A Study of the Construct Validity of Community Walking Speed Data Collected Remotely With the Canary canturioTM te Tibial Extension

September 15, 2023 updated by: Canary Medical

A Multicenter, Single- Arm Postmarket Study of the Construct Validity of Community Walking Speed Data Collected Remotely With the Canary canturioTM te Tibial Extension

The purpose of this study is to determine the construct validity of the Canary Tibial Extension's measure of self-selected community walking speed. Construct validity will be assessed by the Pearson's correlation coefficient between self-selected community walking speed and the 4-meter walk test. The objective of this multicenter, prospective study is to demonstrate that remote measurement of community walking speed with the Canary canturioTM (CTE) tibial extension is correlated with the fast 4-meter walk test (4mWT).

Study Overview

Status

Completed

Detailed Description

The primary endpoint is community walking speed, calculated as a mean, remotely captured over the 7 days prior to the patient's regularly scheduled office visit: specifically, the correlation (Pearson correlation coefficient) of community walking speed with the 4mWT.

The secondary endpoints are as follows:

  • Correlation coefficient between community walking speed and the Timed Up and Go (TUG) Test
  • Completeness of data collection and transmission by the study device
  • Correlation coefficient between community walking speed and the Oxford Knee Score
  • Correlation coefficient between community walking speed and the Knee Injury and Osteoarthritis Outcome Score Jr (KOOS JR)

Intervention / Treatment
PIQ Patients
Patient is scheduled for or has undergone primary total knee arthroplasty (TKA) using a Persona Personalized Knee System with Canary Tibial Extension (PIQ) TKA implant according to the appropriate surgical technique and IFU. If you decide to take part in this research study, the general procedures include one follow-up visit where you will be asked to complete two performance-based tests that are used to assess your physical function following Total Knee Arthroplasty ("TKA"). As part of your standard of care, you will receive a Zimmer Persona® Personalized Knee System with Canary canturioTM (CTE) tibial extension. As part of this study, subjects will be asked to perform two performance based tests called the 4 meter walk test and the timed up and go test. Subjects will also be asked to complete a series of patient questionnaires that will assess their post-operative function.
Patients will be asked to perform a fast 4-meter walk test (4mWT) and the Timed up and Go (TUG) test in the clinic during their post-operative follow-up visit. Both performance exams will be performed in a controlled environment within the physician's clinic.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
4 Meter Walk Test
Time Frame: 4 wks+2 weeks post TKA
A 4MWT test will be performed in the physician's clinic along a clear pathway of at least 8 in length in a designated area over solid flooring. The 8-m distance will be measured with a starting (0m) and an end point (8m) with additional marks at 2m and 6m to identify the 4m which is the timed portion of the test. A handheld, calibrated stopwatch will be used as the gold standard for measuring walking speed output during the 4 mWT, measuring the time it takes to complete the test.
4 wks+2 weeks post TKA
Timed Up and Go Test *(TUG)
Time Frame: 4 wks+2 weeks post TKA

Patients may use a walking aid if needed. Patients will begin by sitting back in a standard armchair. Investigator will identify a line 3 meters (9.8 feet) away on the floor. When the investigator says "go" the patient will:

  1. stand up from the chair
  2. walk to the line on the floor at a comfortable and safe walking speed
  3. turn and walk back to the chair at a comfortable and safe walking speed
  4. Sit down again A stopwatch will be used to record the time it takes from the initiation of the exam on the word "go" to the end of the exam when the patient's buttocks touch the seat.
