Video-based function-first knee assessment for subacute knee pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study evaluates a function-based approach to knee assessment in adults with subacute knee pain (1 week to 3 months). It compares a video-based assessment focused on history and functional tasks with an in-person assessment that includes traditional tests. Primary care clinics in Västra Götaland, Sweden recruit participants who meet eligibility criteria and have access to digital technology. Outcomes include validity and reliability of the video-based assessment versus the in-person assessment, as well as interrater agreement between modalities. The study uses Ottawa Knee Rule criteria to exclude fractures and aims to determine whether digital evaluations can provide sufficient diagnostic support to guide treatment decisions.
