The correction methods for ankle exostosis caused by different reasons are different, as follows: 1. Improper walking posture: Generally, the ankle exostosis can be gradually corrected by using corrective shoes, such as applying corrective pads at the heel, especially by padding the medial side of the heel bone. 2. Torn ligaments of the ankle joint: For example, if the medial deltoid ligament is torn, the medial joint is often lax and ankle exostosis will occur. For complete correction, reconstruction surgery of the medial deltoid ligament is usually required. 3. Flatfoot syndrome: reconstruction surgery of the heel of the flatfoot is usually required, and the degree of ankle valgus will be corrected after reconstruction of the heel.
