Interventional
Description of intervention(s) / exposure
All study participants will receive client-specific education of exercise and osteoarthritis (OA) by an Accredited Exercise physiologist (AEP)/AEP student (personalised knee health information) in a short verbal exchange (10min) following baseline data collection (conducted by an AEP/AEP student). Advice will focus on engaging in 1) aerobic and resistance exercise, 2) flexibility training and 3) education about OA/crepitus, its prognosis, causes and 4) role of exercise as is standard practice for AEPs (Hinman et al., 2023). This will not be recorded.

the following outcomes will be assessed during the 1hr study visit to the University of Sydney campus Camperdown:
Knee sounds: recorded by handheld sound recording device during lower limb physical health and function outcomes (e.g. squatting).
Anthropometry and demographics: height, weight, BMI, waist circumference, age, gender, race, comorbid conditions, history of knee injury/surgery, occupation, resting blood pressure.
Questionnaires: Exercise and Sports Science pre-screening tool, Knee Injury and Osteoarthritis Outcome Score, International Physical activity questionnaire (IPAQ), Tampa Scale of Kinesiophobia, Pain self-efficacy questionnaire, Pain catastrophising scale, Patient global impression of change scale.
Qualitative: participant perceptions/interpretation of crepitus, function, pain and related exercise behaviours (short semi-structured interview).
Physical health and functional capacity: 3-repetition maximal (3-RM) strength test of knee extension, knee flexion, and leg press, timed up and go (TUG) test.
Immune cells and biomarkers: blood sampling of venous blood (10mL total) -optional (and may occur on a different day/time).
3 months after initial study visit: participant perceptions/interpretation of change in crepitus, function, pain and related exercise behaviours and perceptions of the initial AEP clinic visit (short semi-structured interview).

Summary
Brief summary
This study aims to understand whether different types of knee sounds are associated with knee issues. We also would like to understand perceptions that people have regarding their creaky knees and usefulness of an Exercise Physiology assessment session for their knee function and health. The study will ask people, with/without knee osteoarthritis, to attend a 1-hour knee assessment session at the University of Sydney. In this session knee health will be assessed, knee sounds recorded, and exercise advice provided. Three months later the participants will be interviewed about their knee health and if they found the AEP session useful.
