Anterior cruciate ligament

Knees are joints that play a key role in performing many movements properly. Therefore, the problems that occur in the knees and cause pain are reflected negatively on the basic movements that we often do in our daily life, such as walking, running, collapsing, bending over, and getting up.

The knee joint consists of the femur (thigh), tibia (leg), and patella (kneecap). There are ligaments in different structures that connect these bones in the knee joint and hold them together. The anterior cruciate ligament is one of them.

As the name suggests, the anterior cruciate ligaments are located in the anterior part of the knee and cross in the middle. It restricts the rotational movement of the knee and ensures that it maintains its stable structure. It also reduces stress on the knee joint.


Ligament injuries usually occur in people who play sports. Anterior cruciate ligament rupture is one of the most common knee ligament injuries.

Sudden stopping, changing direction, turning movements cause stress on the knee and cause injury to the cruciate ligament and anterior cruciate ligament. Falling to the ground in an unbalanced manner after jumping or getting a direct blow to the knee also causes injury to the anterior cruciate ligament.

When it comes to cruciate ligament injuries, the first thing that comes to mind is football players. Because in football matches, players often make movements that may cause ligament injury. In addition to football, basketball, volleyball, skiing, tennis, gymnastics are also sports that can cause cruciate ligament injuries.

In anterior cruciate ligament injuries, the tissues may be partially or completely torn. Although the exact cause is unknown, anterior cruciate ligament injuries are more common in women who do sports.

WHAT ARE THE SYMPTOMS OF AN anterior cruciate ligament injury?

Injuries to the anterior cruciate ligament manifest with different symptoms.

  • Making a sound from the knee while moving,
  • knee swelling,
  • severe pain,
  • Numbness in the knee,
  • loss of movement,
  • Symptoms such as difficulty walking indicate anterior cruciate ligament injury.


People who experience one or more of the above symptoms should immediately consult an Orthopedics and Traumatology specialist. The doctor first performs a physical examination. After the knee is controlled by placing it in various positions with different methods (Lachman test, anterior drawer test, etc.), the level, nature and subsequent changes of the injury are determined by Magnetic Resonance (MR) imaging. X-rays are used to see if there are any problems such as a possible fracture or crack in the bone.

The treatment method in anterior cruciate ligament injuries varies according to the level of damage.

In non-surgical treatment, resting the knee, applying ice, bandaging, keeping the leg elevated with the help of a pillow help relieve swelling and relieve pain. In addition, thanks to physical therapy methods, the function of the knee is preserved by strengthening the muscles that support the knee.

The surgical treatment of anterior cruciate ligament injuries is performed with arthroscopic surgery, which is a closed method.

With the arthroscopy method, a small incision is entered into the knee and the structures here are examined. Thanks to the camera of the arthroscope device, the inside of the knee is enlarged and reflected on the monitor. The problem is detected and the torn ligaments are reconstructed. Rarely, ties can be sewn.
