Pain may exist associated with the physical therapy regimen. In the absence of an intact ACL – fifty-fifty when no other injury is nowadays – the menisci (pads of cartilage that cushion the bones that meet at the articulatio genus articulation) have a higher risk of injury. If a tear forms in 1 or both menisci of the knee, pain and swelling may occur.
