FAQ: In Orthopedics What Is Acl?

What exactly is your ACL?

“ ACL is short for anterior cruciate ligament, and it’s one of the major ligaments in your knee that connects the femur to the tibia or shinbone below,” explains Orthopedic Surgeon Scott R. Kling, M.D. “Since the ACL stabilizes your knee, when it’s torn, your knee can buckle.”

What does an ACL allow you to do?

The ACL prevents the tibia from sliding too far forward. The ACL also contributes stability to other movements at the joint including the angulation and rotation at the knee joint. The ACL performs these functions by attaching to the femur on one end, and to the tibia on the other.

What causes ACL injury?

An ACL injury often occurs during sports. The injury can happen when your foot is firmly planted on the ground and a sudden force hits your knee while your leg is straight or slightly bent. This can happen when you are changing direction rapidly, slowing down when running, or landing from a jump.

Can ACL heal itself?

The ACL cannot heal on its own because there is no blood supply to this ligament. Surgery is usually required for athletes because the ACL is needed in order to safely perform the sharp movements that are required in sports.

Is ACL injury painful?

A torn ACL is very painful and can debilitate a person for several months and perhaps for life, although recovery for some is possible.

Can you bend your knee with a torn ACL?

After you damage your ACL, it’s very likely that you won’t be able to bend and flex your knee like you normally would.

Is it bad to delay ACL surgery?

(Reuters Health) – For some people, delaying knee surgery after an ACL rupture and trying exercise therapy instead may produce better outcomes over the long term, researchers suggest.

Can you walk with a completely torn ACL?

Can you walk with a torn ACL? The short answer is yes. After the pain and swelling subsides and if there is no other injury to your knee, you may be able to walk in straight lines, go up and down stairs and even potentially jog in a straight line.

What happens if you don’t do ACL surgery?

If nothing is done, the ACL injury may turn into chronic ACL deficiency. Your knee may become more and more unstable and may give out more often. The abnormal sliding within the knee also can hurt cartilage. It can trap and damage the menisci in the knee and can also lead to early osteoarthritis.

Why is an ACL injury so bad?

This is attributed to several reasons, including differing hormone levels, different jumping and landing mechanics, and anatomical differences which can lead to an increased angle at the knee joint that yields sharper forces at the knee than in males athletes.

What happens if ACL injury is not treated?

Left untreated, an injury to the ligament can develop into a chronic ACL deficiency. When this happens, the ligament is unable to control and support knee movement. Increasing weakness and further damage can result without proper treatment.

Where is ACL pain located?

You will likely feel pain in the center of your knee during an ACL tear. Because the MCL is located on the side of your knee, the pain and swelling will be located on the inside of the knee structure rather than the middle.

Can ACL injury heal without surgery?

But full ACL tears cannot be healed without surgery. If your activities do not involve making pivoting movements on the knee, physical therapy rehabilitation may be all you need. Special exercises may help train the musculature around the knee to compensate for the torn ACL and stabilize the joint.
