What Causes Pain In The Knees?

ACL Injury

An ACL injury involves a partial or complete tear of the anterior cruciate ligament in the knee. Patients who play contact sports such as soccer, football, and basketball are at an especially high risk of this type of injury. Running diagonally down the center of the knee, the anterior cruciate ligament is responsible for the rotational stability of the joint, and it also ensures the tibia stays in place. Doctors use the term 'sprain' to describe an injured ligament, and ACL sprains are divided into three categories according to severity. Most ACL injuries are complete or nearly complete sprains; these are much more common than partial tears of the ligament. Patients who have had an ACL injury might hear a popping noise at the time of the injury, and they could feel their knee give out from under them. There might also be discomfort while walking, and the knee generally swells within twenty-four hours of the injury. ACL injuries are typically treated with surgery using a tissue graft to reconstruct the ligament.
