Anonymous users2024-02-121. What is cartilage?
Cartilage (connective tissue) is made up of cartilage tissue and surrounding perichondrium. Cartilage can be divided into hyaline cartilage, elastic cartilage, and fibrocartilage according to the nature of fibers. The cartilage in the joints of the human body is hyaline cartilage.
Articular cartilage is a vital presence. On the one hand, the synovial fluid (synovial fluid) in the articular cartilage has a lubricating effect. On the other hand, articular cartilage reduces friction between bones.
Especially in sports, it can share a part of the gravity of the joint, just like a cushion on the joint, cushioning part of the pressure.
2. What should I do if cartilage is damaged?
The importance of articular cartilage is directly proportional to its vulnerability. For young people, a little carelessness on weekdays can lead to joint cartilage damage, such as overloaded exercise. For the elderly, joint fibrosis, coupled with the reduction of joint fluid, can easily lead to damage to the articular cartilage.
It is important to note that articular cartilage does not regenerate, which means that once it is damaged, it is permanent.
Articular cartilage cannot regenerate because there is no innervation in articular cartilage and there are no blood vessels, and the nutrients it needs must be obtained from joint fluid (synovial fluid), which itself cannot secrete synovial fluid (synovial fluid).
Once there is no lubrication of joint fluid in the joints, the joints will rub against each other, which may eventually cause joint diseases such as bone spurs and osteoporosis.
We talk about joint injuries for a long time, and it is the articular cartilage that is damaged. If your joints are severely damaged and have interfered with your daily life, you can only undergo surgery**, which is the joint replacement surgery mentioned earlier.
The principle of joint replacement surgery is to remove the broken cartilage and bone and cover the surface with artificial joints to replace the original articular cartilage of the human body.
The purpose of this is to allow synovial fluid to move in and out of the articular cartilage, promote blood circulation in the lower extremities, and increase the volume of synovial fluid.

Anonymous users2024-02-11The cartilage at the joint is without blood and nervous system, and its existence depends on the nutrient solution secreted from the joint cavity, so the cartilage at the joint can not be regenerated, many patients will feel pain when the knee is damaged, in fact, when the cartilage at the joint is worn out, the patient will not feel pain, most of the knee pain is due to the tear or injury of the cartilage caused by the friction between the cartilage and the bone. Because cartilage cannot be regenerated, patients can only undergo joint replacement surgery when cartilage problems occur.

Anonymous users2024-02-08Hello friends! The cartilage of the knees cannot be regenerated, and when the organism dies (or no longer metabolizes), the carbon atoms no longer have a chance to enter the body, and the proportion of carbon-14 remains the same as on the day of death. Due to the frequent nuclear test explosions in the past 100 years, the proportion of carbon-14 in the atmosphere has been accurately recorded, and we can easily compare the time when a piece of biological tissue stopped metabolizing.
Cartilage tissue is a connective tissue that has no blood vessels and a low metabolic rate, making it difficult to repair. It is mainly composed of chondrocytes and a large number of extracellular matrix secreted by them.
The main component of the extracellular interstitium is collagen, which is formed by three long chains of amino acids that are coiled with each other, which has excellent anti-tensile properties and is the main component of cartilage, tendons, and ligaments. Glycosaminoglycan is a polysaccharide with hygroscopic and anti-compressive properties, and the commonly heard chondroitin and hyaluronic acid are such compounds.
Based on the principle of carbon-14 dating and the characteristics of cartilage tissue, a group of Danish scientists (including orthopaedic surgeons, oncologists and astrophysicists) collected tibial cartilage tissue that had undergone artificial knee arthroplasty or amputation due to degeneration or tumor, including 15 degenerative worn knee joints and 8 normal knee joints (from 7 tumor amputation patients and one donor), and analyzed and dated the ratio of collagen to glycosaminoglycans to C14.
After enzyme decomposition, stratification and purification, they found that the collagen of the cartilage located at the knee joint ** stayed at the carbon-14 ratio of 11 years old on average; The cartilage around the knee joint remained at an average age of 13 years, and there was no significant difference between the degenerative and normal groups. This means that after the age of 13, cartilage no longer metabolizes carbonaceous compounds!
On the other hand, the ratio of C14 in glycosaminoglycans was close to that of C14 at the time of surgical sampling, indicating that its synthesis lasted for life.
This experiment confirms the fact that knee cartilage cannot be regenerated.

Anonymous users2024-02-07Articular cartilage plays an important role in joint activity, and its structure is delicate and scientific. Cartilage can be divided into three types: hyaline cartilage, elastic cartilage, and fibrocartilage (mainly distributed between the lumbar vertebrae) according to the fiber composition contained in cartilage tissue. The surface of the articular cartilage is smooth, pale blue, and shiny.
Cartilage tissue is made up of chondrocytes, matrix, and fibers. Chondrocytes, on the other hand, gradually change from flat to oval or round from superficial to deep, and these chondrocytes maintain the normal metabolism of articular cartilage. Articular cartilage has no innervation and no blood vessels, and its nutrients must be obtained from synovial fluid, and its metabolic waste products must also be discharged into synovial fluid, so it can be said that the nutrients provided by synovial fluid determine the normal operation of articular cartilage and the normal use of human joints.

Anonymous users2024-02-05What to eat helps cartilage regeneration
Cartilage is very important for the body, these are also born in the body, so if there is a lack of human bone or cartilage injury, then what should we do, let's take a look at what to eat to help cartilage regeneration.
What to eat helps cartilage regeneration
In the structure of bone, the structure related to his growth, more is filial piety in the cartilage layer and osteoblasts, so in childhood, because of his cartilage layer, it will continue to produce new cartilage layer, he will grow up slowly, so it has the function of regeneration, can do a healing effect on different cartilage that forms new cells.
And the human body needs a lot of nutrients in the process of growth, various mineral elements, various trace elements, and enough caloric intake required for daily shrinkage are very important, which can promote growth and growth, especially for women, in the ** period of growing taller, that should strengthen the intake of nutrients, such as protein and the intake of various dairy products, then eat more fish in life, fish is rich in protein, and it will not lead to weight gain.
Eating some foods that are conducive to cartilage regeneration, relatively speaking, there is no such statement, it can only be said that eating some foods that can help the body to quickly renew cells can help the body's metabolism.
Exercises such as climbing mountains and stairs can wear down the cartilage in the knee joint, especially when descending hills or stairs. Cartilage is difficult to recover after wear and tear because the cartilage itself has no vascularity and no nutrients**.
Synovitis is mainly caused by obstruction of microcirculation, bursa secretion of synovial fluid production is greater than absorption, the principle is to regulate and dredge microcirculation, as long as the microcirculation is completely unblocked, do not exercise with weight before the elimination of stagnant water, try to avoid going up and down stairs and squatting activities, avoid cold, otherwise it is easy to wear cartilage, it is recommended to use traditional Chinese medicine**. In terms of clinical practice, at present, major hospitals in China often use the method of combining traditional Chinese and Western medicine, such as the combination of Gutaishu and aspirin developed by China Medical University, which has a relatively ideal curative effect.
Hello, one reason why your uncle's knee joint can't bend is that the ligament is also broken and strained at the same time as the fracture, and the second reason is that the ligament inside is artificially cut due to the open surgery, and the ligament is ruptured and strained, and the joint bending is generally inconvenient, and the early activity is swollen, and the ligament injury itself is difficult to repair, so after three years, your uncle's knee joint still can't get normal bending, and surgery is not recommended for ligament injury, and the operation is just to pull the ruptured ligament together. In fact, they are not really connected to each other's growth, and the use of traditional Chinese medicine ** can solve such a problem, directly with the external application of traditional Chinese medicine, the ligaments can regrow and connect, early ligament injury (within 1 to 3 months)**30 days or so can be basic**. Between 3 months and 5 months, it takes about 40 to 50 days to be basic. Because your uncle's ligament injury missed the early stage, and it was delayed for such a long time, it is very difficult to return to normal, and it can be said that it can only recover to about 50%. >>>More
