ACL reconstruction is required if the instability due to damaged ACL fibers is limiting the activity level of patient to a significant extent; or if the patient wants to pursue an active athletic activity/ sport.
ACL has two bands of fibers which interlace with each other.
Anteromedial and Posterolateral;
Of these, Posterolateral fibers are most important from patho-mechanical point of view.
Acl reconstruction is widely performed using two techniques viz.
1) Bone patellar tendon bone graft
2) Double bundle Hamstring graft
The superiority of one method over the other has not been proved conclusively, so far.
Most patient after ACL reconstruction return to pre-injury status after 6 weeks,and are allowed to pursue active sports after 6 months.
ACL reconstruction can now be performed as a day-care surgery.
