Emory University’s Orthopaedics & Spine Hospital is a participating facility in a new clinical study in conjunction with Zimmer Biomet Holdings, Inc.-- a global leader in musculoskeletal healthcare-- and Apple, to change the patient journey for two of the most common surgeries in the US – knee and hip replacements.


The collaboration has yielded Zimmer Biomet mymobility™, an app that uses Apple Watch, to facilitate a new level of connection between patients and their surgical care teams. This interaction can immediately impact the journey patients experience when they undergo these procedures. In addition to the app, Zimmer Biomet is commencing the mymobility Clinical Study, designed to study the app's impact on patient outcomes and overall costs for joint replacement patients.


During this research study, patients will use Zimmer Biomet mymobilityTM with Apple Watch as they progress through their hip or knee replacement journey. Researchers will combine patient-reported feedback with continuous health and activity data from Apple Watch and provide new insights into the power of the Zimmer Biomet mymobilityTM app. The goal is to impact the standard of care for these common surgeries. The study has the possibility to enroll as many as 10,000 patient participants in the United States.


"We are incredibly excited to work with Apple to transform the knee and hip replacement experience for patients and surgeons," said Bryan Hanson, President, and CEO, Zimmer Biomet. "At Zimmer Biomet, we are committed to improving care decisions through digital health and we are thrilled to launch one of the largest evidence-gathering clinical studies in orthopaedic history."


"We believe one of the best ways to empower consumers is by giving them the ability to use their health and activity information to improve their own care," said Jeff Williams, Chief Operating Officer, Apple. "We are proud to enable knee and hip replacement patients to use their own data and share it with their doctors seamlessly so that they can participate in their care and recovery in a way not previously possible through traditional in-person visits. This solution will connect consumers with their doctors continuously, before and after surgery."


More than one million knee and hip replacements occur annually in the U.S. This number is expected to grow to 3.5 million by 2035, yet standardization of care and recovery for the procedures is still lacking and costs to the U.S. health care system continue to rise.


As a participating facility, Emory, led by Thomas Bradbury, MD, will provide patients involved in the study with an Apple Watch. Using the Zimmer Biomet mymobility app, patients receive a virtual and continuous care team on their wrists. Patients will be provided with support and guidance as they prepare for and recover from these surgeries, while surgeons will be delivered continuous data to optimize care.

The new Zimmer Biomet mymobility app has several features that use both Apple Watch and iPhone through the joint replacement journey, including the ability for Bradbury to send education and therapy reminders directly to the patient's Apple Watch. The app also allows Bradbury to monitor patient activity levels throughout the days and weeks while they are preparing for and recovering from surgery.

“This innovative approach to post-operative care has the potential to tremendously impact patients’ rehabilitation and follow up experiences,” explains Bradbury. “We are excited to participate in such an important endeavor and are extremely optimistic about what this means for our patients.”
