Zimmer Biomet Holdings, Inc. announced one-year data from a multicenter, prospective, randomized controlled trial to evaluate the impact of mymobility® with Apple Watch, a first-of-its-kind remote care management platform. The data show that using mymobility with Apple Watch following primary knee arthroplasty, commonly known as knee replacement, can effectively guide rehabilitation, demonstrate similar outcomes to traditional care models, and significantly reduce the number of outpatient physical therapy (PT) visits. In addition, use of mymobility with Apple Watch was associated with significantly fewer surgery-related emergency department (ED) visits, which could translate to lower costs of care*.

The data will be presented at a podium session at the 2022 annual meeting of the American Association of Hip and Knee Surgeons (AAHKS). The data presented at the 2022 AAHKS annual meeting evaluated 401 patients who underwent total or partial knee arthroplasty. Patients were randomized to a mymobility with Apple Watch exercise and educational platform group, or a control group who received traditional care.

Among the outcomes assessed at the one-year follow-up were Knee injury and Osteoarthritis Outcome Score, Joint Replacement (KOOS, JR), PT visits, readmissions, and ED/urgent care (UC) visits. Key data findings include: Patients in the mymobility with Apple Watch group who did not require adjunct PT had significantly higher KOOS, JR scores compared to controls at one year post-operatively (89.3±11.3 vs 83.8±14.6, p=0.02). Significantly fewer patients in the mymobility with Apple Watch group required post-operative physical therapy (60.6% vs.

94.6%, p<0.001). Overall KOOS, JR scores were similar between control group and mymobility with Apple Watch group at one year (83.8±14.6 vs 84.1 ±14.0, p=0.88). The change in KOOS, JR scores from pre-operative levels were similar at one year for the control group and the mymobility with Apple Watch group (32.1±17.4 vs 31.5±17.1 points, p=0.51).

Significantly fewer patients in the mymobility with Apple Watch group utilized surgery-related ED/UC care compared to the control group (1.3% vs 5.4%, p=0.03). Similar rates of readmission were observed between the mymobility with Apple Watch group and the control group (3.8% vs 2.1%, p=0.36).
