Influence of Self‐Reported Knee Instability on Outcomes Following Education and Exercise: A Cohort Study of 2,466 Patients With Knee Osteoarthritis

Knee OA patients with self-reported instability seem to benefit even more from a patient education and supervised exercise therapy program than OA patients without instability.
Study context
- Population
- Patients with knee osteoarthritis (OA) in the GLA:D program (8-week education and supervised neuromuscular exercise), Denmark
- Participants
- 2,466 patients
- Exposure
- Self-reported knee instability categories vs no instability
- Outcome
- Change in knee pain intensity (0-100 mm) and gait speed (4 × 10 m fast-paced walk test)
- Follow-up
- After the program
Methodological detailslinear regression, adjusted for sex, age, BMI, physical activity level and previous knee surgery
- Linear regression
- Adjusted for sex, age, BMI, physical activity level and previous knee surgery
Main finding
Change in knee pain (0-100 mm)
Larger improvement in pain
4.3 mm
95% CI 1.2–7.5
