Summary

Post-market prospective, multi-center longitudinal study to determine if mobile application-guided education and exercise paired with accurate and sensitive activity monitoring, captured from consumer wearables, can provide a viable (and potentially improved) alternative to current standard of care physical therapy for hip and knee arthroplasty.

Detailed description

This is a post-market prospective, multi-center longitudinal study in subjects undergoing primary total knee arthroplasty (TKA), total hip arthroplasty (THA), or partial knee arthroplasty (PKA). The study objective is to determine if mobile application-guided education and exercise paired with accurate and sensitive activity monitoring, captured from consumer wearables, can provide a viable (and potentially improved) alternative to current standard of care patient education and physical therapy for hip and knee arthroplasty. The study will be conducted in phases. The first phase (N = 300) will consist of a pilot cohort of subjects and will primarily serve to determine site study staffing needs and time required for various elements of study execution. The second phase (N = 1,000, RCT) will consist of a randomized controlled subject cohort and will compare outcomes of mobile application-guided exercises and activity with standard of care (SOC) physical therapy. The third phase (N \~ 10,000 including subjects from both Phase I and the study arm from RCT/Phase II) will seek to collect enough data to enable the creation of decision support algorithms for outcomes of joint replacement. All subjects will undergo a TKA, THA, or PKA using SOC procedures and commercially-available devices as part of their clinical care. Subjects will then complete prescribed post-operative activities, such as physical therapy, according to SOC or performing exercises as scheduled through the mymobility app. In office assessments will be conducted at approximately 30 days prior to surgery, 30 days after surgery, and 3 months after surgery. Virtual assessments (including subject questionnaires and recording of adverse events) will occur at approximately 6 months and 1 year post-op. February 2022 update: Eligibility criteria for new patients includes total knee and partial knee arthroplasty surgeries. Previously enrolled total hip arthroplasty patients will remain in the study for follow-up.

Interventions

Type	Name	Description
OTHER	mymobility with Apple Watch	The mymobility mobile application is a mobile software platform designed to facilitate remote episode of care management and asynchronous communication between the provider care team and their patient via provider-approved care plans and engagement communications. Current care pathways have been developed for: Total Hip Replacement, Total Knee Replacement and Partial Knee Replacement. Designed for the orthopedic population, mymobility also integrates wearable data from the Apple Watch into provider dashboards, providing enhanced understanding and monitoring of patients throughout the episode of care.
