Brief 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.

Primary Outcome Measures
NameTimeMethod
Phase II (RCT): Readmission Rate30 Days postop

RCT Phase: Non-inferiority of the mymobility with Apple Watch group in the number of readmissions through 30 days post-op compared to subjects receiving standard physical therapy.

Secondary Outcome Measures
NameTimeMethod
Phase II RCT: Healthcare Costs90 Days

The number of hospital readmissions, reoperations, urgent care visits, and emergency room visits will be captured and used to calculate the cost of care after the joint replacement procedure.

Phase II RCT: Knee Injury and Osteoarthritis Outcome Score - Joint Replacement (KOOS, JR)90 Days

The KOOS, JR score ranges from 0 to 100 where 0 represents total knee disability and 100 represents perfect knee health.

Phase II RCT: EQ-5D-5L90 Days

Non-inferiority in post-operative EQ-5D-5L outcomes for the mymobility with Apple Watch group compared to subjects receiving standard physical therapy.

Phase II RCT: Incidence of Manipulation under Anesthesia (MUA)90 Days

Comparison of incidence of Manipulation under anesthesia (MUA) between the study groups.

Phase II RCT: Hip disability and Osteoarthritis Outcome Score - Joint Replacement (HOOS, JR)90 Days

The HOOS, JR score ranges from 0 to 100 where 0 represents total hip disability and 100 represents perfect hip health.

Phase II RCT: Single-Leg Stance (SLS) Test90 Days

Balance Test while standing on a single leg. Three tests are performed and the best of the three times is recorded. The maximum time for this test is 60 seconds.

Phase II RCT: Subject Satisfaction90 Days

Comparison of subject satisfaction survey results between the study groups.

Phase II RCT: Timed Up and Go (TUG)90 Days

Timed Up and Go Test: The time to rise from a chair, walk 10 feet, turn around, walk back to the chair and sit down.
