Use of the DJO Brace With the Motion Intelligence Platform in the Postoperative Total Knee Arthroplasty Patient

Northwell Health16 enrolled

Overview

This is a single center, investigator initiated clinical trial using a FDA approved, marketed brace called DJO X4. This phase 4, prospective, randomized clinical trial is being conducted to evaluate the use of the X4 knee brace with the Motion Intelligence platform in patients having unilateral TKA. The study is designed to determine if using a "virtual rehabilitation" device leads to enhanced recovery following TKA by improving patient objective and subjective outcome measures.

This is a prospective, randomized clinical trial to evaluate the use of the X4 knee brace with the Motion Intelligence platform in patients having unilateral TKA. This brace is a FDA approved, marketed product being used as per the manufacturer's (DJO) marketed indications. This study is designed to determine if using a "virtual rehabilitation" device leads to enhanced recovery following total knee arthroplasty by improving patient objective and subjective outcome measures. These outcomes will be collected using a validated tool called the Knee Society Score (KSS). The KSS is a standard of care tool collected for all TKA patients pre-operatively and postoperatively at the 8 week visit. Patients will be randomized to one to 4 cohorts: DJO X4 Brace with Motion Intelligence Platform: Home discharge-Home. Patients randomized to this group will be provided with the X4 brace and trained on the use of Motion Intelligence platform. Control group-Home discharge. Patients randomized to this group will serve as the control group. There will be no changes to the standard of care recovery for a TKA patient. DJO X4 Brace with Motion Intelligence Platform: Discharge to rehabilitation center. Patients randomized to this group will be provided with the X4 brace and trained on the use of Motion Intelligence platform. Cohort 4- Control group: Discharge to rehabilitation center. Patients randomized to this group will serve as the control group. There will be no changes to the standard of care recovery for a TKA patient. The DJO X4 brace will be provided to the patient at no cost. Study visits, hospitalization, inpatient and outpatient rehabilitation costs are standard of care and will be the responsibility of the patient. There will be no payment for participation in this study. All study patients will complete a daily "Daily Patient Log" starting the day after discharge from the hospital until postoperative day (POD) 56. This log will document the patient's location: * Rehabilitation center or * Home physical therapy or * Physical therapy center * Hospital (re-admission) * Return to work (if applicable) The study hypotheses is that the X4 brace with the Motion Intelligence platform will provide an enhanced, cost-effective postoperative recovery following total knee arthroplasty (TKA).

Interventions

DJO X4 brace with Motion Intelligence PlatformDEVICE

The X4 Knee brace with the Motion Intelligence platform uses both a bio-measurement equipment with an interactive application thereby providing the patient with immediate feedback on their exercise regime. The X4 Knee brace is a postoperative brace worn by a patient to monitor compliance to prescribed protocol based on the movement and function of the knee joint. The device also connects wirelessly to a companion mobile application, Motion Intelligence, and streams both real-time and collected data for review and record collection. Prescribed exercises are uploaded into the patient application, with a number of the exercises actively tracked by the Mi360 sensor housed in the X4 brace. Compliance can be tracked by the physician in real-time between postoperative visits and any medical staff on a separate dashboard.

Outcomes

Primary Outcomes

Change in the Calculated "Knee Society Score"

Functional outcomes measured by the 2011 "Knee Society Score". The Functional Activities section consists of 4 sub-sections with a total score ranging from 0-100 points. The higher the numerical value the better the outcome. The sub-sections consist of: (1)Walking and Standing 0-30 points (2)Standard Activities 0-30 points (3)Advanced Activities 0-25 points (4)Discretionary Knee Activities 0-15 points.

Time frame: Preoperatively and 8 weeks postoperatively
