6 main causes of osteoarthritis in joints

It is also called degenerative arthritis and hyperplastic arthritis. It is a chronic disease in which the body's joints gradually deteriorate and bone hyperplasia declines. There are many patients suffering from osteoarthritis, especially middle-aged and elderly people. Today I will take you to understand the causes of osteoarthritis of the joints.

Causes

1. Aging: Aging is a strong risk factor for the development of osteoarthritis. Autopsy data show that about 5% of people have degenerative changes in their joints starting at the age of 20. By the age of 40, almost 90% of weight-bearing joints have more or less bone hyperplasia changes.

2. Gender : According to authoritative data analysis, the incidence rate of females is twice as high as that of males before the age of 50, but after the age of 50, the incidence rate between the two sexes is basically equal.

3. Occupation : Bone hyperplasia is related to occupation. Long-term and repeated use of certain joints can cause an increased incidence of disease in these joints. Such as the elbow and shoulder joints of foundries, the spine and knee joints of miners, the knee and ankle joints of loaders, the shoulder joints of drivers, the wrist joints of repairmen and textile workers, the metatarsophalangeal joints of ballet dancers, the cervical vertebrae of people who have been engaged in embroidery, typing, and desk work for a long time, and the heel bones of people who work in a standing position for a long time, such as textile workers, salespersons, receptionists, and ceremonial guard members. The above-mentioned parts are often worn out and cause bone hyperplasia due to long-term and repeated movements. The 1994 "Annals of Rheumatology" pointed out that by comparing 109 male and female patients aged 50 and above with osteoarthritis with 218 people without osteoarthritis, it was found that people who squatted or kneeled for more than 30 minutes a day or climbed more than 10 flights of stairs a day had a significantly higher incidence of knee bone hyperplasia.

4. Racial genetic factors: The incidence rate is high in the British and low in West Africans, and higher in Caucasians than in blacks. The incidence rate of women with osteoarthritis with Heber-den nodes, their mothers and sisters, is 2 to 3 times that of the general population. The detection rates of HLA-A1 and HLA-B8? in patients with osteoarthritis are also increased. ?

5. Physical factors: Weight gain adds heavy load to already worn and degenerate joints, making them more easily damaged. Therefore, bone hyperplasia often occurs in areas with heavier loads such as the hip, knee, calcaneus, and lumbar spine. In addition, due to joint pain, patients unconsciously limit their activities and gain weight, and the mutual influence aggravates joint disease. A research report published in the American magazine "Arthritis Today" pointed out that by tracking and observing 1,178 men aged 30 to 46, it was found that those who were 20 pounds above the standard weight were 3.5 times more likely to develop osteoarthritis than those with normal weight. The most common sites of occurrence are the hip and knee joints.
