How Much Does a Knee Replacement Cost in 2026? Complete Price Guide

Knee replacement is one of the most common elective surgeries in America — over 800,000 performed annually. It's also one of the most aggressively priced procedures in the healthcare system. The same total knee replacement can cost $15,000 at a freestanding ambulatory surgery center and $70,000 at the hospital across town. The implant is the same. The surgeon may be the same. The price difference is entirely a function of where you choose to have it done.

Knee Replacement Costs by Facility Type (2026)

The biggest lever in knee replacement pricing isn't your surgeon, your implant brand, or even your insurance — it's whether you have surgery at a hospital or an ambulatory surgery center (ASC). Here's how prices stack up:

Procedure / Setting	Cash Price (Low)	Cash Price (Typical)	Hospital Price
Total Knee Replacement (Unilateral) — ASC	$15,000	$22,000	—
Total Knee Replacement (Unilateral) — Hospital	$25,000	$42,000	$70,000+
Partial (Unicompartmental) Knee Replacement	$12,000	$20,000	$45,000
Bilateral Knee Replacement (both knees)	$27,000	$45,000	$110,000+
Robotic-Assisted Knee Replacement	+$2,000	+$5,000	+$10,000
Revision Knee Replacement (re-do)	$30,000	$55,000	$90,000+

What's Actually Included in the Price?

Knee replacement billing is notoriously complex. A quoted "all-in" price may or may not include:

Cost Component	Typical Range	Usually Bundled?
Facility fee (OR, recovery room, nursing)	$8,000–$40,000	Yes — largest component
Implant (prosthetic knee system)	$3,500–$12,000	Usually included
Surgeon fee	$2,000–$8,000	Often billed separately
Anesthesia	$1,000–$3,500	Almost always separate
Pre-op labs & imaging	$200–$1,500	Separate
Physical therapy (post-op)	$1,500–$4,000	Always separate
Inpatient hospital stay (if admitted)	$3,000–$8,000/night	Separate if inpatient

Always ask: "Does this price include the surgeon fee, anesthesia, and implant?" A $22,000 all-inclusive ASC price can be a better deal than a $35,000 hospital facility quote that doesn't include the other $10,000 in separate bills.

Knee Replacement With vs. Without Insurance

Insurance covers knee replacement when it's medically necessary — meaning you've typically exhausted conservative treatment (physical therapy, cortisone injections, bracing) and your orthopedist documents significant functional impairment. Here's how the math works:

If you have a high-deductible health plan (HDHP)

With a typical $3,000–$6,000 deductible, you'll pay that in full before insurance kicks in. After meeting your deductible, you'll usually owe 20% coinsurance until you hit your out-of-pocket maximum ($7,000–$9,000 for most plans). For a knee replacement, hitting your annual out-of-pocket max is common — meaning your maximum exposure is your deductible + OOP max, typically $7,000–$12,000.

If you have a traditional PPO or HMO

Your insurer negotiates rates with in-network facilities. For knee replacement, negotiated hospital rates are $25,000–$50,000. After your deductible and coinsurance, you'll typically owe $2,000–$8,000 out of pocket. However: if the cheapest in-network option is a hospital-owned facility, an out-of-network ASC with a bundled cash price may still come out ahead financially.

If you're uninsured or using cash pay

Your leverage is real. Ambulatory surgery centers actively court self-pay patients and frequently offer bundled prices that are 30–50% below posted rates. Some surgery centers partner with medical financing companies and offer payment plans at 0% interest. Always ask for the bundled self-pay price before accepting any quoted rate.

Hospital vs. Ambulatory Surgery Center

This is the single most impactful decision you'll make. Here's the comparison:

Factor	Hospital	Ambulatory Surgery Center (ASC)
Typical Price Range	$25,000–$70,000	$15,000–$27,000
Overnight Stay	Often required (adds cost)	Outpatient — home same day
Facility Fee	Yes — adds $15,000–$30,000	Lower facility overhead
Infection Risk	Higher (hospital-acquired infections)	Lower for elective cases
Scheduling Speed	Weeks to months	Often faster scheduling
Best For	High-risk patients, complex revision cases	Healthy patients, primary TKR

For healthy patients (no major cardiac, pulmonary, or obesity comorbidities), orthopedic ASCs deliver equivalent outcomes at dramatically lower cost. A 2023 study in the Journal of Arthroplasty found no statistically significant difference in 90-day complication rates between ASC and hospital knee replacements in low-risk patients.

What Affects Knee Replacement Pricing?

• Facility type — The biggest driver. Hospitals have overhead, facility fees, and institutional pricing that ASCs don't.
• Implant brand and technology — Standard implants cost $3,500–$6,000. Premium brands (Stryker, Zimmer Biomet) with custom or high-flex options can run $8,000–$12,000.
• Robotic assistance — Robot-assisted systems (Mako, VELYS) add $2,000–$10,000 to facility cost. Clinical benefit is procedure-specific — discuss with your surgeon.
• Unilateral vs. bilateral — Doing both knees at once saves on some facility costs but roughly doubles the price overall.
• Primary vs. revision — Revision surgery (replacing a failed or worn implant) is significantly more complex and expensive than a primary replacement.
• Geographic location — Surgery centers in the South and Midwest typically price 20–40% lower than comparable facilities in coastal metros.
• Surgeon experience and reputation — High-volume surgeons may command a premium but often have lower complication rates, potentially reducing total cost.
• Anesthesia type — Spinal anesthesia (common for knee replacement) is generally less expensive than general anesthesia and associated with faster recovery.

How to Find the Best Knee Replacement Price

1. Ask for a bundled case rate

Many ASCs and some hospitals will quote a bundled price that includes facility fee, implant, and surgeon fee in one number. This is the cleanest way to compare apples to apples. Call scheduling at each facility you're considering and ask: "Do you offer a bundled cash price for total knee replacement?"

2. Verify your surgeon is the same across facilities

Many orthopedic surgeons operate at both hospital and ASC settings. Your preferred surgeon may be available at a significantly cheaper ASC — you just need to ask. The surgical team is often the same; only the building changes.

3. Use price transparency data

Since 2021, hospitals are legally required to publish machine-readable pricing files. careprices.ai aggregates this data from 6,500+ facilities and 5 billion+ pricing data points so you can compare real prices before you commit to a facility.

4. Time your surgery strategically

If you have insurance with an annual deductible reset, having surgery early in the year (after meeting a prior-year deductible) or late in the year (when you may have already met your current deductible) can significantly reduce out-of-pocket costs. Elective knee replacement is rarely urgent — timing is worth planning.

5. Negotiate the implant cost separately

Savvy patients sometimes work directly with their surgeon to select a standard implant at a lower implant cost, then apply savings toward other components. Some facilities will quote implant costs separately if asked. A standard implant from a major manufacturer is clinically equivalent to premium options for most patients.

Does Medicare Cover Knee Replacement?

Yes. Medicare Part A covers inpatient knee replacement (hospital stay), and Medicare Part B covers outpatient knee replacement at an ASC or hospital outpatient department. For 2026, the standard breakdown:

• Part A (inpatient): $1,676 deductible for days 1–60 of hospital stay. If you're admitted overnight, this applies.
• Part B (outpatient/ASC): 20% coinsurance after the annual $240 deductible. On a $20,000 ASC case, your Part B share would be roughly $4,000 — but Medigap plans often cover this entirely.
• Medicare Advantage (Part C): Varies by plan. Many Advantage plans have zero cost-sharing for knee replacement at preferred facilities.

If you're on Medicare and considering knee replacement, the ASC vs. hospital distinction still matters — outpatient ASC rates are typically lower, which directly reduces your 20% coinsurance share.

What to Expect From the Surgery and Recovery

• Surgery duration: 1–2 hours for a primary unilateral knee replacement
• Anesthesia: Typically spinal or general; epidural nerve blocks increasingly common for post-op pain management
• Hospital/facility stay: Outpatient ASC — home same day (most cases). Hospital — 1–3 nights if inpatient
• Weight-bearing: Walking with assistance the same day or next morning is now standard protocol
• Physical therapy: Begins immediately post-op; 6–12 weeks of formal PT is typical
• Return to daily activities: 4–6 weeks for most activities; 3–6 months for full recovery
• Implant longevity: Modern implants last 15–20+ years in most patients
• Success rate: Over 90% of patients report significant pain reduction and improved function at 1 year

The Bottom Line

Knee replacement is expensive regardless of where you go — but the spread between the cheapest and most expensive option is enormous. A $50,000 price gap exists for the same surgery in the same city. Most patients don't discover this because their surgeon's office schedules them at the affiliated hospital by default. Breaking that default and asking about ASC options — with your same surgeon — is the highest-leverage financial decision you'll make in this process.

Use price transparency tools, ask for bundled quotes, and remember: the facility fee, not the surgeon or implant, is what makes knee replacement expensive at hospitals. Remove the facility fee by choosing an ASC and you remove the largest cost driver in one decision.
