Researchers have shown that certain types of treatment can help restore balance after ACL surgery. They suggest rehabilitation with three components. One component is training to improve range of movement in the knee. Another is agility training to exercise and quicken the reflexes. The final component is strength training, especially of the hamstring muscles.
A recent study looked at patients who had this type of rehabilitation three times a week for at least six months after ACL surgery. Results showed that these patients were able to balance about as well as people who never had ACL problems.
A physical therapist can suggest a training program to help you maximize your recovery after surgery. If you stick with your program, you have a good chance of getting your balance back.
