There is a common misconception that exercise may harm osteoarthritic knee joints. This leads to decreased activity levels due to fear and avoidance, which in turn will have negative effects on knee joint health.
There is consistent evidence proving otherwise, concluding that physical activity (walking, running and recreational sports) is not associated with the structural progression of knee osteoarthritis. Weight-bearing exercises are vital in delivering nutrition to the joint surfaces (articular cartilage) and integral to reducing pain.
We should also consider other risk factors for knee osteoarthritis when recommending physical activity. Obesity and previous knee injuries are the main drivers behind the progression of the condition, so ensuring a supervised physical activity program from physiotherapists or exercise physiologists become an important intervention to ensure safe progressions and gradual increase in activity levels to prevent flare-ups.
Below are some facts about knee osteoarthritis that are important to keep in mind:
- Rest and avoidance make the pain worse
- Graded exercise is safe and helpful in slowing the progression of osteoarthritis
- Pain does not equate to damage, but is more so a reflection of the sensitivity of the knee.
