TECH SHOWCASE: Handheld Robotics in Total Knee Arthroplasty

    Editor’s Note: A session at ICJR’s 13th Annual Winter Hip & Knee Course was billed as a Technology Showcase, featuring 8 presentations on aspects of technology and techniques intended to help surgeons improve outcomes of hip and knee arthroplasty. We are highlighting those presentations on ICJR.net this week.

    Ran Schwarzkopf, MD, MSc, predicts that advanced technologies will be the future of total knee arthroplasty (TKA) – really, all joint replacement procedures – with every surgeon having some type of advanced (or “smart”) technology available in the OR.

    What those technologies will look like, and how they will perform, won’t necessarily be the same as what’s on the market now. Instead, future technologies will evolve and adapt to meet surgeons’ needs, rather than forcing surgeons to adapt to the technology.

    One example is the camera in navigation and robotic system. It’s the most important part of these systems, Dr. Schwarzkopf said, and it should be accurate, fast, and reliable – speed, in particular, makes a big difference in the impact of the technology on the workflow.

    However, the surgeon’s line of sight can be problematic with the currently available systems. It’s presently the biggest downside of these technologies, Dr. Schwarzkopf said.

    To improve the line of sight in the future, surgeons might wear the camera on glasses during the procedure, he said. Or the camera might be placed in a stable location in the OR.

    Another option is the use of a handheld robotic device, one of which Dr. Schwarzkopf helped to design. This technology uses arrays that can move, helping to improve the surgeon’s line of sight. It’s also portable technology, which he said makes it ideal for moving from room to room in an ambulatory surgery center.
