The severity of primary osteoarthritis needs to be judged on a case-by-case basis. If there is only mild synovial inflammation, it is not very serious; if there is serious damage to the off cartilage and obvious osteophytes, it is more serious. Primary osteoarthritis is relative to secondary osteoarthritis, osteoarthritis without obvious causes, mostly in the hip joint, knee joint and other weight-bearing joints. Common symptoms include joint pain, swelling, and difficulty moving. The severity of primary osteoarthritis needs to be judged according to the degree of destruction of the joints. If there is only mild synovial inflammation, it is not very serious, while it is more serious if there is severe damage to the joint cartilage and obvious osteophytes, which seriously affects the function of the joints. After diagnosing primary osteoarthritis, it is recommended to take into account your own situation and treat under the guidance of your doctor.
