What is the cause of osteoarthritis

Incidence rate is proportional to age. With aging, repeated use of the knee can stimulate inflammatory changes in cartilage. In addition, the content of mucopolysaccharide in aged cartilage decreases, the matrix loses chondroitin sulfate, the toughness decreases, and it is easy to be injured by mechanics and produce degeneration. Especially in women over 45 years old, about 60% of women over 50 years old will be affected by the disease.

The second reason: obesity: obese weight increases the load of joints, and changes in posture and gait lead to changes in joint biomechanics. The most common site of knee osteoarthritis in obese people is medial cartilage. If they are obese and lack of exercise, they will easily suffer from this disease.

The third reason: heredity: this inference is based on the different prevalence of osteoarthritis in different races and different populations.
