What happens when joint cartilage is lost? – VnExpress

Cartilage is very important for joints, the loss of cartilage causes the joint space to narrow, causing osteoarthritis, degenerative joint diseases … leading to pain and inflammation.

The body contains three different types of cartilage: hyaline cartilage, elastic cartilage, and fibrocartilage. Hyalin cartilage, also known as articular cartilage, is a familiar type of cartilage, they form a thick layer on the ends of bones in joints. This type of cartilage is also found in the nasal septum and trachea. In osteoarthritis, cartilage loss is an important factor that contributes to disease progression.

Cartilage is very smooth and has low friction, which allows the bones in the joint to move easily during movement. Articular cartilage also acts as a cushion and shock absorber for joints. When cartilage is damaged or worn away, the affected joint becomes painful, stiff, and limited in motion. These are the symptoms that patients need to see a doctor to detect joint disease.

At that time, there is little or no cartilage left to act as a shock absorber. Loss of cartilage in one or more joints can cause pain and eventually lead to limited function and even disability, so early detection and treatment is essential. Besides causes such as excessive exercise that causes joint and cartilage damage and wear and tear, cartilage can degrade over time for many different reasons.

Progressive cartilage degeneration causes pain and inflammation, with severe osteoarthritis the cartilage can be completely worn away causing the affected joint to lose its cushioning and begin to rub against bone. Patients will experience joint pain, loss of motion and even loss of function in relation to the affected joint.

Damage to articular cartilage can be seen on X-rays, is a narrowing of the joint space between bones. In the knee, the loss of articular cartilage is usually the loss of meniscus. This puts extra stress on the ends of the bones that make up the joint, which form the bone-forming substances, or the bony shoots right at the edge of the joint.

Research has shown that the top risk factors that contribute to rapid cartilage loss include cartilage damage, meniscus tears, and other serious injuries that can be seen on MRI. Bursitis and joint effusion are also causes of cartilage loss. Being overweight or obese is also considered a risk factor, with every increase in body mass index (BMI), the risk of cartilage loss also increases by 11%.

Joint cartilage can be restored by a variety of treatments. Surgery is a procedure in which new cartilage cells are transplanted, or a doctor can remove a portion of healthy bone and cartilage from another area for transplantation. Currently, this procedure mainly treats knee injuries. Arthroscopic procedures include arthroplasty with micropoint osteotomy, drilling, and abrasion. This helps create small areas of damage and stimulates cartilage to regrow.

Medications are used to control osteoarthritis and other types of arthritis, and healthy body movement also helps preserve cartilage. Depending on the condition of the disease, the specific treatment method will depend on the disease condition and prescribed by a specialist doctor.
