A 32-year-old member asked:

what is the purpose of the cartilage rings of the trachea?

Support: The cartilage rings (which aren't really rings because they don't go all the way around) give support to the trachea so it doesn't collapse during respiration and give some protection as well.

A 36-year-old member asked:

Can getting cartilage tears be a hereditary problem?

Dr. John Ayres
Orthopedic Surgery 37 years experience
No: Cartilage tears occur from being active. There is no hereditary component to it. If you come from a physically active family, your family is more likely to have activity-related injuries, like cartilage tears, . It's not because it runs in your family, it's because your family runs.

A 39-year-old member asked:

Can your meniscal cartilage heal on its own with enough time?

2 doctor answers5 doctors weighed in
Dr. Gwo-Chin Lee
Orthopedic Surgery 23 years experience
No: Meniscal tears usually do not heal because the blood supply is poor. Only peripheral tears which tend to be unstable have a potential for healing because these tears occur in a zone with good blood supply. However, because these tend to be unstable, patients have surgery because of significant knee symptoms.

Can cartilage be reshaped through manual manipulation or pressure?

No: The overall shape of the cartilage is fixed and cannot be changed. The cartilage can deform and absorb energy and shock through manipulation, but will go right back to its original shape. That is the amazing part of cartilage. Pressure and manipulation will only temporarily change its shape (it immediately returns to its normal configuration).
A 23-year-old member asked:

The area around my r 6&7 rib - the costal cartilage feels like friction or something crackling there, is it "normal "?

Cartilage and ribs: The 6-9th ribs share a common cartilagenous connection with the sternum. You may have had a cartilage separation - very painful but usually due to high force trauma. You may also have costochondritis - which is a painful inflammation of that joint. A rib x-ray should be able to give some clues.
