The treatment time of osteoarthritis varies from person to person: 1. For patients with mild symptoms, most of them can obtain satisfactory treatment effects through timely comprehensive treatment such as medication, exercise training and physical therapy, and the symptoms can be significantly relieved within 1 month of treatment; 2. For patients with osteophytes and cartilage wear, the hospitalization time is relatively long and the medication should be maintained for 1-3 months after discharge; 3. For patients with severe symptoms, conservative treatment may be ineffective and surgical intervention is required.
