Orthopedic Surgeon Q&A: No, the Robot Doesn’t Take Over During Surgery

Experts of Avera Orthopedics use the latest technology and procedures to relieve ongoing knee, hip or shoulder pain. Joint replacement surgery is often supported by 3-D software and robotic-arm technology to help plan and perform surgery.

Travis Liddell, MD, orthopedic surgeon and Clinical Vice President of Avera’s Orthopedic Service Line, answers questions about 3-D and robotic technology.

Why is 3-D technology helpful for orthopedic surgery?

The technology builds a 3-D model of the joint, helping us choose the right size of implant and plan the implant’s position within the joint. We virtually plan the surgery and maneuver around any bone deformity or defect before the patient comes in for the actual procedure. 

What is the purpose of the robotic arm?

The robotic arm is a precise cutting tool the surgeon manually operates during surgery.

What are the potential benefits to the patient?

Robotic technology aids in the patient’s journey by personalizing their treatment plan, enhancing the surgery-planning process, cutting smaller and more precise incisions, and reducing recovery times.

However, there’s no replacement for a skilled surgeon. A good surgeon supported by the newest technology will potentially lead to the best outcome possible.

How often do orthopedic surgeons use 3-D technology and robotics?

Many surgeons only use it on a case-by-case basis. 

Why not use it?

Robots might have an added benefit for younger and more active patients. However, an older adult with lower physical demands may have just as good an outcome with a traditional joint replacement surgery.

What would you tell a patient about robotic surgery who’s a candidate for it?

The robot is a hyper-precise instrument that makes cuts exactly where we have planned out. It’s a great tool to enhance the outcome of a patient candidate.

Does the robot take over?

No, the surgeon is still the one doing the surgery. People have a perception that I’m in a back room with a joystick. No, I’m doing the surgery, scrubbed in and in the operating room.

How do you approach a patient who is afraid?

Facing any surgery can be overwhelming, with or without robots. It’s most important to focus on expertise and experience. Here at Avera Orthopedics — with our incredible team of surgeons, surgical techs and nurses — surgery is what we’re trained to do.
