If you have been told you need a knee replacement, the question on your mind is probably a simple one: how long can you wait? The honest answer depends on which system you are waiting in. Australia’s public hospitals currently ask most patients to wait many months, sometimes more than a year, while private surgery can happen in weeks rather than months if you are willing to pay for it or travel for it. This guide walks through the real wait times, what doctors say about waiting too long, and what a faster, JCI-accredited knee replacement in Thailand actually looks like, from cost to recovery.
How Long Is the Public Waiting List for a Knee Replacement in Australia?
In the public hospital system, a knee replacement is treated as elective surgery, which means it is scheduled rather than urgent. Once your orthopaedic surgeon refers you, you are placed on a waiting list and given a clinical urgency category.
According to data from the Australian Institute of Health and Welfare, half of all patients on the public waiting list for a total knee replacement in 2024 to 2025 were admitted within around 255 days, and almost one in four waited longer than 12 months (AIHW elective surgery waiting times).
| Urgency Category | Clinical Target | What It Means |
|---|---|---|
| Category 1 (Urgent) | Within 30 days | Your condition could deteriorate quickly if surgery is delayed |
| Category 2 (Semi-urgent) | Within 90 days | Some pain and deterioration is expected, but it is not an emergency |
| Category 3 (Non-urgent) | Within 365 days | Minimal risk of rapid deterioration; most standard knee replacements fall here |
Most standard knee replacements are placed in Category 3, which is exactly why the median wait stretches past eight months in many states. Wait times also vary widely by state, region and hospital, so two patients with the same diagnosis can wait very different lengths of time depending on where they live.

How Long Is It Actually Safe to Wait Before Getting a Knee Replacement?
Clinical urgency categories describe how the health system prioritises you, but that is not quite the same question as how long is medically safe. A widely reported study led by researchers at Northwestern Medicine, published in the Journal of Bone and Joint Surgery, followed more than 8,000 patients with knee osteoarthritis for up to eight years.
The study found that roughly 90 percent of people who would benefit from a knee replacement wait longer than they should, often two years or more past the point where they were a good candidate for surgery, while around 25 percent have the operation too soon with little added benefit, as CNN reported on the research.
“Roughly 90% of patients who could benefit from a knee replacement wait longer than they should”: findings reported in the Journal of Bone and Joint Surgery.
Waiting is not free of consequences. The longer arthritis progresses, the more the joint can shift out of alignment, the muscles around the knee weaken from disuse, and overall fitness and mobility decline, all of which make the surgery itself more complex and can affect how well you recover afterward.
What Happens If You Wait Too Long for Surgery?
Delaying a knee replacement you already need does not just mean more time in pain. It tends to compound in a few predictable ways:
- Increased pain and reliance on medication, with less benefit from each dose over time
- Muscle wasting and reduced mobility, which makes rehabilitation slower after surgery
- A knee that has drifted further out of alignment, which can make the operation itself more technically difficult
- Flow-on strain to the hip, the other knee and the lower back from compensating for pain
- Lower overall satisfaction with the surgical outcome compared with patients who did not wait as long
- Knock-on effects on mental health, sleep and independence from months of reduced activity
Public vs Private vs Overseas: Comparing Your Options for a Faster Knee Replacement
Once you understand the wait, the real question becomes what your options actually are. Broadly, Australians facing a knee replacement are choosing between three routes.
| Route | Typical Wait | Estimated Cost (AUD) | What to Know |
|---|---|---|---|
| Public hospital (Medicare) | Roughly 8 months, often over a year | No direct cost to the patient | Free, but the least control over timing and choice of surgeon |
| Private hospital in Australia | Around 4 to 6 weeks once insurance waiting periods are served | Uninsured, around $23,200; insured gap often $1,000 to $5,000+ | Usually requires up to 12 months of prior hospital cover with joint replacement included |
| Knee replacement in Thailand (Medidash Global) | Around 2 to 4 weeks from consultation to surgery | From $13,000 standard, from $20,000 MAKO robotic | JCI-accredited hospitals with full patient support; confirm current pricing and implant inclusions |
The government’s own estimate puts a fully self-funded knee replacement in Australia at around $23,200 once specialist and hospital fees are included (Canstar’s cost breakdown), and even with private hospital cover, most policies only cover joint replacement after a waiting period of up to 12 months. That rarely helps if you need surgery this year and only just took out cover, which is where overseas surgery closes the gap.

Why Australians Are Choosing Bangkok for a Faster Knee Replacement
Medidash Global works with two JCI-accredited partner hospitals in Bangkok. Phyathai 2 International Hospital offers standard total knee replacement from AU$13,000, while KDMS Hospital, Thailand’s first hospital dedicated solely to bone and joint care, offers MAKO robotic-assisted knee replacement from AU$20,000. Both use the internationally recognised implant systems and surgical standards you would expect at home, with the added benefit of surgery scheduled in weeks rather than months.
For patients who want more precision in implant alignment, robotic-assisted surgery uses a 3D model of your own knee to plan the bone cuts and implant placement before the surgeon operates, which can mean a smaller incision and a more personalised fit. If you are weighing up hospitals more broadly, it is also worth reading why one of the world’s best joint replacement hospitals might not be where you think.
What to Expect When You Book Your Knee Replacement in Bangkok
- Initial enquiry and records review: you send your scans, X-rays and surgeon’s notes for a clinical review before you commit to anything
- Quote and scheduling: Medidash Global confirms hospital, surgeon availability and an all-in quote, generally within 2 to 4 weeks of your first enquiry
- Travel and pre-admission: flights, accommodation and hospital pre-admission tests are arranged before you arrive in Bangkok
- Surgery and hospital stay: most patients remain in hospital for several days immediately after a total knee replacement
- Recovery in Bangkok: physiotherapy begins early, and most patients stay in Thailand for one to two weeks of supervised recovery before flying home; see our guide to flying after knee replacement for the details
- Ongoing follow-up: Medidash Global coordinates follow-up check-ins with your surgical team once you are back home in Australia

Frequently Asked Questions about Knee Replacement Waiting Times in Australia
How long is the public hospital waiting for a knee replacement in Australia?
Most patients wait around eight months, though patients in some states and regional areas wait considerably longer, and almost a quarter of patients wait more than 12 months.
Can I skip the public hospital waiting list?
Not for public surgery, but you can move into the private system if you have appropriate hospital cover and have served any waiting periods, or look at options overseas such as a knee replacement in Thailand, where surgery is often scheduled within 2 to 4 weeks.
Is it dangerous to wait too long for a knee replacement?
Waiting itself is not dangerous the way an untreated infection would be, but research shows that most patients who wait past the point of being a good surgical candidate end up with more muscle loss, a harder recovery and lower satisfaction with the result.
Does private health insurance guarantee a fast knee replacement?
No. Even with hospital cover that includes joint replacement, most policies require up to a 12 month waiting period before you can claim, so insurance alone does not solve a wait that starts this year.
How much does a knee replacement cost in Thailand compared with Australia?
A self-funded knee replacement in Australia is estimated at around $23,200 including specialist and hospital fees. Standard knee replacement at Medidash Global’s partner hospital in Bangkok starts from AU$13,000, with MAKO robotic surgery from AU$20,000. Always confirm current pricing and whether the implant is included before booking.
Are hospitals in Thailand safe for knee replacements?
Medidash Global’s partner hospitals are JCI-accredited, the same international standard used by leading hospitals worldwide, and the process covers the full patient journey from initial consultation through recovery and follow-up.
