Knee Replacement Surgery Cost in 2026

The cost of knee replacement surgery across the United States depends on several factors, including the type of facility, whether you have insurance, and local market dynamics.

The total cost of knee replacement surgery includes more than the surgeon's fee. Facility charges, anesthesia, pre-operative testing, and post-operative care all contribute. Ambulatory surgery centers, where medically appropriate, can offer significant savings compared to hospital settings.

Based on data from 1730 hospitals across the United States, knee replacement surgery prices range from $0 to $178,088 — a 178088.3x difference. This wide variation underscores why comparing prices before scheduling is critical for controlling your out-of-pocket costs.

Knee replacement surgery across the United States can be performed in different settings depending on clinical complexity: hospital inpatient, hospital outpatient, or ambulatory surgery center (ASC).

ASCs typically offer lower prices because they have lower overhead and specialize in efficient, high-volume outpatient procedures. For eligible patients, ASCs can save 30–60% compared to hospital outpatient departments.

Not all patients are candidates for outpatient surgery. Your surgeon will determine the appropriate setting based on your health history, the procedure's complexity, and anticipated recovery needs.

Self-pay patients across the United States often have access to significantly discounted rates for knee replacement surgery. Under federal price transparency rules (45 CFR § 180.50), hospitals must publish their discounted cash prices alongside standard charges.

Across the United States, the average cash price for knee replacement surgery is $14,217, which is 39% lower than the average list price of $23,209. This discount is typical of what self-pay patients can expect when asking for the hospital's uninsured rate.

Insured patients should check their plan's Summary of Benefits and contact their insurer for a pre-authorization cost estimate. Your out-of-pocket cost depends on your deductible, copay or coinsurance, and whether the provider is in-network. Even with insurance, comparing hospitals can help you choose a provider where your plan negotiates the best rates.
