The treatment of ankle synovitis in the clinic is mainly based on conservative treatment. Ankle synovitis is mainly caused by excessive local joint movement, as well as chronic strain and other factors. Conservative treatment is the mainstay of clinical treatment, and non-steroidal drugs such as ibuprofen, diclofenac sodium and other anti-inflammatory drugs can be taken in accordance with the doctor’s instructions, and if necessary, with localized hot compresses, tuina, acupuncture, as well as baked electricity and other physiotherapy modalities for treatment. Patients with ankle synovitis should rest in bed at an early stage, elevate the affected limb, and use an elastic bandage to apply pressure. During the treatment period, the quadriceps muscle can be used for stretching activities. In the late stage of synovitis, the knee flexion and extension exercises should be strengthened, which has a positive effect on eliminating joint effusion, preventing quadriceps atrophy, preventing recurrence of synovitis, and restoring the knee flexion and extension functions. Because each synovitis patient’s physical condition and condition is different, so the specific treatment method is recommended to follow the doctor’s advice to choose.
