SummaryWhat are the key points about arthroscopic anterior cruciate ligament (acl) reconstruction for anterior cruciate ligament - acl - tear? Tears or 'ruptures' of the anterior cruciate ligament (ACL) are
treatable using arthroscopy and minimally-invasive surgical techniques.
The surgical success rates for ACL reconstruction exceed 95%. The
anterior cruciate ligament (ACL) is one of the major supportive
ligaments in the knee. It extends from the lower leg bone (tibia) to
the thigh bone (femur) at the knee. This ligament primarily helps
control knee motion by preventing excessive forward movement of the
tibia in relation to the femur.
While the
ACL is not the most commonly injured knee ligament, tears of this ligament
frequently lead to chronic knee instability or “giving way”. ACL tears most commonly result during
athletics from vigorous cutting, landing, deceleration or twisting
injuries. It is less common for injuries
to result from physical contact or collisions during athletics. Many
patients who suffer an ACL tear will know immediately that something “feels
wrong” with the knee. Many patients
report feeling or hearing a “pop” associated with pain and a sense of “giving
out”. The joint will typically swell
within several hours which results in restricted motion of the knee. It will become uncomfortable to bear weight
on the injured leg, and the patient will prefer to walk with assistive devices
for added support, such as crutches or a cane.
The patient may experience the knee “giving way” when stressed with
simple activities such as walking or changing directions. In the
past, injuries to the ACL prohibited athletes from returning to “cutting” or
“pivoting” high-demand sports.
Currently, advanced surgical techniques reliably allow the return to athletic
activities and physically demanding labor within 6 months. The goals of surgically reconstructing the
ACL are to decrease the time lost to the injury, avoid additional injury to the
knee, and to return to unlimited participation in functional and athletic
activities. There are many different
ways that the ACL can be reconstructed, and depending on the age, activity
level, gender, and expectations of the patient.
