The Claim
Tibial cartilage compressive strain during walking in vivo exhibits creep behavior, characterized by asymptotic strain increase over time and stabilization after 40–60 minutes, a phenomenon previously documented only in laboratory settings and not previously observed in living humans during natural activity.
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.
When people walk, the cartilage in their shin bone gradually deforms more over time and stops increasing after 40 to 60 minutes, a pattern previously seen only in lab tests and never before measured in living humans during normal walking.
See the scientific wording
Tibial cartilage compressive strain during walking exhibits creep behavior in vivo, with strain increasing asymptotically over time and stabilizing after 40–60 minutes, a phenomenon previously documented only in laboratory settings and never before observed in living humans during natural activity.
When you walk, the weight on your knee pushes down on the cartilage, squeezing out fluid inside it. At first, fluid rushes out quickly, making the cartilage get thinner fast. Over time, the fluid keeps moving slowly through the cartilage until it spreads out evenly and stops moving. Once the fluid stops moving, the cartilage stops getting thinner, even if you keep walking.
What the research says
1 studyStudy: A New Stress Test for Knee Joint Cartilage
When people walk for a long time, their knee cartilage slowly gets squished more and more until it stops getting squished after about an hour — and this has never been seen in a living person before, until now.
