Osteoarthritis occurs in the interphalangeal joints, hip joints, knee joints, and cervical and lumbar joints. According to the epidemiological survey data, there are differences in the occurrence of osteoarthritis in different regions of the population, in general, for symptomatic osteoarthritis, the incidence of cervical, lumbar and knee joints is high. From the analysis of the etiology of osteoarthritis, the knee and hip joints are load-bearing, and osteoarthritis of the knee and hip joints is more common in obese patients; and for the joints that are subjected to great pressure and have more wear and tear, such as the cervical spine and lumbar spine are also susceptible to the onset of the disease. Osteoarthritis is characterized by joint pain, dysfunction and deformity, involving only a single joint in the early stages and multiple joints in the later stages. For the majority of patients, improving diet and losing weight can help prevent osteoarthritis.
