Robotic knee replacement has changed orthopedic surgery a lot. People often wonder how long it takes. On average, it’s between 1.5 to 2.5 hours per knee.
The exact time can change. This depends on how complex the case is and the surgeon’s skill. Knowing this helps patients get ready for their surgery and know what to expect.

Knee replacement surgery has seen big changes thanks to new technology. Now, thanks to robots, surgeries are more precise and effective. This change has made surgeries better for patients.
Old knee replacement surgeries depended on the surgeon’s skill. While good, it had its limits. Robotic-assisted surgeries, though, offer better accuracy and fit for each patient. Robots help plan the surgery, making bone cuts and implant placement more precise.
Several big steps have improved knee replacement surgery. One key change is 3D imaging and virtual modeling. These tools let surgeons see the knee in detail, plan better, and try out the surgery before starting.
The table below shows the main differences between old and new knee replacement surgeries:
| Feature | Traditional Knee Replacement | Robotic-Assisted Knee Replacement |
| Precision | Limited by human error | Enhanced accuracy with robotic assistance |
| Customization | Limited personalization | Highly personalized based on patient anatomy |
| Surgical Planning | Based on X-rays and surgeon expertise | Utilizes 3D imaging and virtual modeling |
| Surgery Time Frame | Varies; typically longer due to manual adjustments | Can be more efficient with precise robotic assistance; robotic knee replacement surgery time frame is often optimized |
Robotic knee replacement surgery has changed orthopedic care a lot. It offers precision and customization that old methods can’t. The tech in robotic surgery helps surgeons plan and do the surgery with better precision. When thinking about how long is robotic knee surgery, remember it depends on the case’s complexity and the surgeon’s robotic skills.
Knowing how long robotic knee replacement surgery takes is key for both patients and doctors. It helps in planning and getting ready for the surgery. It also sets the right expectations for how long it will take to recover.
The average time in the operating room for this surgery is 1.5 to 2.5 hours per knee. This time can change based on how complex the surgery is and the doctor’s skill with robotic tech. Robotic-assisted surgery makes planning and doing the surgery more precise, which can make it faster.
In clinics, the whole surgery time, from start to finish, can be 2.5 to 3.5 hours. This time includes getting ready and closing up. It depends on the patient’s body, the robotic system used, and other factors. Good preoperative planning and advanced robotic systems can cut down the time in the operating room.
While the surgery time is important, it’s just one part of the treatment. Things like surgeon experience and the specific robotic platform used also play big roles in how well and fast the surgery goes.

The robotic knee surgery timeline has several key parts. Knowing these parts helps us understand how long the surgery takes.
The pre-surgical setup is very important. It includes getting the operating room ready, placing the patient, and checking all equipment. This can take 30 minutes to an hour, based on the case’s complexity and the team’s experience.
Key steps in pre-surgical setup include:
Calibrating the robotic system is also key. It makes sure the system matches the patient’s body perfectly. This usually takes 15-30 minutes.
The calibration process involves:
| Component | Average Time | Description |
| Pre-Surgical Setup | 30-60 minutes | Preparation of the operating room and patient |
| Robotic System Calibration | 15-30 minutes | Calibration of the robotic system to the patient’s anatomy |
| Actual Surgical Intervention | 60-90 minutes | The actual surgery performed by the surgeon using the robotic system |
The actual surgery is the main part. Here, the surgeon does the knee replacement with the robotic system. The time needed can change based on the case’s complexity, the surgeon’s skill, and the robotic system used.
A study in the Journal of Orthopaedic Surgery found the surgery lasts about 90 minutes on average. But, it can vary with each case.

In summary, the robotic knee surgery timeline includes setup, calibration, and the surgery itself. Understanding these parts helps us see how long the surgery takes and the benefits of using robots.
It’s important for patients and surgeons to know what affects the time it takes for robotic knee replacement surgery. The surgery’s length depends on several key factors.
The patient’s body and health greatly influence how long the surgery takes. Complex body structures or health issues can make the surgery longer.
For example, those with severe bone problems or past knee surgeries need more time and care. A study in the Journal of Orthopaedic Surgery showed that those with more bone loss need longer surgery times. This is because they often need more bone grafting.
| Patient Condition | Average Surgery Time |
| Standard Anatomy | 60-90 minutes |
| Complex Anatomy | 90-120 minutes |
| Previous Knee Surgeries | 120-150 minutes |
The surgeon’s skill with robotic technology also matters a lot. More experienced surgeons can do the surgery faster.
“Surgeon experience is a critical factor in the success and duration of robotic knee replacement surgery. As surgeons become more adept with the technology, they can achieve better outcomes in less time.” An Orthopedic Surgeon
The robotic system used can also affect surgery time. Each system is different in complexity and ease of use. For instance, the Mako Robotic-Arm Assisted Surgery system is known for its precision and ease, which can make the surgery faster.
The choice of robotic platform, along with the surgeon’s experience and the patient’s anatomy, affects the surgery’s efficiency and length.
In robotic knee replacement, careful planning before surgery is key. It helps make the surgery faster and better. This planning uses advanced imaging to make a detailed plan for each patient.

Using 3D imaging and virtual modeling helps surgeons plan better. They can understand the patient’s knee better. This leads to faster surgeries and better results.
Patient-specific surgical planning is a big part of pre-surgery prep. It uses 3D imaging data to make a plan just for the patient.
Having a detailed plan before surgery makes the procedure smoother. It cuts down on extra steps and lowers the chance of problems. This is very important in robotic knee surgery, where being precise is critical.
The mix of 3D imaging, virtual modeling, and patient-specific planning makes robotic knee surgery better. It makes the surgery more efficient and effective. This way, surgeons can help patients recover faster and get better results.
The robotic knee replacement procedure is a detailed process. It aims to give patients the best results. This method has changed orthopedic surgery, making it more precise and tailored to each patient.
The first step is giving anesthesia. An anesthesiologist makes sure the patient is comfortable and pain-free. The anesthesia used is often a mix of regional and general types.
After anesthesia, the surgeon makes a planned incision. The incision’s size and location depend on the patient’s body and the robotic system. Robotic technology allows for smaller cuts than traditional surgery.
Next, the robotic system is used for registration. It creates a detailed map of the knee. This map helps the surgeon make accurate cuts and adjustments.
The last step is preparing the bone for the implant and placing it. The robotic system gives feedback to the surgeon. This ensures the implants are correctly placed, which is key for the surgery’s success.
