Plan on getting up and moving the same day or the day after surgery. You’ll be using crutches or a walker to get started. Usually you can discard the walking aid in two to four weeks, depending on how fast your thigh strength returns and the swelling goes down. Don’t expect to return immediately to the activities that resulted in your injury.
Returning to sports activities really depends on the treatment plan set up by your doctor and physical therapist. It also depends on your progress in rehabilitation after surgery. Treatment protocols after ACL surgery are generally designed to take between four and six months. Be sure to ask your doctor if you have questions about the activities you’d like to do.
