What is an ACL injury?

The anterior cruciate ligament (ACL) is probably the most commonly injured ligament of the knee. In most cases, the ligament is injured by people participating in athletic activity. As sports have become an increasingly important part of day-to-day life over the past few decades, the number of ACL injuries has steadily increased. This injury has received a great deal of attention from orthopedic surgeons over the past 15 years, and very successful operations to reconstruct the torn ACL have been invented.

What are the levels of ACL injuries?

There are 3 Types of ACL Injuries:

  • First Degree: the fibers of the ACL ligament are stretched, but there is no tear in the fibers. There is a little tenderness and swelling. Weight bearing and walking are still possible. The knee does not feel unstable or give out during activity.
  • Second Degree: the fibers of the ACL ligament are partially torn. There is tenderness and moderate swelling. Walking feels uncomfortable, and you may need to limp. The joint may feel unstable or give out during activity. It is recommended that you consult your doctor for evaluation.
  • Third Degree: the fibers of the ACL ligament are completely torn and there is usually a lot of pain at the time of tear, but decreases as time passes. There may be some swelling or a lot of swelling. The ligament cannot hold the knee in place properly and the knee feels unstable and may give out and walking is usually difficult and may require the use of crutches. This type of injury requires a visit to the doctor and may require some degree of surgery.

A knee brace for ACL protection can be an effective treatment in some individuals, but in sporting individuals knee surgery for ACL reconstruction is usually indicated to restore knee joint stability and reduce the risk of developing knee arthritis in the long term. Following ACL surgery, physical therapy rehabilitation is very important.

You should wear a knee brace if you are looking to prevent injury, feel any constant mild pain or instability, are going back to sports and activities after an old injury, think you might have injured your knee, and post-surgery.

What are the most common knee injuries?

Anterior Cruciate Ligament Injuries - Sprain or rupture of the anterior cruciate ligament, often caused by twisting the knee or an impact to the side of the knee.

Articular Cartilage Problems of the Knee - Injured areas, called lesions, show up as tears or pot holes in the surface of the cartilage that lines the ends of the bones.

Collateral Ligament Injuries - An injury to these ligaments usually involves a significant force, such as a fall while skiing or a direct impact to the side of the leg.

Hamstring Injuries - Rupture or strain of the hamstring tendons as they insert into the back of the knee.

Iliotibial Band Syndrome - ITBS is an overuse problem that is often seen in bicyclists, runners, and long-distance walkers. It causes pain on the outside of the knee just above the joint.

Meniscal Injuries - In younger people, the meniscus is fairly tough and rubbery, and tears usually occur as a result of a forceful twisting injury. The meniscus grows weaker with age, and meniscal tears can occur in aging adults as the result of fairly minor injuries, even from the up-and-down motion of squatting.

OA Knee - OA is sometimes referred to as degenerative, or wear and tear, arthritis. OA commonly affects the knee joint.

Patellofemoral Problems - Alignment or overuse problems of the patella can lead to wear and tear of the cartilage behind the patella. This produces pain, weakness, and swelling of the knee joint.

Posterior Cruciate Ligament Injuries - The posterior cruciate ligament (PCL) is one of the less commonly injured ligaments of the knee. The most common way for the PCL alone to be injured is from a direct blow to the front of the knee while the knee is bent.
