The Claim
Joint movement facilitates nutrient delivery and waste removal in avascular cartilage through mechanical pumping of synovial fluid.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Movement of joints drives the flow of synovial fluid, which delivers nutrients to and removes waste from cartilage tissue that lacks blood vessels.
See the scientific wording
Joint movement facilitates nutrient delivery and waste removal in avascular cartilage through mechanical pumping of synovial fluid.
When a joint moves, the cartilage gets squeezed and releases fluid, which pushes nutrient-rich fluid in and waste fluid out, keeping the cartilage alive even though it has no blood vessels.
What the research says
2 studiesWhen you move your joints, it squeezes the cartilage like a sponge, helping it soak up good stuff and push out bad stuff — even though cartilage has no blood vessels. This study showed that squeezing cartilage in the lab made it act healthier and heal better.
Study: A New Stress Test for Knee Joint Cartilage
When you walk, your knee cartilage gets slightly squished, and this squeezing helps push nutrient-rich fluid in and waste fluid out — like squeezing a sponge. The study showed cartilage gets more squished the longer and faster you walk, which means movement really does help feed and clean your knee cartilage.
