When an individual has an ACL<unk> , they are likely to hear a "pop" in their knee followed by pain and swelling. They may also experience instability in the knee once they resume walking and other activities, as the ligament can no longer stabilize the knee joint and keep the tibia from sliding forward. Reduced range of motion of the knee and tenderness along the joint line are also common signs of an acute ACL<unk> . The pain and swelling may resolve on its own; however, the knee will remain unstable and returning to sport without treatment may result in further damage to the knee.
