Robotic-Arm Assisted Knee Replacement in Sherman Oaks and Santa Clarita, CA
If knee arthritis is making it difficult to walk, stay active, or enjoy everyday activities, robotic-assisted knee replacement may be an option to consider. Dr. Alireza K. Nazemi, MD, MS, is a Board-Certified orthopedic surgeon orthopedic surgeon providing advanced knee care, including robotic-assisted total knee replacement, for patients in Sherman Oaks, Santa Clarita, and surrounding Southern California communities.
What is Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement surgery is an alternative to the conventional knee replacement procedure. It is performed using robotic-arm technology that allows your surgeon to precisely perform the surgery through a smaller incision as compared to traditional surgery.
What is Arthritis?
The knee is made up of the femur (thighbone), the tibia (shinbone) and the patella (kneecap). The two menisci, the soft cartilage between the femur and tibia, serve as a cushion and help absorb shock during motion. Arthritis (inflammation of the joints), injury or other diseases of the joint can damage this protective layer of cartilage, causing extreme pain and difficulty in performing daily activities. Osteoarthritis is a type of arthritis.
What is Total Knee Replacement?
Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn out or damaged surfaces of the knee joint are removed and replaced with artificial implants.
What are the Indications for Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement is indicated if you are suffering from degenerative knee diseases such as osteoarthritis. Your doctor may recommend surgery if non-surgical treatment options have failed to relieve your symptoms.
What is the Procedure for Robotic-Assisted Knee Replacement?
The goal of total knee replacement surgery is to relieve pain and restore the alignment and function of your knee. Robotic-assisted knee replacement utilizes X-rays and CT scans to determine the damaged areas of the joint that need to be removed for the precise placement of the knee implant. Then, the damaged portions of the femur bone are cut at appropriate angles using specialized jigs. The femoral component is attached to the end of the femur with or without bone cement.
Your surgeon then cuts or shaves the damaged area of the tibia (shinbone) and the cartilage. This removes the deformed part of the bone and any bony growths, as well as creates a smooth surface on which the implants can be attached. Next, the tibial component is secured to the end of the bone with bone cement or screws.
Your surgeon will place a plastic piece between the implants to provide a smooth gliding surface for movement. This plastic insert will support the body’s weight and allow the femur to move over the tibia, like the original meniscus cartilage.
The femur and tibia with the new components are then put together to form the new knee joint.
To make sure the patella (kneecap) glides smoothly over the new artificial knee, its rear surface is also prepared to receive a plastic component. All these steps are performed with the help of the robotic arms.
With all the new components in place, the knee joint is tested through its range of motion. The entire joint is then irrigated and cleaned with a sterile solution. The incision is carefully closed; drains are inserted and a sterile dressing is placed over the incision.
What are the Benefits of Robotic-Assisted Knee Replacement?
The benefits of the robotic-assisted knee replacement include:
- Smaller incisions
- Rapid recovery
- Precise placement of the implant
- Reduced injury to adjacent tissues
- Increased longevity of the implant

Robotic-Arm Assisted Knee Replacement FAQs
Who may be a candidate for robotic-arm assisted knee replacement?
Patients with advanced knee arthritis, persistent pain, and difficulty with daily activities may be candidates when nonsurgical treatments have not provided sufficient relief. A consultation helps determine whether knee replacement is appropriate.
How does robotic-arm assisted knee replacement work?
The technology helps the surgeon plan the procedure and guide bone preparation and implant positioning. The surgeon remains in control of the operation and makes decisions throughout the procedure.
Is robotic-arm assisted knee replacement better than traditional knee replacement?
Robotic assistance may help with surgical planning and precision, but it is not necessarily better for every patient. Outcomes depend on factors such as the patient's condition, implant selection, surgical technique, and rehabilitation.
Does robotic-arm assisted knee replacement use a smaller incision?
Incision size varies according to the patient's anatomy and the surgical approach. Robotic assistance does not automatically mean that every patient will have a smaller incision.
How long does recovery take after robotic-arm assisted knee replacement?
Recovery varies by patient. Many people begin standing and walking with assistance soon after surgery, followed by physical therapy. Regaining strength, mobility, and confidence can take several weeks to months.
Will I need physical therapy after knee replacement?
Yes, rehabilitation is generally an important part of recovery. Exercises help improve knee movement, build strength, and support daily function. Your care team will recommend a program based on your progress.
How long do knee replacement implants last?
Implant longevity varies depending on factors such as activity level, body weight, implant design, and overall health. Your orthopedic surgeon can explain expected durability and ways to help protect your new knee.
What are the possible risks of robotic-arm assisted knee replacement?
As with any major surgery, potential risks include infection, blood clots, bleeding, stiffness, persistent pain, nerve or blood vessel injury, and complications related to anesthesia or the implant. Your surgeon can discuss your individual risk factors.
Can both knees be replaced using robotic assistance?
Some patients may be candidates for replacement of both knees, either during one operation or in separate procedures. The safest approach depends on overall health, functional needs, and surgical assessment.
When should I consider knee replacement?
You may want to discuss knee replacement if persistent knee pain, stiffness, or limited mobility continues to affect daily life despite appropriate nonsurgical treatment. An evaluation can help clarify the available options.
Where can I consult a specialist for robotic-arm assisted knee replacement?
Dr. Alireza Nazemi sees patients in Sherman Oaks and Santa Clarita, California. A consultation can help you understand whether knee replacement and robotic assistance may be suitable for your condition.
