How Much Does a Knee Replacement Cost?
One of the most common questions patients ask is what a knee replacement costs. The honest answer is that it depends — on your insurance, where the surgery is performed, and the implant used. Here is a clear breakdown of the price range, what insurance typically covers, and how to find your own expected out-of-pocket cost.
Key takeaways
- Without insurance, a total knee replacement in the U.S. often runs $20,000–$75,000+, driven largely by the facility (hospital vs. surgery center) and the implant.
- Most patients pay far less: Medicare and most commercial plans cover medically necessary knee replacement — your share depends on your deductible, copay/coinsurance, and out-of-pocket maximum.
- The surgeon’s fee is a small slice of the total; facility fees and the implant make up most of the cost.
- Costs vary by surgical setting, geography, your plan’s contracted rates, and complexity (revision and complex cases cost more).
- Over years of restored function, knee replacement is one of the most cost-effective procedures in medicine — and the decision should hinge on your quality of life, not price.
One of the most common questions patients ask is, “How much does a knee replacement cost?” The honest answer is that it depends — on your insurance coverage, where the procedure is performed, and the type of implant used. Here's a clear breakdown.
The short answer
For patients without insurance, the total cost of a total knee replacement in the United States is often between $20,000 and $75,000 or more. A great deal depends on the setting — a hospital versus an outpatient surgery center — along with the implant used. Most patients, however, do not pay the full amount, because insurance typically covers a significant portion of the procedure. Your final cost varies widely based on your plan, deductible, copayments, and out-of-pocket maximum.
What is included in the cost?
A knee replacement involves much more than the surgery itself. The total cost may include:
- Facility fee — the hospital or surgery center (usually the largest portion)
- The knee implant and surgical supplies
- Anesthesia services
- The surgeon’s fee — typically a small share of the total
- Preoperative testing and medical clearance
- Postoperative imaging
- Physical therapy and rehabilitation
- Follow-up visits
Because multiple providers and facilities are involved, you may receive separate bills for different portions of your care — which is one reason the “total” cost can feel confusing.
The surgeon’s fee is a small piece
Many patients are surprised to learn that the surgeon's fee is usually only a small percentage of the overall cost. The facility fee and the implant drive most of the price — which is also why where the surgery is performed matters so much.
Does insurance cover knee replacement?
In most cases, yes.
Medicare and most commercial insurance plans cover knee replacement when it is considered medically necessary. That generally means:
- You have advanced knee arthritis or joint damage
- Your symptoms are affecting your quality of life
- Conservative treatments have failed to provide adequate relief
Even when insurance covers the procedure, you may still be responsible for a deductible, copayments, or coinsurance depending on your specific plan. Demonstrating that you've tried nonsurgical treatment first — activity modification, anti-inflammatories, physical therapy, and injections — is often part of meeting the medical-necessity requirement.

Why do costs vary so much?
Several factors influence the overall cost:
Where the surgery is performed
A knee replacement can be performed in a hospital or an outpatient surgery center, and costs may differ significantly between facilities. For healthy, appropriately selected patients, the same-day outpatient setting often carries lower facility overhead.
Geographic location
Healthcare costs vary across different regions of the country.
Insurance contract rates
Every insurance company negotiates different reimbursement rates with hospitals, surgery centers, and physicians — so two patients can have very different bills for the same operation.
Complexity of surgery
Revision knee replacements, severe deformity, prior knee surgery, or significant medical conditions can increase the overall cost.
How to find your own expected cost
The single best way to get an accurate number is to ask — before surgery, not after. A few practical steps:
- Call your insurer with the procedure (CPT) code and ask for your estimated out-of-pocket cost
- Ask the facility for a written cost estimate — many hospitals now publish online price estimators
- Confirm whether your deductible has been met for the year
- Ask whether your surgeon and facility are in-network for your plan
Price transparency is on your side
U.S. hospitals are now required to publish their prices, and Medicare's Procedure Price Lookup lets you compare typical costs between hospital and surgery-center settings. Our team can also help you understand your coverage before you commit to anything.
Is knee replacement worth it?
For patients with severe arthritis, knee replacement is consistently one of the most successful procedures in all of medicine. Many patients experience:
- Significant pain relief
- Improved walking ability
- Better sleep
- Increased independence
- A return to activities like golf, travel, swimming, and exercise
Viewed over many years of improved function and quality of life, knee replacement is often considered one of the most cost-effective procedures available — and modern implants are built to last, as covered in how long a knee replacement lasts.

Frequently asked questions
How much does a knee replacement cost without insurance?
For patients without insurance, the total cost in the United States is often between $20,000 and $75,000 or more. A great deal depends on the setting — a hospital versus an outpatient surgery center — along with the implant used and your region. Most patients, however, do not pay the full amount because insurance covers a significant portion.
Does insurance or Medicare cover a knee replacement?
In most cases, yes. Medicare and most commercial plans cover knee replacement when it is medically necessary — meaning you have advanced arthritis or joint damage, your symptoms affect your quality of life, and conservative treatments have not provided adequate relief. You may still owe a deductible, copay, or coinsurance depending on your plan.
How much will I actually pay out of pocket?
Your out-of-pocket cost depends on your specific plan — your deductible, copayments, coinsurance, and annual out-of-pocket maximum. The best way to get an accurate number is to call your insurer with the procedure (CPT) code and ask the facility for a cost estimate. Many hospitals now publish price estimators online as well.
Why is an outpatient (surgery-center) knee replacement often less expensive?
Ambulatory surgery centers generally have lower facility overhead than hospitals, which can reduce the total cost for appropriately selected, healthy patients who go home the same day. Whether the outpatient setting is right for you depends on your overall health and support at home.
What is included in the cost of a knee replacement?
The total typically includes the facility (hospital or surgery center) fee, the implant and surgical supplies, anesthesia, the surgeon’s fee, preoperative testing, postoperative imaging, physical therapy, and follow-up visits. Because several providers are involved, you may receive separate bills for different parts of your care.
Is a knee replacement worth the cost?
For patients with severe arthritis, knee replacement is consistently one of the most successful and cost-effective procedures in all of medicine. Measured over many years of pain relief, restored mobility, and quality of life, the value is substantial — which is why the decision should center on how much arthritis is limiting your life, not on price alone.

How Long Does a Knee Replacement Last?
Knee replacement is one of the most successful operations in modern medicine, and today’s implants are built to last for decades. Long-term data show that more than 75% of knee replacements remain intact at 30 years. Here is an honest look at how long they last, what influences longevity, and why “you’ll need another one in 10 years” is largely a myth — without overpromising.

For many patients today, a hip or knee replacement no longer means a hospital stay. Outpatient — or same-day — joint replacement lets appropriately selected patients recover in the comfort of their own home the same day as surgery. It’s made possible by modern, muscle-sparing technique and recovery protocols, not by cutting corners — and you go home only when you’re truly ready. Here is what it involves and who it suits.

One of the most common questions I hear is whether someone is too young — or too old — for a hip or knee replacement. The answer surprises many patients: the decision is rarely about age at all. It’s about how much arthritis is affecting your life, your overall health, and whether conservative treatments still help.
