Robotic Knee Replacement: What To Expect, Cost, Recovery, & Results

Are you experiencing chronic knee pain and/or reduced mobility due to osteoarthritis, rheumatoid arthritis, or severe injury? Your doctor may recommend robotic knee replacement surgery (also called Mako robotic knee replacement surgery). This cutting-edge procedure uses advanced technology to assist surgeons to perform more precise and accurate joint replacements. But what can you expect about the procedure, cost, recovery, and results? Here are the answers to the most frequently asked questions about robotic knee replacement surgery.

1. What Is Robotic Knee Replacement Surgery?

Robotic knee replacement surgery uses advanced robotic technology to assist surgeons in performing knee replacement procedures with enhanced precision. The robotic system aids in planning and executing the surgery, leading to potentially better patient outcomes.

During the surgery, the technology creates a 3D model of the patient’s knee, allowing the surgeon to plan and execute the procedure with precision. The robot helps guide the surgeon’s movements during the operation, ensuring that the implant is placed in the optimal position for improved joint function. “We utilize the robot to make the surgery more accurate, more precise, and more routine,” explains Dr. Lucas Romine, an orthopedic surgeon at North Carolina Specialty Hospital.

2. Who Can Benefit From Robotic Knee Replacement?

If you’re a candidate for a knee replacement because you’re suffering from severe knee pain and limited mobility due to osteoarthritis, rheumatoid arthritis, knee injuries, or deformities, you’re also a good candidate for Mako robotic knee replacement.

3. Is Robotic Knee Replacement Better Than Traditional Knee Replacement Surgery?

Robotic knee replacement boasts several advantages over traditional methods. Many studies have shown that robot-assisted surgery can result in better patient outcomes than traditional knee replacement surgery. The precision and accuracy of the system can lead to a more custom-fit implant, a reduced risk of complications, and faster recovery times, as Dr. Romine explains in the video. Additionally, patients may experience less pain and a quicker return to normal activities with a robotic knee replacement. However, both methods aim to alleviate knee pain and improve patient mobility. The best approach depends on individual patient circumstances and surgeon expertise.

4. What Are the Benefits of Robotic Knee Replacement?

Benefits include:

• Improved accuracy and precision in implant placement
• Reduced risk of complications
• Faster recovery times
• Less pain after surgery
• Improved joint function and a more natural-feeling joint
• Smaller incisions and less trauma to the surrounding muscles and ligaments

All in all, “It’s a win for patients, (and) it’s a win for surgeons. It’s a win-win,” Dr. Romine says.

5. What Is Recovery After Mako Robotic Knee Replacement Surgery Like?

In general, recovery tends to be faster than traditional surgery. Patients can expect to stay in a hospital for one to three days following surgery. Physical therapy will be an important part of recovery, helping patients regain strength, mobility, and function in their new knee joint. Patients may be prescribed pain medication to manage any discomfort. Most patients can resume most activities six weeks after surgery, but while 90% recover after three months, it can take six months or longer to achieve 100% recovery.

6. How Much Knee Flexibility Will You Get After Robotic Knee Replacement Surgery?

Typically, after a successful robotic knee replacement, patients can expect to regain significant knee flexibility. Most patients achieve a range of motion from 0 to 120 degrees, which is sufficient for most daily activities like walking, climbing stairs, and even some recreation. The goal is to restore the knee’s functionality to a level that allows patients to perform their usual activities with minimal restriction.

7. What Is the Success Rate of a Robotic Knee Replacement?

The success rate of robotic knee replacement surgery is generally high, with lower complication rates in the first three months post-surgery: 1.5% versus 2.6% from traditional knee replacement surgeries.

8. What Are the Disadvantages of Robotic Knee Replacement?

While this surgery is generally considered safe, as with any surgical procedure, there are potential risks and complications of which to be aware, including infection, blood clots, nerve damage, implant failure, and stiffness in the joint. Patients should discuss these risks with their surgeon before undergoing surgery.

9. How Long Does a Robotic Knee Replacement Last?

Robotic knee replacement implants are designed to be long-lasting, with many patients experiencing pain relief and improved function for up to 20 years. However, this can vary depending on the patient’s age, activity level, weight, and overall health.

10. How Much Does a Knee Replacement Cost?

The cost of a knee replacement can vary significantly based on several factors, including geographical location, the specific hospital or surgical center, and the healthcare provider performing the surgery. The cost for robotic knee replacement surgery typically averages more than $32,000.

11. Does Medicare Cover Robotic Knee Replacement? What About Other Insurance?

As of the latest guidelines, Medicare does cover robotic knee replacement surgery. However, coverage can depend on the specific details of the patient’s Medicare plan and whether the surgery is deemed medically necessary. It’s important for patients to consult with their healthcare provider and insurance company to understand the extent of coverage and any out-of-pocket expenses they may incur.

For those who are not on Medicare, insurance coverage can vary depending on the individual’s insurance plan. Many insurance companies generally cover this procedure, especially if a healthcare provider deems it medically necessary. Prior authorization may be required; patients should check with their insurance provider for their specific coverage details.

12. What Are the Real-World Outcomes of Robotic Knee Replacement?

Outcomes and outlooks of robotic knee replacement are generally positive, with many patients enjoying improved knee function and a return to a better quality of life. Studies indicate that robotic-assisted surgeries can lead to lower rates of implant (joint) failure when compared to traditional methods.
