Welcome to our comprehensive guide on ACL (Anterior Cruciate Ligament) tears and ACL reconstruction. As a patient, it's essential to have a clear understanding of these topics to make informed decisions about your health. In this article, we will explore what an ACL tear is, when ACL reconstruction is indicated, the risks and benefits of the procedure, expected outcomes, and other potential injuries associated with it.
What is an ACL Tear?
The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the center of the knee running from the femur to the tibia. When this ligament tears unfortunately, it does not heal and often leads to the feeling of instability in the knee.
ACL reconstruction is a commonly performed surgical procedure and with recent advances in arthroscopic surgery can now be performed with minimal incision and low complication rates. The advancements in arthroscopic surgery make it easy for surgeons to see and work on knee structures through small incisions. Repair of the torn ligament can be performed at the same time as the diagnostic arthroscopy with fewer surgical risks.
The surgery can usually be done as an outpatient procedure which means you may be discharged to go home on the same day as the procedure.

Causes
An ACL injury most commonly occurs during sports that involve twisting or overextending your knee. An ACL can be injured in several ways:
- Sudden directional change
- Slowing down while running
- Landing from a jump incorrectly
- Direct blow to the side of your knee, such as during a football tackle

Symptoms
When you injure your ACL, you might hear a loud "pop" sound and you may feel the knee buckle. Within a few hours after an ACL injury, your knee may swell due to bleeding from vessels within the torn ligament. You may notice that the knee feels unstable or seems to give way, especially when trying to change direction on the knee.
Diagnosis
An ACL injury can be diagnosed with a thorough physical examination of the knee and diagnostic tests such as X-rays, MRI scans and arthroscopy. X-rays may be needed to rule out any fractures. In addition, your doctor will often perform the Lachman’s test to see if the ACL is intact. During a Lachman test, knees with a torn ACL may show increased forward movement of the tibia and a soft or mushy endpoint compared to a healthy knee.
Pivot shift test is another test to assess ACL tear. During this test, if the ACL is torn, the tibia will move forward when the knee is completely straight and as the knee bends past 30° the tibia shifts back into correct place in relation to the femur.
Indications for ACL Reconstruction
ACL tears are not always treated with surgery. The decision to undergo ACL reconstruction depends on several factors, including:
- Activity Level: Patients who engage in activities that require knee stability, such as sports, may be more inclined to undergo surgery to restore their knee's functionality.
- Age: Younger patients may be recommended for ACL reconstruction due to a longer expected lifetime of knee use.
- Severity of Tear: The extent of the ACL tear and its impact on the knee's stability play a significant role in the decision-making process.
- Lifestyle: Patients who desire a quick return to sports or an active lifestyle may opt for surgery.
- Associated Injuries: The presence of other injuries in the knee, such as meniscus tears or cartilage damage, can influence the decision to undergo ACL reconstruction.

Other Injuries Associated with ACL Tears
When an ACL tear occurs, it can often be accompanied by other injuries within the knee joint:
- Meniscus Tears: The menisci are cartilage structures in the knee that can also be injured during an ACL tear. Meniscus tears can cause pain, swelling, and limited range of motion.
- Cartilage Damage: : The articular cartilage, which covers the ends of the bones in the knee joint, can be damaged when the ACL tears. This can lead to joint pain and arthritis over time.
- Ligament Injuries: In addition to the ACL, other ligaments in the knee, such as the medial collateral ligament (MCL) or lateral collateral ligament (LCL), can be injured during a traumatic event.
- Bone Bruises: These are areas of bone damage that can occur during an ACL tear, causing additional pain and discomfort.
- Tendon Injuries: In some cases, the tendons around the knee may also be damaged.
Introduction to ACL Reconstruction Graft Options
ACL reconstruction is a surgical procedure in which a graft is used to replace the damaged or torn ACL. Grafts are usually harvested from either the patient's own body (autograft) or from a donor (allograft). Each graft type has its own advantages and disadvantages, which I will explain in detail below.
