Is the cartilage still dead? If the cartilage has not yet died, consequently cauliflower ear has not yet formed, there is the possibility of cartilage fenestration, in which the surgeon cuts a small window in the auricle. Thereupon, the accumulated blood can drain through this small opening.
How does the dead bone tear out of the joint capsule?
When the dead bone then detaches from the healthy environment under load, the cartilage cover also tears: the piece of bone detaches from the joint surface together with the overlying cartilage and forms a foreign body in the joint capsule ("joint mouse" or "dissekat").
Is the cartilage not able to generate its own healing?
Conversely, however, the cartilage is not able to generate its own healing in the event of damage due to the lack of blood supply. Cartilage damage can occur as a result of accidents, incorrect loading or old age.
Why is cartilage damage responsible?
The cartilage damage is responsible for this. This state of irritation or inflammation has a negative influence on the other parts of the joint (mucosa, ligaments, bones) and fundamentally increases the risk of developing osteoarthritis (Fig. 4) in the course of time.
What needs to be repaired in cartilage damage? In the case of pure cartilage damage (Fig. 6: arthroscopic image of cartilage damage in the knee joint with underlying healthy bone), only the cartilage thus needs to be repaired. In the case of cartilage-bone damage, both the bone and the cartilage must be replaced.
Who is most commonly affected by cartilage damage?
Hyaline cartilages are most commonly affected by cartilage damage. Hyaline cartilages are the most common cartilage tissue in the body. On the one hand, they cover the joint surfaces and are responsible for smooth gliding.
Which types of cartilage are most commonly affected? Doctors distinguish between 3 types of cartilage: hyaline cartilage, elastic cartilage and fibrocartilage. Hyaline cartilages are most frequently affected by cartilage damage. Hyaline cartilages are the most common cartilage tissue in the body.
What is a joint capsule?
The joint capsule is the connective tissue covering of a joint. As a continuation of the periosteum, it forms a kind of tube that surrounds the joint on all sides. It consists of an outer fibrous layer (membrana fibrosa) and an inner layer (membrana synovialis).
How does a joint capsule work for acute joint pain?
Even though joint capsule tests testify that taking capsules for acute joint pain has a positive effect, the lasting effect for more mobility and cartilage formation has not been proven. The rapid effect is due to the active ingredient methylsulfonylmethane (MSM for short), which has an analgesic effect and inhibits inflammation.
How does the inner layer of the joint capsule change?
The inner layer of the joint capsule (the membrana synovialis) reacts to the injury with an inflammatory reaction, synovitis. The composition and the amount of synovial fluid change considerably ( see also: Synovial fluid: pathological changes ).
Is the cartilage no longer present?
As soon as the cartilage in the knees is no longer present, the joint surfaces rub against each other and pain results. Healthy cartilage, on the other hand, can distribute the pressure and serves as a buffer, imposing a lighter load on the bones.
Why is the problem with cartilage damage in the knee? Because the problem with cartilage damage in the knee is that these structures cannot heal on their own. They lack not only the supply from a nerve, but also from blood vessels, which are very important for the healing process.
What is the adjacent tissue in cartilage damage? The adjacent tissue, which reacts when the cartilage of the knee is damaged, is partly responsible for this. Acute pain occurs when the piece of cartilage has completely detached. If the cartilage tissue is already severely worn or no longer present, the body can no longer build up this protective mass on its own.
Can I really operate on my cartilage damage?
At the latest when the cartilage is injured by trauma and severe cartilage damage has occurred, the patient becomes aware of this enormous importance. Because he must learn from his doctor, the cartilage damage does not heal on its own. Do I really have to operate on my cartilage damage? Yes or No?
What is improvement of cartilage damage to body joints?
Improvement of cartilage damage to body joints are. Cartilage tissue (hyaline cartilage in the narrower sense) does not heal on its own after damage. An existing defect remains or expands over time as a result of further mechanical stress.
How does the relief of the cartilage happen? This happens when the cartilage is squeezed out like a sponge during stress - and when the stress is relieved, nutrient-rich synovial fluid is absorbed into the cartilage. Regular alternation between loading and unloading as well as an adequate supply of nutrients that are active for the joint thus promote the maintenance of healthy cartilage.
Is the newly formed cartilage susceptible to degenerative changes?
However, the newly formed cartilage is less resilient and susceptible to degenerative changes and is therefore only a poor substitute. Currently (2017), the treatment of cartilage damage is the subject of intensive research efforts.
What vitamins are important for cartilage?
Vitamin C is involved in the formation of collagen, the basic substance of cartilage. It thus makes an important contribution to the normal function of cartilage and bone. In addition, vitamin C is the most important water-soluble antioxidant in the body.
Is there evidence of a tear at the joint capsule?
It is relatively difficult to detect a capsular tear by visual diagnosis or anamnesis. Even if patients describe typical symptoms during the patient interview and bruising such as swelling on the finger, foot or knee indicates a damaged joint, this does not yet prove a tear in the joint capsule.
What is an inner lining of the joint capsule? Inner lining of the outer joint capsule, consisting of several layers of synovial fluid. This membrane serves as a lubricant and nutrient supplier for surrounding joints. If a tear of the joint capsule occurs, it is due to a displacement (dislocation) of joint sections.
What is the main function of the joint capsule? The joint capsule also has as one of its main tasks to provide protection for the respective joint. It completely encloses the joint as a protective mantle. Without the joint capsule, our joints would have significantly less stability.
How are the joint capsules affected?
In the case of injuries, therefore, the joint capsule is always affected first, before damage occurs to the actual joint. The joint capsule also seals the respective joint so that the joint fluid does not leak out. The joint capsules in our body consist of two layers: Membrana fibrosum and Membrana synoviale (synovial membrane).
What is capsule tear at the joint capsule?
This is damage to the connective tissue at the joint capsule. A capsule tear can be recognized by swelling, pulsating pain and a bruise may also develop.
