 3,000 for one primary knee replacement and USD 4,000 to 4,500 for bilateral primary knee replacement. The same ranges apply to total knee replacement and unicompartmental or partial knee replacement, when that is the appropriate operation.
That is the short answer. It is not enough to compare providers. You need to know whether a quote is for one knee or two, total or partial replacement, a primary or revision operation, and whether the implant, anaesthesia and inpatient care are included.

First confirm which knee operation is being priced
Total knee replacement, usually shortened to TKR, resurfaces all the main compartments that need treatment. Unicompartmental knee replacement, also called UKA or UKR, treats one suitable compartment. Partial replacement is not a smaller TKR chosen mainly to reduce cost. The arthritis pattern, ligaments, deformity and symptoms must make it appropriate. [4]
Some patients ask for bilateral surgery because both knees are painful. Treating both sides in one planned hospital episode is a separate clinical decision. General health, mobility, home support and the burden of early rehabilitation all matter. A bilateral package price should never be read as confirmation that bilateral surgery is safe for a particular person.
Revision knee replacement is outside these ranges. When an existing implant is loose, infected, unstable or surrounded by bone loss, the required components and reconstruction vary too much for a useful generic package. Revision cases receive a custom estimate after adequate records and assessment.
What the standard surgical package includes
The standard package covers the planned hospital episode from admission to discharge. The usual inpatient stay for a straightforward primary replacement is three days, but discharge depends on pain control, mobility, the wound and general medical recovery.
| Package component | Covered during the planned admission |
|---|---|
| Room | Room rent |
| Materials | Consumables and disposables |
| Medicines | Medicines used during admission |
| Clinical care | Consultations and inpatient physiotherapy |
| Implant | Components stated in the agreed estimate |
| Operation | Theatre, surgeon or doctor and anaesthesia charges |
Travel, visa expenses and additional hotel or apartment stays are outside the standard surgical package. Airport transfer, visa-document support, accommodation and other logistics can be coordinated in a custom package. The dated written hospital estimate confirms the operation and package scope for your case.
What decides where your estimate sits in the range?
The first distinction is laterality: one knee or both. The next is whether this is a standard primary replacement, a partial replacement or a more complex reconstruction. Implant model, fixation, robotic assistance, room plan and medical needs also form part of the final estimate.
Recent weight-bearing X-rays are important. A radiology report or old MRI alone may not show the information needed for alignment, bone loss and compartment-specific planning. The remote scan-review guide explains which records make an early estimate more useful.
The in-person assessment can still change the plan. Examination may show that symptoms do not match the X-ray, that non-surgical care remains reasonable or that a different operation should be discussed. Medical assessment can also affect the safe timing and expected stay. The estimate becomes personal only after those remaining questions are answered.
Bilateral and staged surgery answer different needs
The bilateral range applies when both primary knee replacements are planned during one hospital episode. Some patients may be better served by two operations at different times. Medical fitness, symptom balance, support and the difficulty of early mobility influence that decision.
A staged approach creates two admissions and two recovery periods, so it should not be compared with the bilateral package using the first operation alone. The clinical decision comes before the cost calculation.
How robotic assistance affects the price
The USD 600 robotic supplement applies once to the package. The calculation is USD 2,500 to 3,000 + USD 600 = USD 3,100 to 3,600 for unilateral surgery, or USD 4,000 to 4,500 + USD 600 = USD 4,600 to 5,100 for a bilateral package. These use Dr Vishnu's 29 August 2026 confirmed ranges.
In studies of primary total knee replacement, robotic systems improved radiological alignment on average, but the cited review did not establish better patient scores or fewer complications. Its trials used ROBODOC and NAVIO, so these are not direct CORI or partial-replacement results. [2]
CORI helps the surgeon plan and prepare the bone with a handheld instrument; the surgeon remains responsible for the operation. That describes how the system works, not proof of a better personal outcome. [5]
Suitability and scheduling both matter. CORI-assisted surgery is arranged according to clinical assessment, preoperative clearance, hospital capacity and system availability. Read more about the role of robotics on the robotic knee replacement page.
The implant question needs more than a brand name
The practice may use implants from established global manufacturers such as DePuy Synthes, Zimmer Biomet and Smith+Nephew. A manufacturer name does not tell you the model, bearing design, fixation or whether it suits your anatomy and ligament balance.
Ask which implant or implant category the estimate assumes and when the final choice will be made. Your discharge documents should record the components actually used. Avoid any provider who promises a “lifetime implant” or treats one brand name as proof of a result.
Ask how a partial-replacement plan may change
Suitability for UKA is confirmed through the history, examination, standing images and direct findings. If the disease or ligament condition is more extensive than expected, total replacement may be the safer agreed alternative.
That possibility should appear in the consent and estimate discussion before surgery. It is different from vaguely permitting an unrelated procedure. The patient should know which implants are available and how the final hospital documentation will record the change. [4]
Calculate the complete treatment cost
After checking the hospital package, add pre-travel tests, visa fees, flights, local accommodation, meals, transport, a companion if needed, home physiotherapy, follow-up imaging, insurance and a contingency. Use the full surgery-abroad cost worksheet to separate confirmed costs, expected additional costs and a reserve without double-counting.
Keep enough flexibility for the return date. Hospital discharge is not flight clearance. For an uncomplicated one-sided TKR or UKA, the first reassessment for a flight longer than four hours is usually planned 14 to 21 days after surgery. Bilateral replacement is usually first reassessed at 21 to 28 days. These are practice planning windows, not automatic permission to fly.
Plan care after you return home
Follow-up with Dr Vishnu is included as appropriate for your case. The discharge plan should identify rehabilitation, any planned X-rays and a route to hands-on care at home. Video review supports that handover; a new urgent concern still needs local examination. [3]
The team should provide the operation record, implant details, postoperative images, medicine plan and rehabilitation instructions. The records checklist can help identify a missing document without making you organise the whole handover alone.
How to request your estimate
Send recent weight-bearing knee X-rays, your symptom history, treatments already tried, medicines and important health conditions. Say whether one or both knees trouble you, but leave the choice of operation open until the assessment.
