Brief Summary

OBJECTIVES: Physical activity has been established as an important component of rehabilitation for knee osteoarthritis (OA), and is often guided by a physical therapist.(1) Physical therapy for knee OA typically involves 1-3 sessions with a licensed physical therapist per week, for up to 12 weeks. These sessions can take a lot of time and effort for subjects, particularly when travel times are considered. Remote patient monitoring is an emerging treatment method which can help to reduce the need for in-person treatment sessions. Remote patient monitoring has been tested in subjects after a total knee arthroplasty, and initial results show that subjects find the process motivating and engaging.(2) This process has not been tested in individuals with symptomatic knee OA. Prior studies have shown that personalized internet based programs are effective at improving function in individuals with knee OA(3), but the effectiveness of these programs with remote patient monitoring is unknown. One example of current wearable technology that can be utilized for remote patient monitoring is the Opum (OPUM) Digital Knee® (ODK) modular orthotic. The ODK utilizes a wearable device in a knee brace which relays real time information back to the subject and physical therapist via their mobile phone. The ODK can provide information about sagittal and frontal plane knee kinematics, sagittal plane knee range of motion, time spent performing various daily activities, time spent exercising, overall load on the knee joint, and progress over time in each of these metrics. This device has been previously tested in subjects after an ACL reconstruction, but has yet to be tested in subjects with knee osteoarthritis. The objective of this study is to assess the effect of the ODK technology in a medial knee unloader brace with remote patient monitoring on pain, function, and quality of life in individuals with knee OA. This study will contain two groups: A control group receiving a medial unloader brace and a personalized home exercise program, and an intervention group which will receive an ODK in a medial off-loader brace, and a home exercise program with remote patient monitoring. The hypothesis is that subjects who wear the knee brace with the ODK with remote patient monitoring will have a greater reduction in pain and increase in quality of life than those who receive the brace with a home exercise program.

Outcome Measures

Primary Outcomes (1)

  • Pain subscore on the Knee injury and Osteoarthritis Score (KOOS Survey)

    Measured by the Knee injury and osteoarthritis score subscale (KOOS subscales) as a comparison between both groups of the evolution of pain between Day 0 and Week 12.

    12 weeks from onset of brace wearing

Secondary Outcomes (14)

  • Symptoms

    12 weeks from onset of brace wearing

  • Function

    12 weeks from onset of brace wearing

  • Impact of Osteoarthritis on Quality of Life

    12 weeks from onset of brace wearing

  • Quality of life measured using the EQ5D survey

    12 weeks from onset of brace wearing

  • Walking speed

    12 weeks from onset of brace wearing

  • +9 more secondary outcomes

Study Arms (2)

Control group: Medial off-loader brace and home exercise program

ACTIVE COMPARATOR

The subject will receive a traditional medial off-loader brace and a take-home, self-guided exercise program. The subject will be instructed how to wear the brace. The subject will be instructed to incrementally increase wear time of the brace in the first week to get accustomed to the brace to reach a minimum of 6 hours per day after the first week.

Device: Knee Brace

2. Intervention group: Medial off-loader brace with OPUM Digital Knee and Remote Patient Monitoring

EXPERIMENTAL

The same off-loader brace as above but with the ODK sensor will be provided. The subject will be instructed how to wear the brace and sensor. The patient will be instructed to incrementally increase wear time in the first week to get accustomed to the brace to reach a minimum of 6 hours per day after the first week. Using the sensor they will be able to keep track of their exercise frequency, range of motion (ROM), and kinematics in the OPUM app on their mobile phone. Education/resources will also be provided to the subjects via modules in the mobile app. The subjects will be instructed how to use the app as well. Patients data will be monitored remotely for 20mins per patient per month in the sensor group. Programs will be updated as necessary based on data.

Device: Knee Brace + OPUM Digital Knee

Interventions

Knee Brace + OPUM Digital Knee

2. Intervention group: Medial off-loader brace with OPUM Digital Knee and Remote Patient Monitoring

Knee Brace without OPUM Digital Knee

Control group: Medial off-loader brace and home exercise program
