Study Details

Brief summary:

The main goal of this study is to see if there is a connection between the social and economic resources available in a patient's neighborhood (measured by the Area Deprivation Index, ADI) and their recovery after knee replacement surgery, as tracked through remote monitoring. A secondary goal is to find out if patients' self-reported pain and function score are linked to their actual physical improvement after surgery as measured by a remote therapeutic monitoring (RTM) device. Additionally, this study examines whether RTM can reduce the number of postoperative clinic visits within the first 90 days after surgery while maintaining patient satisfaction and patient-reported outcome measures (PROMs).

Interventions and Outcome Measures

Arms

experimental: Smart Knee Implant

This group will receive the smart knee implant during their arthroplasty and will be able to track their progress according to the smart metrics through a mobile application, and will otherwise have the same standard-of-care as the other arm.

no intervention: Standard-of-Care Knee Arthroplasty

This arm includes patients who are receiving the standard-of-care knee arthroplasty and will have standard follow-up with their surgeons.

Interventions

Smart Knee Implant

An important advancement in objective recovery data occurred when the first ever 'smart' knee implant for remote therapeutic monitoring (RTM) after total knee arthroplasty (TKA) was released in 2021. The implant includes both a prosthesis for TKA and a stem, the latter of which records the following metrics: step count, distance traveled, tibial range-of-motion (ROM), functional ROM, average walking speed, stride length, and cadence. The implant sends the recordings to a mobile platform. Additionally, it collects and analyzes patient across the entire population of users and creates percentiles for each metric based on patient age, gender and time since surgery. These "recovery curves" provide more objective data for practitioners and patients to evaluate recovery progress and make adjustments to their care plans accordingly.

Primary outcome measure

  • Patient-Reported Outcomes and Satisfaction [ Time Frame: From enrollment to 1 year after arthroplasty ]
