Initial evaluation includes a medical history, physical examination, and x-rays
to rule out other associated conditions. Specialized examination maneuvers to test
the integrity of the ACL and other structures in the knee may be done. An MRI is
indicated in those where there is a suspicion for an ACL tear.
Treatment of ACL tears is dependent on age, activity level, and desire to return
to activity. ACL tears do not heal though nonsurgical treatment may be indicated
in those without knee instability or who are interested in activity modification
and possibly bracing. For those who desire return to previous activity level, surgical
treatment is recommended. This is done arthroscopically as an outpatient and several
options exist in regards to graft. Regardless of treatment, rehabilitation plays
a critical role. A physical therapy program will help regain knee strength and motion
and typically lasts until the knee is equal to the other side.
