How Much Does Knee Replacement Surgery Cost in 2026?

Roughly 790,000 or more knee replacements are performed in the United States each year, making it one of the most common major orthopedic procedures – and demand is projected to keep climbing as the population ages. Yet the knee replacement surgery cost still surprises many patients when they see the numbers. As of early 2026, a total knee replacement without insurance typically ranges from $30,000 to $50,000, though prices at some facilities exceed $70,000. Even with good insurance, out-of-pocket costs can run roughly $3,000 to $10,000 or more depending on your plan’s deductible and coinsurance structure. All of these numbers are estimates that vary widely by hospital, region, and your specific health plan, so treat them as ballpark figures rather than a quote. For a broader perspective on surgical costs in the US system, our complete healthcare costs guide covers pricing across dozens of procedures.

Average Knee Replacement Cost in 2026

According to data and pricing patterns tracked by the Centers for Medicare & Medicaid Services (CMS), the average total cost of knee replacement surgery – including surgeon, facility stay, anesthesia, implant, and post-operative rehabilitation – generally ranges from about $30,000 to $50,000 at most hospitals as of early 2026. Medicare’s reimbursement for a total knee arthroplasty is substantially lower than hospital list prices, which gives a useful reminder that the “chargemaster” number a hospital publishes is rarely what anyone actually pays.

Partial knee replacement (unicompartmental arthroplasty), which resurfaces only the damaged compartment of the knee rather than the entire joint, tends to cost roughly 20% to 30% less – often $20,000 to $35,000 before insurance. Partial replacements involve a smaller implant, shorter surgical time, less blood loss, and a faster recovery, all of which contribute to lower costs. However, not all patients are candidates – the condition of all three knee compartments must be evaluated to determine eligibility, and that decision is a clinical one made with your surgeon.

Bilateral knee replacement (both knees in a single surgery) costs more per session – typically $45,000 to $70,000 – but can save money compared with two separate surgeries when you factor in two facility admissions, two rounds of anesthesia, and two rehabilitation periods. Most surgeons reserve simultaneous bilateral replacement for relatively healthy patients who can tolerate the longer procedure and more demanding recovery, and the decision depends on your individual risk profile, not cost alone.

Knee Replacement Cost With Insurance vs. Without Insurance

Unlike cosmetic procedures, knee replacement is almost always considered medically necessary and is covered by insurance when conservative treatments (physical therapy, injections, anti-inflammatory medications, bracing, and activity modification) have failed to control pain and disability. The financial difference between insured and uninsured patients is dramatic.

Without Insurance

Uninsured patients face the full billed charge, which can range from roughly $30,000 to $70,000 depending on the hospital. However, most hospitals offer significant self-pay discounts – often 30% to 60% off the chargemaster (listed) price – and you generally have to ask for them. Facilities that participate in bundled pricing programs may offer an all-inclusive package, frequently in the $15,000 to $30,000 range, covering everything from pre-operative evaluation through roughly 90 days of post-operative care including physical therapy. The Healthcare Bluebook “fair price” for total knee replacement has historically sat in the mid-$20,000s, which represents a reasonable benchmark for what well-informed self-pay patients might aim to pay; check the current figure for your ZIP code, since these benchmarks are updated over time.

A number of transparent, cash-pay surgery centers around the country now advertise all-inclusive bundled prices for joint replacement online, sometimes well below hospital averages. Patients who are willing to travel can access these lower prices, though they should factor in travel costs, lodging during recovery, and the logistics of arranging post-operative follow-up care with a local provider. Always confirm exactly what a “bundle” includes – implant, anesthesia, facility fee, and follow-up – before assuming it is complete.

With Insurance

Most commercial insurance plans cover knee replacement after documentation of failed conservative treatment. Insurers typically require evidence of at least 3 to 6 months of non-surgical treatment (physical therapy, injections, medication) before authorizing surgery, along with imaging showing significant joint damage. This is called prior authorization, and skipping it can leave you responsible for the bill.

Your out-of-pocket cost typically includes your annual deductible (commonly $1,000 to $5,000 or more for many plans) plus coinsurance (often around 20% of the allowed amount). For a procedure with an allowed amount of $30,000 and 20% coinsurance after a $3,000 deductible, you would owe roughly $8,400 – unless you hit your out-of-pocket maximum first, which caps your total exposure for the year. Many patients reach their out-of-pocket maximum with knee replacement, effectively capping in-network costs somewhere in the $6,000 to $9,000 range for most plans. Understanding your plan’s out-of-pocket maximum is the single most important step in predicting your actual cost.

What’s Included in the Total Cost?

Knee replacement bills are complex because they involve multiple providers and service categories. Understanding each component helps you anticipate – and potentially negotiate – the total. The ranges below are estimates and vary considerably by facility.

• Surgeon’s fee: roughly $5,000 to $10,000 for the orthopedic surgeon performing the procedure
• Hospital/facility fee: roughly $15,000 to $30,000, which includes the operating room, nursing care, medications, and any facility stay (often same-day discharge to 1-2 nights)
• Anesthesia: roughly $2,000 to $4,000 for anesthesia services (general, spinal, or regional anesthesia)
• Implant (prosthetic): roughly $3,000 to $12,000 depending on the manufacturer, material, and whether it’s a standard or custom-designed implant
• Physical therapy/rehabilitation: roughly $2,000 to $5,000 for post-operative rehabilitation (often 6-12 weeks of outpatient PT)
• Pre-operative testing: roughly $500 to $1,500 for imaging, blood work, cardiac clearance, and medical optimization

If you need pre-operative MRI imaging to assess soft tissue damage or surgical planning, that adds to the total. Post-operative durable medical equipment (knee brace, walker, ice therapy device) can add a few hundred to about $1,000. Ask your surgeon’s office for a comprehensive cost estimate that covers all expected expenses through your full recovery period, including projected physical therapy sessions.

Cost by Location and Facility Type

Hospital pricing for knee replacement varies enormously even within the same city – a fact that frustrates patients and health economists alike. An academic medical center might charge $50,000 to $70,000, while a specialized orthopedic surgery center across town charges $20,000 to $30,000 for the same procedure performed by an equally qualified surgeon. Publicly available price data has repeatedly shown that charges for the same knee replacement can vary several-fold between hospitals in the same metro area.

Regional trends are fairly predictable: Northeast and West Coast hospitals tend to charge more than many Southeastern and Midwestern facilities. However, the biggest savings often come from choosing an ambulatory surgery center (ASC) over a hospital. Select patients – those who are relatively healthy, have adequate home support, and aren’t at high risk for complications – can have knee replacement performed as an outpatient at an ASC, potentially reducing facility costs by 30% to 50%. The shift toward outpatient knee replacement has accelerated over the past several years; CMS removed total knee replacement from the Medicare inpatient-only list in 2018 and later allowed it to be performed in ambulatory surgery centers, and private insurers have followed suit.

Illustrative metro-area hospital ranges (chargemaster prices before insurance negotiation or self-pay discounts) have historically looked something like: New York City ($45,000 to $70,000), Los Angeles ($40,000 to $60,000), Chicago ($30,000 to $50,000), Houston ($28,000 to $45,000), and Atlanta ($25,000 to $40,000). Use these only as a rough sense of variation, not a quote for your situation.

Knee Replacement Cost With Medicare in 2026

Medicare covers knee replacement when it is medically necessary. Under Original Medicare, Part A covers any inpatient hospital stay and Part B covers the surgeon’s fee and outpatient services (including outpatient surgery-center procedures and rehabilitation). For 2026, the Medicare figures that shape your cost are hedged official numbers you should confirm at Medicare.gov, but as published they include a Part A inpatient hospital deductible of $1,736 per benefit period and a Part B annual deductible of $283, after which Part B generally pays 80% and you are responsible for 20% coinsurance with no annual out-of-pocket cap under Original Medicare alone. The standard Part B monthly premium for 2026 is about $202.90 (higher for higher-income enrollees).

Because Original Medicare has no out-of-pocket maximum, many beneficiaries carry a Medigap (Medicare Supplement) policy – plans such as Plan G – that can reduce your share of a knee replacement to very little, sometimes only the Part B deductible. Medicare Advantage plans instead bundle coverage with their own copays, networks, and an annual out-of-pocket maximum, so knee-replacement costs on those plans vary by plan but are capped for the year. Whether the surgery is billed as inpatient or outpatient can also change which deductible applies, so ask how your procedure will be classified.

How to Save Money on Knee Replacement

Start by verifying that all providers involved – surgeon, anesthesiologist, any assistant surgeon, and the facility – are in-network with your insurance plan. Out-of-network surprise bills from anesthesiologists or assistant surgeons used to be a major problem; the No Surprises Act (effective January 2022) now provides significant protection for patients treated at in-network facilities. Still, confirming in-network status for every provider reduces the risk of an unexpected balance bill.

Request bundled pricing if your insurer offers it, or ask hospitals directly about their self-pay package rates. Bundled-payment initiatives have pushed many hospitals to offer fixed-price packages that include surgery, facility stay, implant, and rehabilitation – giving patients more cost certainty before the procedure.

Consider outpatient knee replacement at an ambulatory surgery center if your surgeon agrees you’re a good candidate. The facility savings alone can be several thousand dollars. Physical therapy costs also add up quickly across 6 to 12 weeks of sessions – verify how many sessions your insurance covers and ask your physical therapist to design a home exercise program that supplements in-clinic visits, reducing the number of paid sessions needed.

Timing your surgery strategically can also help. If you’ve already met your deductible for the year (perhaps from other medical expenses), having surgery before December 31 means you won’t need to satisfy a new deductible. Similarly, if you anticipate the surgery will push you to your out-of-pocket maximum, scheduling other needed medical care (imaging, specialist visits, procedures) later in the same calendar year can let you take advantage of having reached that cap. And under the No Surprises Act, if you’re uninsured or self-paying, you are entitled to a written Good Faith Estimate before scheduled surgery – request it and use it to compare facilities.

Consider Conservative Options First

Before committing to surgery and its cost, remember that guidelines generally recommend trying non-surgical treatment first for knee osteoarthritis. Weight management, physical therapy, activity modification, anti-inflammatory medications, bracing, and in some cases injections can meaningfully reduce pain and delay or avoid surgery for some people. Beyond the health benefits of a stepwise approach, insurers usually require documentation of these conservative measures before they will authorize a replacement. Talk with your clinician about whether you have exhausted reasonable non-surgical options – this is a medical decision, and the goal is the right treatment at the right time, not simply the cheapest one.

Frequently Asked Questions

How much does knee replacement cost with Medicare in 2026?

Under Original Medicare in 2026, you’ll generally pay the Part A hospital deductible of $1,736 per benefit period if you’re admitted as an inpatient, or the $283 Part B deductible plus 20% coinsurance for outpatient surgery. With a Medigap supplement (such as Plan G), your out-of-pocket cost can be minimal. Medicare Advantage plans have their own copays and an annual out-of-pocket maximum, so costs vary by plan. These are the official 2026 figures as published; confirm current amounts at Medicare.gov.

Is robotic knee replacement more expensive?

Robotic-assisted knee replacement typically costs roughly $2,000 to $5,000 more than conventional surgery due to the technology, equipment, and additional operating-room time involved. Studies indexed by the National Library of Medicine show improved implant alignment and positioning with robotic assistance, but long-term outcome differences compared with conventional techniques are still being studied. Most insurance plans cover robotic-assisted surgery at the same rate as conventional surgery, meaning the extra cost is often absorbed by the facility rather than the patient.

How long is the hospital stay for knee replacement?

Hospital stays for knee replacement have shortened significantly over the past decade. Many patients now stay 1 to 2 nights or go home the same day, down from 3 to 5 nights a decade ago. A substantial and growing share of eligible patients have same-day (outpatient) knee replacement and go home with home physical therapy. Shorter stays reduce the facility cost component – each additional day can add roughly $2,000 to $5,000 to the bill.

Can I negotiate the price of knee replacement surgery?

Yes, particularly if you’re uninsured or have a high-deductible plan. Hospitals routinely offer self-pay discounts for uninsured patients who ask. Request the hospital’s financial-assistance policy and ask about bundled pricing and a written Good Faith Estimate. If you’re insured, you can still manage costs by choosing lower-cost in-network facilities, asking about outpatient options, and verifying that all providers are in-network before the surgery date.

Will insurance cover knee replacement?

In most cases, yes – knee replacement is considered medically necessary rather than elective, and Medicare and commercial insurers cover it once conservative treatment has failed and imaging confirms significant joint damage. You’ll typically need prior authorization. Coverage does not mean the surgery is free: you’re still responsible for your deductible, coinsurance, and any amounts up to your out-of-pocket maximum.

Implant Choices and Their Cost Impact

The prosthetic implant itself accounts for roughly $3,000 to $12,000 of the total cost, and implant selection can influence both price and long-term outcomes. Standard implants from major manufacturers (such as Stryker, Zimmer Biomet, Smith+Nephew, and DePuy) use well-studied cobalt-chromium alloy and polyethylene bearing surfaces – these are reliable and relatively cost-effective, often $3,000 to $6,000.

Custom-made implants, designed using CT or MRI imaging of your specific knee anatomy, cost more (often $8,000 to $12,000) and may offer a better fit for patients with unusual anatomy. The evidence on whether custom implants produce meaningfully better outcomes than well-fitted standard implants is still emerging. Some manufacturers also offer gender-specific implants designed around anatomical differences, at modest added cost. Discuss implant options with your surgeon, keeping in mind that the surgeon’s experience with a particular implant system often matters more than the implant’s brand or marketing claims.

The Bottom Line

Knee replacement surgery is a major expense – roughly $30,000 to $50,000 without insurance as of early 2026 – but most patients with coverage pay significantly less, often $3,000 to $9,000 out of pocket after reaching their deductible or out-of-pocket maximum. The keys to managing cost are choosing an in-network facility (ideally one with bundled or transparent package pricing), verifying every provider is in-network, exploring outpatient surgery-center options if you’re a good candidate, and requesting a written Good Faith Estimate up front. Don’t let cost alone delay a surgery that can dramatically improve your mobility and quality of life – but do invest the time to compare options and understand your financial exposure before scheduling.
