Robotic-assisted knee replacement surgery is transforming orthopedic care. It offers patients a more precise and less invasive alternative to traditional procedures. Research shows that robotic-assisted surgery often leads to faster recovery, better joint function, and fewer complications.
When people ask how long does a knee operation take, the answer depends on several factors — including the patient’s condition, the type of surgery, and the surgeon’s experience. On average, robotic knee surgery takes about 1.5 to 2 hours to complete. However, the improved precision can lead to shorter recovery times and better long-term results.
Understanding these details helps patients prepare mentally and physically, especially those considering medical treatment abroad. Knowing what to expect ensures confidence and smoother recovery planning.

Robotic-assisted knee surgery has seen big changes over time. These changes come from new robotic technology. This has made orthopedic surgery more precise and less invasive for patients.
Robotic-assisted knee surgery uses robots to make knee replacements more accurate. This technology lets surgeons make a plan just for the patient’s body. This can lead to better results and quicker healing.
The growth of robotic tech in orthopedics has been slow but steady. Early systems were made to fix the problems of old surgery methods. Now, these systems are much better, with advanced imaging and navigation.
Today, robots are key in orthopedic surgery. They help surgeons do complex tasks with more accuracy and less damage.
There are many robotic systems for knee surgery, each with its own strengths. Some top ones are:
These systems have greatly improved knee surgery. They offer better results and faster healing for patients.

Robotic knee surgery has changed orthopedics a lot. It offers many procedures for different needs. We use robots to make surgeries more precise and better for patients. Let’s look at the different robotic knee surgeries and how long they take.
Robotic Total Knee Replacement (TKR) replaces the whole knee with artificial parts. Robots help make sure the implants are placed just right.
Robotic systems help make personalized surgical plans. This can lead to better results and longer-lasting implants.
Robotic Partial Knee Replacement is less invasive than TKR. Only the damaged part of the knee is replaced. Robots help surgeons remove the bad parts carefully, keeping healthy tissue.
This is good for patients with just a part of their knee damaged. It means smaller cuts, less damage to tissue, and possibly faster recovery.
Robotic Knee Revision Surgery fixes or replaces a failed artificial knee. Robots help see the old implant and bone structure accurately. This makes the revision more precise.
Revision surgeries are complex. Robots help with preoperative planning and intraoperative execution. This can lead to better results in these tough surgeries.
| Procedure | Typical Duration | Key Benefits |
| Robotic Total Knee Replacement | 60-90 minutes | Personalized implant placement, potentially better outcomes |
| Robotic Partial Knee Replacement | 45-75 minutes | Less invasive, quicker recovery, preserves healthy tissue |
| Robotic Knee Revision Surgery | 90-120 minutes | Enhanced precision in complex cases, improved preoperative planning |
Many people wonder how long knee surgery takes. The time can change a lot, depending on if it’s traditional or robotic-assisted. We want to help you know what to expect.
Traditional knee replacement surgery usually lasts 1 to 2 hours. But, it can change based on how complex the case is and the surgeon’s skill. On average, a total knee replacement surgery takes about 1.5 hours. Things like the patient’s body, any extra challenges, and how well the team works together also matter.
Robotic-assisted knee surgery might take a bit longer because of the setup needed for the robot. On average, robotic-assisted total knee replacement surgery can take around 1.5 to 2 hours as well. Even though it might seem similar, robotic surgery can be more precise and might have fewer problems.
Different knee surgeries take different amounts of time. Here’s a quick look:
| Procedure | Traditional Surgery Time | Robotic-Assisted Surgery Time |
| Total Knee Replacement | 1-2 hours | 1.5-2 hours |
| Partial Knee Replacement | 1-1.5 hours | 1-2 hours |
| Knee Revision Surgery | 2-3 hours | 2-3.5 hours |
Keep in mind, these are just rough estimates. The actual time can change. The surgeon’s experience with robots and the specific system used can affect it. It’s best to talk to your surgeon for a better idea of how long your surgery will be.
Getting ready for robotic knee surgery is key to its success. We take several important steps to make sure the surgery goes well. These steps help us get the best results and avoid any problems.
Before we start, patient preparation and positioning are very important. We make sure the patient is comfortable and in the right spot on the table. This lets us easily reach the knee.
We use supports and straps to keep the leg in place. This helps the robotic system work accurately.
Robotic system setup and calibration are key steps before surgery. Our team carefully sets up the robotic system. They make sure all parts are working right.
Setting up the robotic system needs a lot of attention to detail. We follow a set process to make sure it’s ready.
Pre-operative imaging and planning are very important for robotic knee surgery. We use special imaging to make a detailed 3D model of the knee. This model helps us plan the surgery, including where to put implants.
| Imaging Technique | Purpose | Benefits |
| CT Scan | Create 3D model of knee | Accurate planning and implant placement |
| MRI | Assess soft tissue and cartilage | Comprehensive understanding of knee condition |
| X-ray | Evaluate bone structure | Identify any bone density issues |
By using these imaging methods, we can make a detailed plan for the surgery. This helps us get the best results for the patient.
Knowing the timeline of robotic knee surgery is key for both patients and doctors. It covers several important steps.
The first step is giving anesthesia. This is a mix of regional and general anesthesia. It keeps the patient comfortable and safe during the surgery.
Regional anesthesia numbs the lower legs. General anesthesia makes sure the patient is asleep.
Next, the team does surgical mapping and robot registration. They make a 3D model of the knee using advanced imaging.
The robotic system is then matched to the patient’s knee. This allows for precise surgery.
The real surgery starts here. The surgeon uses the robot for precise bone cuts and implant placement. This stage is very important for good results.
After the surgery, the team closes the incision and starts post-op care. They use sutures or staples and apply dressings.
Then, patients are watched in the recovery room. This is to check for any immediate problems and see how they’re doing.
| Stage | Description | Approximate Time |
| Anesthesia Administration | Preparation for surgery through anesthesia | 15-30 minutes |
| Surgical Mapping and Robot Registration | Creating a 3D model and registering the robotic system | 20-40 minutes |
| Active Surgical Time with Robotic Assistance | Performing the knee surgery with robotic aid | 45-90 minutes |
| Closure and Immediate Post-Op Procedures | Closing the incision and initial recovery monitoring | 15-30 minutes |
Knee surgery time varies a lot. It depends on many important things. Each case is different.
Things about the patient can change how long surgery takes. These include:
The surgeon’s skill with robotic tools is key. More experienced surgeons can do surgeries faster. This can make the whole process shorter.
The type of knee problem also matters. More complicated issues need longer surgeries.
The robotic system used can affect surgery time too. Each system has its own level of complexity and efficiency. For example:
| Robotic System | Average Surgery Time | Key Features |
| MAKO | 60-90 minutes | High precision, personalized surgical plans |
| ROSA | 75-120 minutes | Advanced navigation, real-time data |
| NAVIO | 60-100 minutes | Streamlined workflow, intuitive interface |
In summary, many things affect how long knee surgery takes. These include the patient’s health, the surgeon’s skill, the problem’s complexity, and the robotic system used. Knowing these can help set realistic expectations for the surgery.
Robotic-assisted total knee replacement surgery has changed orthopedics. It offers patients a more precise and potentially faster surgery. Understanding the benefits and duration of robotic TKR is key.
Traditional total knee replacement surgery takes 60 to 90 minutes. This depends on the case’s complexity and the surgeon’s experience. Robotic-assisted TKR might take 90 to 120 minutes. This is because of the time needed for robotic setup and calibration.
Even though robotic TKR takes a bit longer, it often leads to better outcomes. It can mean shorter recovery times. The precision of robotic systems can lead to more accurate bone cuts and implant placement.
Studies have looked into robotic-assisted TKR’s duration and outcomes. A study in a Journal found better implant positioning with robotic TKR. Another study in a Journal reported less postoperative pain and faster recovery with robotic TKR.
Clinical statistics show robotic TKR can reduce complication rates and improve patient satisfaction. As more data comes in, the benefits of robotic assistance in TKR are clear.
The surgeon’s learning curve affects robotic TKR duration. As surgeons get more experience, the operation time decreases. Initially, the setup and calibration of the robotic system add time. But, as surgeons become more familiar, they can perform the surgery more efficiently.
Research shows that after 20-50 cases, surgeons can reduce operation time. They can do this while keeping the benefits of robotic assistance. This learning curve is important when looking at robotic TKR’s efficiency.
Robotic partial knee surgery is a big step forward in orthopedic care. It’s more precise and less invasive than old methods. This makes it popular for its quick operation times and fast healing.
Unicompartmental knee replacement fixes only the damaged part of the knee. Using robots helps make the surgery more accurate. This can make the surgery shorter, often under 90 minutes.
Bicompartmental knee replacement covers two parts of the knee. It’s more complex than unicompartmental, but robots help a lot. The surgery usually takes 90 to 120 minutes with robotic help.
Robotic partial knee surgery is less invasive. Smaller incisions mean less damage and quicker surgeries. This can save 15 to 30 minutes compared to old methods.
This leads to less blood loss, less pain, and faster healing for patients.
To show how different knee surgeries compare, here’s a table:
| Procedure Type | Traditional Surgery Duration | Robotic-Assisted Surgery Duration |
| Unicompartmental Knee Replacement | 90-120 minutes | 60-90 minutes |
| Bicompartmental Knee Replacement | 120-150 minutes | 90-120 minutes |
In summary, robotic partial knee surgery is better for shorter operations and quicker healing. Robots help surgeons work more efficiently. This leads to better results for patients.

Right after robotic knee surgery, patients are watched closely in the operating room. They check vital signs, pain, and the patient’s overall health. Good care after surgery is vital for a smooth recovery.
When the patient is stable and the anesthesia is wearing off, they move to the recovery unit. How long this takes depends on the patient and the surgery. Quick transfers are important for timely care.
Robotic surgery can lead to early movement. It causes less damage and is less invasive. Starting to move early can lead to better results and fewer complications.
A good recovery plan is essential. It includes physical therapy and getting up and moving. This helps patients get strong and mobile after robotic knee surgery.
Knowing how long you’ll stay in the hospital after robotic knee surgery is key. This surgery has come a long way, making recovery faster. It might even mean you can go home sooner.
More and more, people are going home the same day after robotic knee surgery. They can leave the hospital on the day of surgery if they meet certain conditions. Whether you can go home right away depends on your health, the surgery’s complexity, and your home care setup.
If you’re healthy, don’t have too much pain, and have someone to help at home, you might go home the same day. Talking to your doctor about this is very important to know what to expect.
Not everyone can leave the hospital the same day. Some need to stay longer because of surgery complications, pain, or trouble moving. People with other health issues or living alone might also need to stay longer for extra care.
Several things can affect how long you’ll stay in the hospital after robotic knee surgery. These include:
Knowing these factors helps both you and your doctor plan better for your recovery.
