ACL reconstruction is a surgical procedure aimed at repairing a torn anterior cruciate ligament, a key ligament in the knee that helps stabilize the joint. This injury often occurs during sports activities, leading to pain, swelling, and instability in the knee. The surgery typically involves replacing the damaged ligament with a graft, which can be taken from the patient’s own body or a donor. After the surgery, patients usually undergo a rehabilitation program to restore strength and mobility. Recovery can take several months, and the goal is to return to normal activities, including sports, while minimizing the risk of re-injury.
