After ankle surgery, the most important thing to do is to rest your ankle. The ligaments in your ankle are still healing, and walking or putting weight on the ankle can cause them to tear again or even to break. You should not put any weight on your ankle for at least two weeks after surgery. Even then, you must walk with a cane or crutches and have someone help you until your strength comes back. After that time has passed, you can begin physical therapy. The therapist will have you do exercises to strengthen the muscles in your leg so that you have better balance and more control over the motion of the foot and ankle. This is extremely important because it helps minimize re-injury once you begin putting weight on your foot again.
