The maintenance time of traumatic osteoarthritis is related to the patient’s condition, physical fitness and treatment modality, and there are more obvious individual differences, with the maintenance time ranging from 5 to 20 years. Traumatic osteoarthritis is caused by severe traumatic injuries to the joint surfaces or articular cartilage, limiting joint stability and mobility. If the damage to the joint surface is mild, patients should pay attention to reducing activities and weight bearing in daily life, actively exercising the muscles around the joints, and regularly injecting sodium vitrate to protect the joints, and the joint function can be maintained for 10 to 20 years. If the damage to the joint surface is severe, patients do not pay attention to protection in daily life and do not actively carry out treatment, the wear and tear of the joint surface will be aggravated, and the joint function can only be maintained for 5-10 years, and a small number of patients may be maintained for a shorter period of time, and later need to be replaced by artificial joints. When traumatic arthritis occurs, it is recommended that patients go to the orthopedic department in time for examination and treatment under the guidance of doctors to avoid aggravation of the condition.
