SAN DIEGO — In a presentation at the American Academy of Orthopaedic Surgeons Annual Meeting, Fred D. Cushner, MD, FAAOS, discussed the use of a novel stem with an embedded sensor to remotely monitor patients after total knee arthroplasty.
Researchers implanted a single, anatomically designed knee system with a customized tibial stem extension (Persona IQ, Zimmer Biomet) containing 3D accelerometers, 3D gyroscopes, a power source and a telemetry transmission capability in six cadaver specimens. Results showed good quality in transmission of sensor data, as well as good correlation in range of motion.
“This is remote patient monitoring at its best. While you can use wearables, they have problems in regard to compliance,” Cushner, of Hospital for Special Surgery, said. “Once this is in, this could get up to 20 years of data on the knee replacements. We’re excited about it and we’re excited about what the future holds with this type of device.”
