Quantitative Assessment of Walking (Squawk) With the Canary canturioTM te (CTE) Tibial Extension

Recruiting
Conditions
Arthritis Knee
Interventions
Other: Clinical Limping Evalution
Registration Number
NCT05693818
Lead Sponsor
Canary Medical
Brief Summary

The objective of this prospective study is to demonstrate accuracy of a limp detection model using a healthcare provider assessment as the non-reference standard.

Detailed Description

The primary endpoint of the study is limp severity at the 4-6 week office visit. At 4-6 weeks (+/- 3 days) post-surgery, the healthcare team will assess the patient's limp severity by visual observation on a 3-point Likert scale (0=No limp, 1=Mild/Moderate or 2=Severe).

Primary Outcome Measures
NameTimeMethod
Limp Severity4-6 wks+3 days weeks post TKA

The primary endpoint of the study is limp severity at the 4-6 week office visit. At 4-6 weeks (+/- 3 days) post-surgery, the healthcare team will assess the patient's limp severity by visual observation on a 3-point Likert scale (0=No limp, 1=Mild/Moderate or 2=Severe).

Secondary Outcome Measures

ROM will be measured by a goniometer

Positive Percent Agreement (PPA)

Limping Self Evaluation4-6 wks+3 days weeks post TKA

Study participants will be asked the following question, "During the past week, have you been limping when walking, because of your knee?" The following answers will be allowed:

* Rarely / never

* Sometimes or just at first, after sitting for a long time

* Often, not just at first

* Most of the time

* All of the time
