Robotic Knee Replacement
Arthritis & Orthopedic Medical Clinic - San Jose, Los Gatos, CA



Dr. Sagoo offers robotic-assisted knee replacement surgery, a procedure that combines proven, cutting-edge technology with the expertise of an experienced orthopedic surgeon. Robotic-assisted knee replacement surgery is effective and efficient, improving the precision of a surgeon’s work without adding extra time to surgery. This technique helps ensure successful outcomes and gets patients back on their feet as soon as possible.

Dr. Sagoo’s philosophy is to always use the least-invasive treatments first, working through a series of conservative approaches to keep patients active and pain-free. When you meet Dr. Sagoo, he will help you explore the nonsurgical tools that are available to you first. Depending on each individual and their needs, that could include anything from losing weight and taking Tylenol to undergoing physical therapy or receiving cortisol injections. If those do not help, he will talk to you about whether surgery might make sense for you. Dr. Sagoo believes surgery is not the only answer when it comes to helping patients get back to their desired lifestyle.

When surgery is the best option, Dr. Sagoo and his team utilize the latest technological improvements and advances in medicine to get optimal results for his patients. When a patient decides to undergo surgery, Dr. Sagoo uses the Mako Robotic-Arm Assisted Technology in order to give patients the best chance at a full recovery.

Common Questions on Robotic Knee Replacement

What is robotic knee-replacement surgery?

Robotic knee replacement is a procedure in which your surgeon uses advanced scanning and robotic technology to provide more-personalized surgery for the best possible results. First, software is used to help plan the surgery specifically for your anatomy and your needs. Then in the operating room, your surgeon uses a robotic arm to help remove diseased bone and cartilage, preparing your knee for the implant while protecting the soft tissue around it.

Is robotic knee surgery safe?

Yes, it’s completely safe. The robot itself does not perform the surgery, nor does it make any decisions on its own. The robotic arm is simply a tool the surgeon uses to make the most precise movements possible.

Is robotic knee replacement better?

Yes, studies have shown that using the robot arm for assistance can lead to better results. With any knee surgery, the goal is to give patients a well-balanced knee—one that’s not too loose or too tight. When a knee is well-balanced, patients do better with physical therapy and recovery, and they are happier with the results. With traditional surgery, surgeons use bone guides, which might be 1 or 2 degrees off. Sometimes those small degrees can make a difference. Using robotic assistance improves accuracy and helps achieve that balance. The Mako system used by Dr. Sagoo also gives him immediate feedback on how well-balanced the knee is at the end of the surgery, so he knows better what to expect right away.

How does the Mako Robotic-Arm Assisted Technology work?

The Mako technology helps surgeons personalize surgery for individual patients by creating a 3-D model of the knee before they go into surgery. This 3-D model is used to plan the surgery ahead of time and, along with a robotic arm that’s controlled by the surgeon, assists them in the operating room while they prepare your knee for a new implant.

Who is a good candidate for robotic knee replacement?

Anyone who has knee arthritis and who is still being held back by knee pain after going through more-conservative pain management could be a candidate for surgery. If a patient has gone through physical therapy, tried anti-inflammatory medications, and had knee injections, but pain is still affecting their everyday activities, it might be time to talk about surgery as an option.

What is the process for knee-replacement surgery?

First, a patient will come in for a CAT scan one or two weeks prior to surgery. Those results get programmed into the robotic system to help the doctor prepare for surgery. Knee-replacement surgery can be inpatient or outpatient, depending on an individual patient’s needs and circumstances. Patients are up and walking the same day, and physical therapy starts immediately, continuing until patients are back to normal activity.

What is recovery like after robotic knee surgery?

Dr. Sagoo gets his patients up on their feet within a few hours of surgery. Most people are able to go home the same day, while some might require a short hospital stay. In order to get people back to their former levels of activity, Dr. Sagoo recommends starting physical therapy right away. Most people use a walker for one to two weeks, then a cane for three to four weeks. After that, most people are able to walk without any type of assistive device. The amount of physical therapy needed depends on each patient and their goals, but it can range up to three or four months.

Is robotic knee replacement covered by insurance?

In most cases, yes, it is covered by insurance. And Dr. Sagoo and his team are in the process of making this procedure available to even more patients.
