How Much Does a Knee Replacement Really Cost in the US?

Introduction: Why Knee Replacement Costs Matter More Than Ever

Knee replacement surgery is one of the most common orthopedic procedures in the United States. According to the American Academy of Orthopaedic Surgeons (AAOS), over 790,000 knee replacements are performed in the U.S. each year, a number expected to grow as the population ages and more people stay active later in life.

Yet, the cost of this procedure remains a major barrier for many patients. While insurance can help, out-of-pocket expenses are still significant for most people, especially when deductibles, copays, and coinsurance are factored in.

In this post, we’ll break down what a knee replacement actually costs in the U.S., why those numbers vary so widely, and what patients can expect to pay depending on insurance status and location. While our focus here is on U.S. pricing, we’ll also preview why some Americans are exploring care options in places like Mexico, a topic we’ll explore in more detail in later posts in this series.

What Is a Knee Replacement?

Before we dive into cost, it’s important to understand what the surgery involves. A knee replacement, also called knee arthroplasty, is a procedure in which damaged or diseased parts of the knee joint are replaced with artificial components made of metal and high-grade plastics.

There are two main types:

• Total Knee Replacement (TKR) – The entire knee joint is replaced.
• Partial Knee Replacement (PKR) – Only one section of the knee joint is replaced, often when damage is limited to a specific area.

The complexity of the procedure, along with the materials used and the length of hospital stay, are all major cost drivers.

The Average Cost of Knee Replacement in the U.S.

The average cost of a total knee replacement in the U.S. ranges from $30,000 to $65,000, according to data from Healthcare Bluebook and Kaiser Family Foundation.

Partial knee replacements are typically less expensive, averaging $22,000 to $35,000, but they are less common and only suitable for certain patients.

These costs include:

• Surgeon’s fees
• Hospital or surgical facility charges
• Anesthesia
• Implants and medical devices
• Pre- and post-operative care (consultations, physical therapy)

However, these are averages the actual bill can be much higher or lower depending on several factors.

Why Costs Vary So Widely

Knee replacement pricing isn’t uniform across the country. Factors that can significantly impact the total cost include:

1. Geographic Location
Hospital costs in major cities like New York, San Francisco, and Chicago are significantly higher than in smaller metropolitan areas or rural hospitals.

• Example: New York City average: $55,000
• Example: Oklahoma City average: $25,000

2. Hospital vs. Outpatient Facility
Inpatient hospital stays add substantial cost. Some patients qualify for outpatient or same-day knee replacement, which can reduce facility charges by thousands.

3. Surgeon Experience
Highly specialized orthopedic surgeons may charge more due to their expertise, success rates, and patient demand.

4. Length of Hospital Stay
Every additional night in the hospital increases the bill. Medicare data shows that average stays are around 3 days, but complications can extend this.

The Role of Insurance in Knee Replacement Cost

If You’re Insured
Most private insurance plans and Medicare cover knee replacement surgery if it’s medically necessary. However, your out-of-pocket costs will depend on:

• Annual deductible amount
• Coinsurance percentage
• Copay for hospital stays
• Out-of-network penalties

Example:

• Surgery cost: $40,000
• Insurance covers 80% after deductible
• Patient responsibility: $8,000 (plus deductible)

If You’re Uninsured
Without insurance, patients are billed the full amount. While hospitals sometimes offer self-pay discounts, the cost is often still $25,000–$65,000 — a major financial burden.

Hidden Costs Patients Often Overlook

The surgical bill is only part of the equation. Patients should also plan for:

• Pre-operative tests (blood work, imaging): $500–$1,500
• Post-surgical medications: $100–$500
• Physical therapy: $50–$150 per session, often 2–3 sessions per week for several months
• Mobility aids: walkers, canes, knee braces ($50–$300)
• Time off work: Lost wages during recovery can add up, especially for those without short-term disability insurance.

The Financial Strain for Many Patients

The National Institute for Health Care Management found that nearly 1 in 3 insured Americans struggle to pay medical bills, even with coverage. Knee replacement, with its high price tag, can push households into debt or force them to delay care — which often leads to worse outcomes.

It’s no surprise, then, that an increasing number of patients are looking for high-quality, lower-cost options outside the U.S., including Mexico. We’ll cover that in detail in the next post.
