 In the U.S., there are about 100,000-200,000 ACL ruptures per year and about 100,000-150,000 ACL repairs per year. (Mall et al., 2014) These numbers are based on data from several years ago, thus may be higher today due to more younger individuals engaging in high-level sports and more older individuals staying active longer. The current incidence of ACL injuries and repairs is unknown. (Mall et al., 2014) The higher number of ruptures than repairs is due to those who opt for non-surgical treatment.
-ACL injuries generally occur beginning in late adolescence. Ages leading up to late adolescence do not typically sustain ACL injuries, but rather sustain growth plate injuries due to the relative weakness of the cartilage at the epiphyseal plate compared with the ACL. (Cimino et al., 2010)

 For the clinical examination of a suspected ACL injury, the pivot-shift test, anterior drawer test and Lachman test are used.
+<HTML>

+</HTML>
 The pivot shift is difficult to perform in the office, it is usually more helpful in the operating room with a patient under the influence of anesthesia. The pivot shift maneuver identifies abnormal motion of the knee joint when there is an ACL tear present.

 The drawer test is used in the primary clinical assessment of suspected rupture of the cruciate ligaments in the knee. During the test, the patient should be supine with the hips flexed to 45 degrees, the knees flexed to 90 degrees and the feet flat on table.
+<HTML>
+<br>
+</HTML>
 The Lachman test is known by most authorities as the most reliable and sensitive test, and usually a better alternative to the anterior drawer test. The ACL can also be detected using a magnetic resonance imaging scan (MRI scan).
+<HTML>
+<br>
+</HTML>
 Even though clinical examination if done by a professional can be accurate, the diagnosis is usually confirmed by MRI scan, which has significantly narrowed the need for diagnostic arthroscopy and which has a greater accuracy than clinical examination. It may also show a graphic of other structures which may have been involved in the injury, such as a meniscus, or collateral ligament, or posterolateral corner of the knee joint.
