After surgery, the ankle joint was kept in a neutral position to place a subtalar splint. Drainage tubes were removed 2 days after surgery, wounds were changed and immobilized in a short tubular cast of the lower leg. The affected limb was elevated for 2 days, after which full weight-bearing was allowed, and patients were asked to walk for up to 10 minutes at a time with full weight-bearing on one lower limb. Alternate weight bearing and rest for both lower limbs. The Americans advocate 6 weeks of postoperative subtalar tubular cast immobilization in a neutral ankle position. The cast can be removed after 4 weeks for osteoarthritis of the ankle and 6 weeks for rheumatoid arthritis of the ankle. After removal of the cast, the patient was instructed to practice walking and the physical therapist instructed ankle mobility and balance training. Two days later, intermittent weight-bearing walking for 10 minutes, 3~4 weeks later (non-cemented fixation) to remove the cast, pay attention to the exercise of foot muscles and the back of the calf muscles. The ankle joint may be swollen in 3~6 months after the surgery, and the affected limb can be intermittently immobilized with elastic bandage or intermittently elevated. Wu Gang, Minimally Invasive Foot and Ankle Surgery Department, Affiliated Rehabilitation Hospital, National Rehabilitation Aids Research Center The Germans believe that if bone cement is used, the external fixation should be removed after 14 days. If no bone cement is used, external fixation must be retained for 3 to 4 weeks. After the mold is removed, patients are recommended to do squatting exercises with the heel on the ground. Patients should also perform tiptoe standing exercises to strengthen the muscles of the lower extremity. The surgical area of the ankle can remain swollen for up to 3 to 4 months. During this time, patients usually experience tugging pain after exercises or at night. The use of compression stockings and elevation of the affected limb can be helpful in relieving pain. Symptoms remaining after 12 months postoperatively are permanent.
