The knee is one of the strongest, largest, and most important joints in the human body which joins your thigh bone (femur) to the top of your shin bone (tibia) and acts as a hinge. The function of the knee joint is essential to many daily activities such as walking, standing, running, and sitting. The knee joint, while supporting the body’s weight, allows for flexion and extension and lets the lower leg move relative to the thigh. The knee contains four ligaments which ACL (anterior cruciate ligament) is one of them located in the center of the knee toward the front which keeps your knee stable by preventing the knee from sliding or twisting abnormally when the leg is straight or slightly bent and even Keep the knee from being stretched or straightened beyond its normal limits. It also keeps the knee from bending sideways by supporting the knee ligaments.

What is ACL injury?


An ACL injury mostly happens during physical exercises and sports such as playing football, basketball, skiing or soccer. Most of the injuries happen when a sudden force hits your knee while your foot is firmly on the ground and your leg position is straight or slightly bent or it can happen during running by changing direction rapidly or jumping and landing. When an ACL injury occurs, you hear a pop in the knee or feel a popping sensation. So, your knee will swell and feel too much pain and can’t bear your weight. Women are more likely to have an ACL tear than men.

ACL rupture is a severe musculoskeletal injury that is common amongst sports enthusiasts.

ACL Surgery in Iran


ACL reconstruction is a common orthopedic surgery aimed at repairing or reconstructing a damaged or torn ACL by replacing a torn anterior cruciate ligament (ACL) in your knee. The procedure is usually performed by making small incisions in the knee and inserting instruments for surgery through these incisions. In some cases, the surgeon has to perform open surgery and cut a large incision in the knee.

1- Non-surgical treatment


This type of ACL treatment is more effective for patients who are older with less activity level. It is very important to know that a torn ACL can’t be healed with non-surgical options. There are 2 options for non-surgical including bracing and physical therapy.

2- Surgical treatment


Most cases of ACL injuries are tears that cannot be healed naturally or stitched together. So, the surgeon will recommend a surgery method. In surgical treatment, the ligament must be reconstructed and will be replaced with a tissue graft. The graft can be obtained from the patellar tendon that runs between the kneecap and the shinbone or from hamstring tendons at the back of the thigh. Another source for graft is the quadriceps tendon which runs from the kneecap into the thigh.

Cadaver graft, also known as allograft, is also a good source for the graft. You should discuss with your orthopedic surgeon the source of the graft to choose the best option for you, as there are advantages and disadvantages to all graft sources. The graft acts as a bridge for a new ligament growing on. In replacing the graft technique, the surgeon will drill two holes called “tunnels” above and below the knee joint and place screws to anchor the grafts to it.

The surgeon will make small incisions to rebuild an ACL with an arthroscope. This is also well known as arthroscopic surgery. This method is less invasive with less pain and the minimum spending time in the hospital and the recovery is fast and quick. However, the regrowth of the ligament takes time about six months or more after the surgery.

Things to know about ACL Surgery


ACL reconstruction is a relatively safe procedure, however, there are some potential risks and complications that might arise. The most common risks and complications are:

    • Infection
    • Numbness
    • Nerve or blood vessel injury
    • Blood clots
    • Loosening, stretching, scar tissue, or re-tear of the graft tendon, creating a need for a revision ACL surgery

The most important complication that rarely might happen after anterior cruciate ligament surgery is infection which can be a serious problem. If you notice any sign of infection such as swelling, severe pain, chills and fever, you must see your doctor. If the infection occurs inside the knee in the graft tendon, you may have to get the graft removed depending on your physical condition and in that case your body may not be able to fight the infection.

There are some other complications of ACL reconstruction including roof impingement, postoperative stiffness, tunnel widening due to cyst formation, iliotibial band friction syndrome and hardware failure.

It is very rare to experience re-rupture of the cruciate ligament after surgery as the used autografts are stronger than the original ACL. In rare cases, ACL surgery may fail which is caused by improper tension on the graft, suboptimal positioning of the graft or improper fixation of the graft.

You are recommended to follow the instructions of your surgeon carefully preventing post-op ACL surgery complications. Choosing an experienced and qualified orthopaedic surgeon is also a major factor to reduce the risk of developing complications after ACL reconstruction surgery.

The people who have a torn anterior cruciate ligament are candidates for surgery if non-surgical alternatives fail to provide the desired results. At first, you should visit an orthopaedist immediately after a knee injury in order to evaluate your knee and the severity of the ligament tear and may ask you undergo certain tests for this purpose. The orthopaedist might prescribe you some medications and physiotherapy if the ligament is not completely torn. Otherwise, he/she might recommend a surgical procedure.

Here, we have listed the best candidates for a torn ACL surgery as follows:

    • Adults who are active
    • Children whose growth plates are closed
    • People with symptoms of instability such as knee pain and knee buckling during physical activities
    • People who tried non-surgical ACL treatments such as physical therapy but didn’t get tangible results

There are three major factors to choose a country as a destination for health and treatment purposes including cost, effectiveness of the treatment and safety. These factors undoubtedly can affect decision making of each patient.
