Why can bone injuries heal much more rapidly than injuries to cartilage?

Rich blood supply

Blood
Because of the lack of blood supply to cartilage, (a new technique to hasten healing of injuries is to introduce fresh blood flow into the area) whereas the marrow in bones actually produce red blood cells, and bones are actually a honeycomb like structure, and they are constantly being taken apart, and rebuilt, microscopic bit by bit

Dr. Vivek Agrawal answered:

Why is it that bone injuries heal faster than cartilage injury?

Cell Growth

Bones
Cartilage cells, especially the articular cartilage type, are very slow growing cells so they are also very easily damaged and with enough damage these cells die and are replaced with a type of scar tissue that is not a perfect replacement. Bone on the other hand continues to remodel and can ultimately be fully restored.

Which of these two tissue types do you think would heal faster following an injury? (a) cartilage or bone?

Always cartilage

The stages of healing bone fractures are: Blood clots are organized by chondroblast cells into cartilage. Then invading osteoblasts convert the cartilage in bone structure; which is constantly being remodeled by both osteoclast & osteoblast cells & influenced by blood flow & stress loads. Yet many genetic, epigenetic & physiologic controls remain poorly understood.

Regeneration

Bones
The answer is simple: Your bone can regenerate whereas cartilage cannot. Once the cartilage is gone, it is gone. It can only be replaced by a live transplant.

Is it true that eating more cartilage (not in Sharks) helps bone and joint health?

Glucosamine

Bone
Glucosamine and Chondroitin, two components of cartilage, are commonly used as supplements to help with bone and joint health. Although it has received a lot of popular acclaim, there has been little rigorous testing to see if it is effective. At best, it seems to be not harmful and might be helpful. WebMD has a pretty good article on the topic. http://tinyurl.com/HTUjoint

Dr. Oscar Novick answered:

How do I know if I damaged bones such as (lesser alar cartilage) nose, other body parts? What are the clues? Will it heals to 100 percent on its own?

Damaged bones

Bones
A fractured nose may have a distorted shape, breathing through the nose may be difficult, nose may be bloody.complete healing is doubtful
