Understanding Knee Replacement Surgery
When considering the cost of knee replacement surgery, it's vital to first understand what the procedure entails and the different types available. This understanding can help you better weigh your options and make an informed decision.
What is Knee Replacement Surgery?
Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure that replaces a worn-out or damaged knee with an artificial joint, or implant. The goal of this surgery is to relieve pain and restore function in severely diseased knee joints. Most often, the procedure is necessary when other treatments such as physical therapy or medications fail to alleviate pain or improve mobility.
Most total knee replacements at HSS are performed under regional anesthesia called an epidural block, providing numbness from the waist down and eliminating pain during surgery. Patients are also given a light sedative to make them as sleepy or awake as they want to be.
The procedure generally takes about 60 to 90 minutes, but patients should expect to be in the operating room for over two hours. Following surgery, rehabilitation begins within 24 hours, with patients starting with gentle exercises to improve range of motion and prevent circulation problems. Rehabilitation is key to the success of the surgery and recovery.
Types of Knee Replacement Surgery
There are two primary types of knee replacement surgeries:
- Total Knee Replacement (TKR): This is the most common form. In this procedure, the damaged parts of the thighbone (femur) and shinbone (tibia) are removed and replaced with an implant made of metal and plastic components. Knee replacement implants are expected to function for at least 15 to 20 years in 85% to 90% of patients. However, the implants do not last forever and may require revision surgery after a period of wear and tear.
- Partial Knee Replacement (PKR): This procedure is an option for patients whose arthritis is limited to just one part of the knee. Because only a part of the knee joint is replaced, this procedure has a shorter recovery time compared to total knee replacement.
In both cases, within two or three days after surgery, a patient will be able to start walking with assistance from a straight cane, walker or crutches. The distance and frequency of walking will increase as the days progress, but complete recuperation and return to full strength and mobility may take four months or more.
Understanding these procedures, their potential outcomes, and recovery times can be crucial when considering 'how much does knee replacement surgery cost.' It's important to discuss these options with your orthopedic surgeon to determine the best course of action for your specific needs.
Cost Factors in Knee Replacement Surgery
When contemplating knee replacement surgery, understanding the cost involved is crucial. Several factors contribute to the overall cost of the procedure, including location and hospital charges, and whether the surgery is inpatient or outpatient.
Location and Hospital Charges
The cost of knee replacement surgery can vary significantly depending on the geographical location and the specific hospital where the operation is performed. According to a study by Blue Cross Blue Shield, the average cost of a knee replacement procedure was $31,124, but costs varied from as low as $11,317 in Montgomery, Alabama, to as high as $69,654 in New York, New York. In Dallas, Texas, the cost could range from $16,772 to $61,585, indicating a 267 percent cost variation based on the hospital.
| Location |
Cost Range |
| Montgomery, Alabama |
$11,317 |
| New York, New York |
$69,654 |
| Dallas, Texas |
$16,772 - $61,585 |
These disparities highlight the importance of considering location and hospital charges when planning for knee replacement surgery. It is also crucial to note that these costs may not include other related expenses, such as pre- and post-operative care and equipment, which can further impact the overall cost.
Inpatient vs Outpatient Surgery
The type of surgery, whether inpatient or outpatient, also significantly affects the cost of a knee replacement. In 2019, Blue Cross Blue Shield estimated that the average cost of an inpatient knee replacement procedure was $30,249, while outpatient knee replacements cost $19,002. The primary reason for this cost difference is that outpatient surgeries typically require a shorter hospital stay, averaging 2.3 days compared to 3.4 days for an inpatient procedure.
| Surgery Type |
Average Cost |
Average Hospital Stay |
| Inpatient |
$30,249 |
3.4 days |
| Outpatient |
$19,002 |
2.3 days |
These figures underscore the importance of discussing with your surgeon and insurance provider to understand the financial implications of both inpatient and outpatient procedures. By doing so, you can make an informed decision about the best option for your health and your budget.
Insurance and Knee Replacement Surgery
Insight into the influence of insurance on the cost of knee replacement surgery is crucial when considering this medical procedure. The role of insurance in covering the costs of such surgeries will vary depending on the type of insurance, be it Medicare or private insurance.
Medicare Coverage
Medicare insurance can significantly help offset the cost of knee replacement surgery. Medicare Part A covers costs for inpatient surgery, including a brief stay in a skilled nursing facility post-surgery. After meeting the Part B deductible, Medicare Part B may cover 80% of the charges for outpatient surgery and also the evaluation, follow-up, and physical therapy sessions.
Medicare typically covers 100% of inpatient charges related to a knee replacement surgery and hospital stay once the deductible is met [2].
Private Insurance Coverage
Private health insurance coverage plays a significant role in determining the out-of-pocket costs for knee replacement surgery. Most insurance brands, including HealthPartners, along with Medicare and Medicaid, cover knee replacements, with varying costs depending on specific plans, copays, deductibles, or coinsurance [1].
In contrast to Medicare, private insurance plans pre-negotiate fees with hospitals and providers and usually only pay a percentage of the total charges [2]. It's essential to understand your coverage, including copays, deductibles, and coinsurance, before proceeding with the surgery [1].
In conclusion, understanding your health insurance coverage can play a crucial role in managing the financial implications of knee replacement surgery. Always verify with your insurance company the extent of the coverage before proceeding with the procedure to avoid unexpected costs. It's also advised to compare various insurance plans and choose the one that offers the most coverage and benefits for knee replacement procedures.
Additional Expenses in Knee Replacement Surgery
When calculating the overall costs of knee replacement surgery, it's crucial to consider extra expenses that are not included in the core surgical procedure. These can encompass pre- and post-operative care, as well as costs related to equipment and potential home modifications.
Pre- and Post-Operative Care
In addition to the surgery itself, patients must also account for the costs of preoperative tests and postoperative care. Preoperative tests may include blood tests, EKGs, and imaging scans, while postoperative care often entails physical therapy and routine follow-up visits. According to Healthline, outpatient charges typically account for services not provided while in the hospital, such as these pre- and post-operative services.
While Medicare typically covers 80 percent of these outpatient service charges, coverage by private insurance plans can vary significantly. Therefore, it's important for patients to understand their insurance plan's specific coverage and potential out-of-pocket costs, which could reach into the hundreds or thousands of dollars.
Equipment and Home Modification Costs
Knee replacement surgery often requires the use of special equipment for successful recovery. This can include durable medical equipment such as a continuous passive motion machine, walker, or crutches. Home care services, physical therapy, and potential home modifications for accessibility may also be necessary.
As Healthline explains, these additional costs can vary based on the specific needs of the patient and the coverage provided by their insurance plan. Out-of-pocket expenses can be significant and should be factored into the overall budget for the surgery.
In conclusion, understanding the full financial scope of knee replacement surgery involves considering all potential costs, not just the surgery itself. By taking into account pre- and post-operative care costs, as well as expenses related to equipment and home modifications, patients can better plan for the financial aspects of their knee replacement journey.
International Knee Replacement Surgery
In the journey to regain mobility and improve quality of life, some individuals choose to explore options beyond their local healthcare systems. International knee replacement surgery is one such option, often chosen for potential cost savings. However, it's essential to consider all factors involved in this decision.
Cost Savings and Considerations
One of the main reasons why people opt for knee replacement surgery overseas is the potential for cost savings. In countries like Mexico, India, or Taiwan, the initial cost for such procedures can be significantly lower than in the United States. However, it's important to remember that the total cost of surgery isn’t just the procedure itself.
When considering the financial aspects of international knee replacement surgery, several extra expenses come into play. These include costs for airline tickets, accommodation, meals, and other related travel expenses. It's also essential to consider the potential costs for any follow-up care or unexpected medical complications that may arise post-surgery [3].

Choosing an Accredited Facility
While cost is a crucial factor, it should never be at the expense of quality and safety. When selecting a facility for knee replacement surgery abroad, one critical aspect to consider is whether the hospital or clinic has received international accreditation.
Accreditation by bodies such as the Joint Commission International (JCI) is a good indicator of high standards of care. This accreditation ensures that the facility meets rigorous performance standards and is committed to providing safe and efficient patient care.
In summary, while international knee replacement surgery can offer cost savings, it's crucial to factor in all potential expenses and ensure the chosen facility adheres to high medical standards. This balanced approach can help individuals make an informed decision about how much their knee replacement surgery might cost, where it should take place, and what they can expect in terms of care and results.
Outcomes and Efficiency in Knee Replacement
The cost of knee replacement surgery is certainly a key consideration, but it's equally important to consider the outcomes and efficiency of the procedure. This section will delve into the role of surgeon and hospital volume in patient outcomes and discuss potential post-operative complications and recovery scenarios.
Surgeon and Hospital Volume
The experience of the surgeon and the volume of surgeries carried out at a particular hospital can significantly impact the outcome of knee replacement surgery. Geographical variation is associated with better outcomes for surgical procedures in private and high-volume hospitals, as well as operations performed by more experienced surgeons with a higher volume of operations per year [4].
| Factors Associated with Better Outcomes |
| Private Hospitals |
| High-Volume Hospitals |
| Experienced Surgeons |
Lower bed-day costs were associated with private hospitals and treatment centers, high-volume lead surgeons and hospitals, and patients with better pre-operative health scores. This illustrates the potential for cost savings and improved outcomes when operations are conducted by experienced professionals in well-equipped facilities.
Post-Operative Complications and Recovery
Post-operative recovery is a crucial aspect of the knee replacement process. Factors associated with a longer length of stay (LOS) for patients undergoing primary total knee replacement (TKR) surgery include older age, higher ASA grade, and higher Charlson Comorbidity Index (CCI) score.
| Factors Associated with Longer LOS |
| Older Age |
| Higher ASA Grade |
| Higher CCI Score |
Moreover, the probability of developing complications in the 6 months after surgery was associated with older age, higher CCI score, higher ASA grade, lower-volume hospitals, and public hospitals [4].
| Factors Associated with Post-Operative Complications |
| Older Age |
| Higher CCI Score |
| Higher ASA Grade |
| Lower-Volume Hospitals |
| Public Hospitals |
The mean length of stay (LOS) for total knee replacement in England varied across health areas, ranging from 2.7 to 6.6 days [4].
The effectiveness of knee replacement surgery and the speed of recovery are dependent on a variety of factors, including the patient's overall health, the expertise of the medical team, and the facilities available at the hospital. Therefore, when estimating the cost of knee replacement surgery, one must also consider these factors, as they can significantly influence the overall value and success of the procedure.
