Surgery is only a key step in the treatment, and postoperative rehabilitation plays an equally important role. For this reason, we recommend that you still need to pay attention to the following after lateral collateral ligament repair of the ankle: 1. No weight-bearing for 2 weeks after the operation, then wear a weight-bearing cast in a neutral position for 3 weeks, and then replace it with a walkable foot boot for 3 weeks. 2. 2. Use of a circumferential ankle brace within the boot to control rotation until the end of physical therapy, and continue to wear it when playing sports for 1 year. 3. Physical therapy was started 8 weeks after surgery. 4.Patients were scored at the beginning of physical therapy and again before the 4-month review. 5.Sports are resumed 4 months after surgery.
