Cartilage heals slower than bone because cartilage is avascular. Meaning there is no blood vessels. The lack of blood flow creates a slow healing process.
Bone heals faster than cartilage because cartilage is avascular (no blood flow). This means that the blood flow necessary in injury repair will not get to the cartilage immediately; it will take much longer. Bone, however, does have blood flow because bone marrow produces red blood cells, which are able to repair the damage to the bone.
Cartilage has a very poor blood supply which means that nutrients to aid healing are not readily available and it therefore takes a long time to heal, if indeed it does. Bone on the other hand, has an excellent blood supply which helps remove damaged tissue and debris plus it brings a healthy supply of new cells to support rapid remodelling. A completely healed bone (provided the fracture wasn't complicated) will lead to a structure that is just as strong as it was prior to injury. Although the main building work is done by approximately 8 weeks or so, it will actually take up to two years for full strength to be returned. Proper rehabilitation will ensure that the process is optimised e.g by doing weight bearing exercise as appropriate to strengthen the bone.

∙ 15y agoCartilage in joints is avascular - it has no direct blood supply. As such, nutrients must diffuse to it through the synovial fluid (or from the perichondrium in some joints) which is slow and inefficient. The slow passage of necessary materials causes a slow healing rate.

∙ 11y agobecause articular cartilage lacks the perichondrium, a layer surronding the cartilage and responsible for the synthesis of chondroblasts. In the absence of chondroblast, chondrocytes cannot be formed by appositional growth and by interstitial growth, therefore a damaged cartilage cannot be regenerated.

∙ 12y agoCartilage and tendons are both connective tissues with very poor blood supplies and relatively few dividing cells in the mature tissue. Both of these factors contribute to the long, slow healing process. In contrast, bone (also a connective tissue) has a rich blood supply and a large proportion of active dividing cells, so bones heal relatively quickly.

∙ 9y agoThe explanation as to why cartilage heals slowly after an injury is because it contains very few blood vessels, if any at all. Cartilage is a connective tissue.

How long does it take for a kittens nose to heal after bumping into metal?
The amount of time for a kittens nose to heal after getting injured on metal will depend on the severity of the injury. Usually, if the injury was not bad, the nose should heal within a week.
How long does it take for a budgies broken leg to heal?
it depends on how bad of a break it is, and if the wing needs to be "set" if the break is too bad, it may never heal properly, even if seen by a vet.
What long term affects will a greenstick hock fracture have on a puppy?
Young animals heal more quickly than older ones, so if the fracture heals straight, the puppy should have no trouble in the future. The vet will probably put a cast on the leg so that it will heal properly. Fractures take about six weeks to heal. After that, the cast can come off and the puppy will be able to walk around normally.
How long does take a hairline fracture to heal on dogs?
Healing occurs in dogs at varying rates depending on the age of the pet, severity of the damage, and if the fracture is stabilized. For example, young puppies generally heal within a few weeks, while healing can take several months in older dogs. Be sure to limit your dog's activity during the healing process so it will not incure further injury.
What do you do with horses with bowed tendons?
You should take the horse to a vet. Be sure to wrap the leg and ice it every day with an ice pack. Take the horse for walks but do not ride it until your vet gives the say-so.

How long does it take for an industrial to heal?
Industrials can take up to 6 months to heal due to the reduced circulation in the cartilage.
How long to wait after getting your ear lobes pierced to get your cartilage pierced?
I'd wait till your lobes are completely or nearly completely healed. Cartilage piercings take longer to heal and if your body is trying to heal your lobes AND cartilage at the same time, it'll take even longer for your cartilage to heal. So, 2-3 mths.
How long does it take for conch piercings to close?
Cartilage piercings never close the surface tissue may shrink to obscure the opening but the hole in the cartilage is life long and will never heal up.
What are bones held together by?
Bones are held together by flexible and tough bands of flesh called tendons. Tendons are usually very hard to break, but if they are snapped, take a long time to heal.
How long does cartilage take to heal?
When you pierce your cartilage, it is supposed to do a good job of healing. However, there are plenty of people who find that their cartilage piercings heal in a different way - with a keloid, or bump, on the back or front of the piercing.
Cartilage heals poorly and in many instances does not heal or recover at all after a severe injury Why not?
Cartliage take over a year to heal. When I got mine done it took about a year and a half to heal. This is because your cartilage doesn't produce it's own blood. So when you get it pierced it has to wait to get blood and oxygen from the rest of the body. So this of course is why it takes such a long time to heal
How long does it take for a cartilage piercing to heal?
Six to eight weeks or longer, cartilage is the slowest of all piercing to heal due to the lack of blood circulation in that area. So you need to be patient with the piercing and keep it clean other than that it's a matter of time.
Cartilage pierced 5 weeks agothe location of it bothers me the piercer didnt put it in the helix part of my ear but rather deeper in the cartilage. If i take it out will it heal totally?
Well you can remove it and the tissue portion of the piercing will heal however the incised cartilage will not heal. Cartilage doesn't heal like other areas of the body, it will develope a lump as it attempts to close and heal and this could last for weeks to months depending on the area. As for the duration of time you have had the piercing that's what makes the healing hard to judge. See in hospitals I.V.'s are relocated after 24 to 48 hours so that the body doesn't try to heal around the I.V. cath. Any time you exceed 48 hours your body will start to heal the piercing by forming a tissue tube around the jewellery. So I would guess if you remove the jewellery and leave it out all together it may heal but it will take a considerable period of time because it's cartilage and there is not the blood circulation in that area to support a shorter healing time. That's why cartilage piercings take so long to heal in the first place. Good luck.
Will it hurt if you force yourself into the splits?
Yes. You can damage muscles and tendons which may cause pain and take a while to heal.
Why do ligaments and tendons recover slowly if injured?
Ligaments are said to be hypovascular structures, which in plain English means they do not receive much blood. The slow healing of ligaments is thought to be secondary to this characteristic. In the words of former pro football player and later actor Alex Karras: "Ligaments don't heal". That is a bit of an overstatement - but not much.
