The Cost of a Knee Replacement (With and Without Insurance)
Knee replacement is one of the most common surgical procedures in the United States — over 700,000 performed each year. It's also one of the most expensive. Here's what it actually costs and how your coverage can mean the difference between financial disruption and financial stability.
Total knee replacement is considered an elective procedure — meaning it's scheduled in advance rather than performed in an emergency. But "elective" doesn't mean optional. For the millions of Americans dealing with severe osteoarthritis, a knee replacement is the difference between mobility and chronic disability.
And because it's elective and scheduled, people have more time to think about the financial side. Which means they also have more time to make costly mistakes.
What a Knee Replacement Actually Costs in 2026
| Service | Estimated Cost |
|---|---|
| Surgeon fee | $10,000–$20,000 |
| Hospital/facility fee | $30,000–$50,000 |
| Implant (prosthetic knee) | $8,000–$15,000 |
| Anesthesiology | $3,000–$6,000 |
| Physical therapy (12–16 weeks) | $5,000–$10,000 |
| Total range | $56,000–$101,000 |
With Insurance vs. Without
| Without Insurance | With Good Coverage | |
|---|---|---|
| Total billed | ~$75,000 | ~$75,000 |
| Negotiated rate | None | ~$38,000 |
| Your cost | $75,000 | ~$7,500 (out-of-pocket max) |
The Timing Consideration
Because knee replacements are scheduled, timing relative to your deductible matters significantly. If you've already met your deductible earlier in the year, scheduling surgery before December 31 means insurance is covering a much higher percentage. Schedule it in January and you're starting from zero.
This is worth a conversation with your surgeon and your insurance company — not to delay necessary care, but to be intentional about when you schedule elective procedures when timing is flexible.
Also worth noting: prior authorization is almost always required for knee replacement. Your surgeon's office typically handles this, but confirm it's been submitted and approved before your surgery date. Proceeding without authorization can result in significant unexpected costs.
