Walking can be done about a month after ACL reconstruction. The anterior cruciate ligament (ACL) plays an important role in keeping the knee joint stable and preventing excessive bending of the knee. ACL reconstruction is required after an ACL injury or rupture. Sufficient rest is required after surgery to allow the reconstructed stop ligament to heal into the bone tissue. Walking can usually be practiced in about one month, and normal exercise can be resumed in about three months. After ACL reconstruction, it is not advisable to carry out weight bearing too early, and it is necessary to ensure sufficient rest. After the surgery, you can carry out appropriate exercises to help the recovery, and you should supplement your daily nutrition, keep your body and mind happy, and carry out rehabilitation training in a timely manner after the surgery.
