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)
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).
