Osteoarthritis (Osteoarthritis), also known as degenerative arthritis, is the most common arthritis in the world. Its manifestations and progression vary from person to person. It is more common in large weight-bearing joints of the lower limbs. The three major symptoms are joint pain, stiffness and With limited movement, patients may also experience muscle weakness and balance problems.
Osteoarthritis (OA) of the knee happens when cartilage wears away in a joint, and the bone starts to erode. Apart from tissue damage, you’ll probably start to experience pain and inflammation.
Some dietary choices can help you take care of your joints.
In this article, find out what you can eat to help boost the health of your knee joints.
Especially the impact of knee osteoarthritis is similar to that of cardiovascular disease, which is greater than the impact of any other disease on patients
In empirical medicine, what health ingredients are helpful for osteoarthritis, please refer to the article analysis for details?
What is osteoarthritis?
Osteoarthritis is the most common type of arthritis. It is a degenerative joint disease characterized by damage to the structure and function of articular cartilage (narrowing and thickening of the joint space, osteophyte formation, and subchondral bone cyst) , The reason is the imbalance of anabolic and catabolic processes in cartilage tissue, which leads to its degradation
Osteoarthritis affects approximately 5% to 15% of the world’s population and often causes moderate to severe disability, making it the 11th most debilitating disease in the world.
It is estimated that 80% of people over 65 have radiological evidence of osteoarthritis, although only 60% of this group of people have symptoms.
Typical osteoarthritis often involves the proximal and distal interphalangeal joints, the first carpal-metacarpal joint, the hip joint, the knee joint, the first metatarsophalangeal joint, the lower cervical and lumbar joints. It can be single or multiple joints. Articulated
Classification of osteoarthritis?
Osteoarthritis is mainly divided into two categories: primary osteoarthritis and secondary osteoarthritis.
Primary osteoarthritis is the most common collection of the disease. The diagnostic criteria is that there is no induced trauma or disease factors, but it is related to the above risk factors.
The occurrence of secondary osteoarthritis is related to pre-existing joint abnormalities. Related conditions include trauma or injury, congenital joint disease, inflammatory arthritis, avascular necrosis, infectious arthritis, Paget’s disease (Paget disease), osteonecrosis, osteochondritis exfoliating (osteochondritis dissecans), hemochromatosis, Wilson’s disease, hemoglobinopathy, Ehlers-Danlos syndrome ) Or Marfan syndrome (Marfan syndrome)
What are the health ingredients that are helpful for osteoarthritis?

Glucosamine
Glucosamine is an amino sugar (also known as amino glucose), which is an important molecule in the biochemical pathway of glycosylated protein and lipid synthesis. It is abundantly present in articular cartilage, intervertebral disc and synovial fluid. It is also a large extracellular matrix. The main components of molecules such as glycosaminoglycans (GAGs), glycolipids and acetylated glycoproteins.
Glucosamine is a special non-vitamin, non-mineral supplement, often combined with chondroitin and methylsulfonylmethane for osteoarthritis and non-specific joint pain.
Although the effectiveness of these supplements is controversial, they are still one of the most commonly used ingredients, and their use rate is equivalent to that of anti-inflammatory and painkillers: acetaminophen
＊Conclusion: As of now, for osteoarthritis, there is insufficient evidence to support that oral glucosamine can delay the natural course of continuous joint degeneration, but it may be slightly helpful for pain relief

Curcumin
Turmeric has been used in traditional Chinese medicine and Ayurvedic medicine in Asian countries for thousands of years. It is a Chinese herbal medicine for the treatment of liver disease, rheumatoid, diabetes, atherosclerosis, infectious diseases and cancer
Among them, the most effective ingredient, Curcumin, is a polyphenol compound extracted from turmeric rhizomes. It is characterized by its antioxidant, anti-inflammatory, anti-mutagenic, antibacterial, antimicrobial, anti-arthritis, and neurological properties. Protective activity
Curcumin has low bioavailability and poor water solubility. Therefore, in order to improve the utilization of curcumin, various mechanisms have been developed to enhance the absorption rate, such as emulsion, encapsulation and nanoparticle type.
＊Conclusion: For primary knee osteoarthritis, oral curcumin may be helpful for pain and quality of life improvement, but due to the small number of samples and heterogeneity, more studies are needed to support it

Non-denatured type II collagen
Collagen is mainly found in skin, hair, nails, muscles, tendons, ligaments and joints. It mainly provides tissue tension and strength, and has the effect of promoting wound healing and tissue repair
There are currently more than 29 types of collagen in the human body, 90% of which belong to the first to fifth types, and the most common type of articular cartilage is Type II Collagen.
Undenatured Collagen Type II (UC-II) is a new generation of clinically proven patented ingredients. The difference from hydrolysed collagen (hydrolysed) is that UC-II is made at low temperature. , Without enzymatic decomposition, maintain the triple helix structure of collagen and retain the most biological activity
The special feature of UC-II is that it can act on Peyer’s patches in the intestines, and then train immune cells to recognize their structures. It has an immunomodulatory effect (also known as oral tolerization), thereby preventing T cells The attack on the type II collagen structural protein in cartilage reduces the inflammation reaction of articular cartilage and promotes joint health. Note 1
＊Conclusion: The use of non-denatured type 2 collagen may have a positive effect on the improvement of osteoarthritis, but it is limited by the small number of samples and still needs more large-scale trials to support it
6 common questions about knee osteoarthritis
- Need surgery to treat knee osteoarthritis?
Answer: Although most patients do not need surgery, surgery is necessary for those with severe pain or joint damage.
- Can I wear high heels for knee osteoarthritis?
Answer: In fact, wearing high heels for a long time will cause you to walk, which will change the stress on the joints, which may lead to degeneration and increase the risk of knee osteoarthritis.
- Is the weather related to knee osteoarthritis?
Answer: Rainy weather does not cause knee osteoarthritis, but some people may increase pain on rainy days.
- If the parent has knee osteoarthritis, is the child more likely to develop knee osteoarthritis?
Answer: People with a family history are at higher risk of knee osteoarthritis, but a healthy lifestyle can avoid reducing the prevalence
- For every pound of weight gain, there will be an equal amount of pressure on the knee?
Answer: wrong. A weight gain of 1 pound (0.45 kg) is equivalent to about 2 to 4 pounds (0.9 to 1.8 kg) of pressure on the knee.
- Is knee osteoarthritis a normal result of aging?
Answer: wrong. Although knee osteoarthritis is related to aging, it is not an inevitable result.
Summary: The health of joints is related to whether we can move freely and unrestricted, but don’t think that degenerative arthritis can only be obtained by the elderly, because patients have been younger, obesity, occupational injuries, infections, genetics will all increase the risk Probability
So don’t wait until there are problems before you start paying attention. You must pay attention to maintenance since you are young. Generally speaking, as long as you avoid overweight, develop exercise habits, strengthen the muscles of your legs, and take in the correct nutrients, you can reduce the chance of joint degeneration. So you can walk like flying
