What each price includes
- Australia: National efficient price, public hospital (minor complexity). The whole public hospital admission: the operation, implant or device, nursing, medicines and an average length of stay for that type of admission. Public patients in Australian public hospitals pay nothing: the national efficient price is what governments use to fund the hospital.
- United Kingdom: NHS national unit price (fewest other health problems). The whole hospital stay for the operation: surgery, theatre, the implant or device, nursing, medicines and a normal length of stay. Very long stays get an extra daily payment. NHS patients do not pay this price: NHS hospital treatment is free at the point of use for people who live in the UK.
About knee replacement
Total knee replacement (total knee arthroplasty) removes the damaged surfaces of the knee joint and replaces them with metal and plastic implant parts. Surgeons usually recommend a knee replacement when severe arthritis or injury causes pain and stiffness that no longer respond to other treatment. The operation typically takes one to two hours. Depending on the country and hospital, patients stay between zero nights (same-day surgery) and several days, followed by weeks of physiotherapy. The total bill is driven by the implant, the hospital stay, the surgeon and anaesthetist fees, and rehabilitation.
Before travelling for treatment, also budget for flights, accommodation, recovery time and follow-up care, and check the hospital's accreditation and whether your insurance covers treatment abroad.
