About this video
Last updated: 9 October 2026
The video says early cartilage wear is subtle, but the signs are there if you know where to look. It describes cartilage, the smooth rubbery tissue that cushions a joint, as having no blood supply of its own, so it cannot heal the way muscles or ligaments do.
Key points
- The signs it lists are stiffness after sitting, swelling after a long walk, or a dull ache that takes longer to settle after activity.
- It adds that some people notice crunching or discomfort when going downhill.
- The video says that when cartilage is irritated often enough, the knee begins to compensate by shifting pressure to other areas or altering walking patterns.
- It says addressing these changes early is not about rushing into treatment, but about understanding what stage the cartilage is in.
