How long it takes to recover from ankle fusion depends on the patient’s specific condition, and generally it takes about 3 months. Ankle fusion is suitable for patients with secondary pain caused by traumatic arthritis, septic arthritis, rheumatoid arthritis, etc., which cannot be improved by conservative treatment and have poor ankle function. During the surgery, the damaged joint surface is removed, autogenous or artificial bone is implanted, and internal fixation is performed. After surgery, the ankle joint is usually immobilized in a cast or brace to stabilize the joint and achieve local osseous fusion, which generally takes about 3 months to achieve. If the patient is in poor health or has poor bony healing, the recovery time may be longer. Patients with ankle fusion surgery are advised to go to the hospital for regular checkups, perform active functional exercises under the doctor’s guidance, and pay attention to a nutritious diet with more protein and calcium-rich foods to promote early recovery. If you have any discomfort symptoms, you should actively consult the doctor for review.
