The Truth About Osteoarthritis: Movement is Cartilage Nutrition
Busting the “Wear and Tear” Myth
An osteoarthritis diagnosis often leads people to avoid movement out of fear of worsening joint damage. However, resting too much can actually increase stiffness, pain, and weakness.
-
Dynamic Tissue: Cartilage isn't like a car tire—it thrives on controlled mechanical loading.
Natural Adaptation: Safe, regular activity signals your joint to strengthen support structures and stay resilient.
How Movement Feeds Your Cartilage
Joint cartilage lacks a direct blood supply and relies on synovial fluid for oxygen and vital nutrients. It works like a sponge:
-
Compression: Weight-bearing squeezes waste products out of the cartilage.
Decompression: Unloading pulls nutrient-rich fluid back into the joint.
Inactivity starves joint cartilage, increasing stiffness and inflammation.
Key Benefits of Targeted Movement
-
Builds Shock Absorbers: Strengthening surrounding muscles reduces joint pressure.
Improves Control: Neuromuscular training improves joint alignment during daily tasks.
Calms Pain: Regular exercise releases natural pain inhibitors and reduces swelling.
The GLA:D Program: Evidence-Based Care
Evidence-based programs like GLA:D™ (Good Life with osteoArthritis in Denmark) deliver structured, supervised movement with proven outcomes:
-
Reduced joint pain intensity and decreased reliance on painkillers
Enhanced physical function and mobility
Delayed or prevented joint replacement surgeries
