The recovery time of acute double knee osteoarthritis is generally between 2 weeks and 4 weeks, but also according to the patient’s ability to recover and the progress of the disease, there is no uniform recovery time standard. Acute osteoarthritis of both knees is mostly due to the abnormal metabolism of the cartilage in the knee joints, or due to the knee joints being affected by external stimuli, joint damage and other factors leading to acute inflammation of the knee joints, and the clinical symptoms are mostly pain, swelling, and limited joint movement. Clinical symptoms include pain, swelling and limitation of joint movement. Oral non-steroidal anti-inflammatory drugs such as diclofenac sodium can be prescribed for anti-inflammatory and analgesic treatments, and glucosamine, chondroitin and sodium hyaluronate can be used to improve the symptoms and to protect the articular cartilage. Patients with acute double knee osteoarthritis should go to the hospital in time and under the guidance of the doctor for scientific treatment.
