How to restore worn knee cartilage?

Wear of knee cartilage can cause serious effects on the human knee and even cause a series of diseases. Therefore, if you find that you have wear of knee cartilage, you need to seek medical treatment in time. Glucosamine is significantly effective in helping the recovery of worn knee cartilage, but it is not suitable for use by pregnant women, people who are allergic to seafood, etc.

1. What is cartilage and what is its function?

Cartilage is histologically divided into hyaline cartilage, fibrous cartilage and elastic cartilage. Articular cartilage is a hyaline cartilage with a smooth surface, milky white to light blue color, and is translucent. It is attached to the surface of the bone. A typical example of fibrous cartilage is the meniscus, which is sandwiched between two bone surfaces. Elastic cartilage is distributed in the auricle and epiglottis. All joints in the human body must have cartilage, which has the function of buffering pressure, lubricating joints, and avoiding direct friction between bones. In the joint cavity, all the nutrition for the joint comes from the subchondral bone.

2. Can Glucosamine Really Repair Cartilage?

Glucosamine is not a drug, but a component in the body. Its full name is D-glucosamine, which is a monosaccharide component that can be extracted from crab and shrimp shells. It is an important component of highly hydrophilic proteoglycans, one of the important nutrients for the formation of chondrocytes, and a basic component of cartilage matrix and synovial fluid.

Glucosamine strongly stimulates chondrocytes to synthesize collagen and hyaluronic acid in the human body, thereby continuously lubricating the articular cartilage surface, reducing wear and tear, and making the joints flexible. It can also generate new articular cartilage and synovium, thereby restoring the normal physiological function and incapacitated function of the joints. At the same time, it also has a good repairing effect on the damage to articular cartilage cells caused by long-term use of anti-inflammatory and analgesic drugs. Glucosamine can not only inhibit the inflammatory response of nonspecific factors and relieve pain, but also eliminate harmful enzymes in the joint cavity and enhance the immunity of joints and the body. Promoting immunity through glucosamine supplementation is an important prerequisite for eliminating joint inflammation.

3. Who is not recommended to take glucosamine?

1. Glucosamine is made from crab or shrimp shells, so it is not recommended for people who are allergic to seafood;

2. It is not recommended to use during pregnancy or breastfeeding;

3. Patients with cardiovascular and cerebrovascular diseases such as hypertension are not suitable for long-term and large-scale use of low-purity glucosamine sulfate products.

4. Due to differences in personal constitution and individual medical conditions, the side effects of taking glucosamine are also different. It is recommended that patients with stomach problems take the medicine after meals and try to use high-purity glucosamine sulfate.
