Cruciate ligament injury is one of the most common injuries among athletes, as these ligaments play a major role in stabilizing the knee and controlling its movement. The injury often occurs due to a sudden sprain or wrong movement while running or jumping or a direct collision, which may lead to severe pain, rapid swelling, and difficulty walking. The seriousness of the injury depends on the extent of the tear in the ligament. It may be partial and can be treated with physical therapy or complete and requires surgical intervention to ensure the stability of the knee and restore its function naturally. With the advancement in treatment and rehabilitation techniques within Al Mousa Health Hospital, it has become possible for many

What is the cruciate ligament?

The anterior cruciate ligament is one of the main ligaments that stabilizes the knee joint and helps stabilize its movement. There are two types of it: the anterior cruciate ligament and the posterior cruciate ligament. As for the anterior cruciate ligament, it is located in the middle of the knee and connects the femur to the shin bone. It prevents excessive forward movement of the leg and maintains the stability of the joint. It is often exposed to injury when stopping suddenly or changing direction quickly during sports such as football and basketball.

As for the posterior cruciate ligament, it is less susceptible to injury. It is located behind the anterior ligament and prevents backward movement of the tibia and maintains the stability of the knee when it is bent. Injuries to it often occur due to strong shocks or car accidents. When either ligament is torn, the affected person may feel unstable in the knee and have difficulty walking, and may need physical therapy or surgical intervention depending on the severity of the injury.

Causes of cruciate ligament

The causes of cruciate ligament injury vary according to its type, whether it is anterior or posterior, and may occur due to sudden movements or strong shocks affecting the knee. Below we mention the most important causes in detail:

• Suddenly stopping or changing direction quickly, as happens in football, basketball, and tennis.
• Incorrect landing after jumping, where the wrong angle of the knee leads to excessive pressure on the ligament.
• Severe knee sprain due to abnormal movement.
• Direct physical contact, such as colliding with another player or being hit directly.

Causes of posterior cruciate ligament injury

• Car accidents where the force of the impact pushes the knee backwards.
• Direct falls on the bent knee, causing excessive pressure on the posterior ligament.
• Strong kicks or violent shocks, as occurs in combat sports or severe accidents.

Cruciate ligament symptoms

The symptoms depend on the severity of the tear and whether it is in the anterior or posterior cruciate ligament, but they are similar in some points. Below we mention the most important symptoms of the anterior and posterior cruciate ligament in more detail:

Symptoms of anterior cruciate ligament injury:

• Hear a clicking or popping sound when the rupture occurs. 
• Severe knee pain that appears immediately after the injury. 
• Rapid swelling within hours due to internal bleeding. 
• عدم استقرار الركبة والشعور بأنها لا تحمل الوزن بشكل طبيعي. 
• Difficulty moving or walking, especially when trying to turn or change direction. 

Symptoms of a posterior cruciate ligament injury:

• Pain in the back From the knee It increases when bent. 
• Gradual swelling that may not be as rapid as anterior. 
• Mild instability, but the injured person can walk with a feeling of discomfort. 
• Pain when trying to kneel or climb stairs. 

When is cruciate ligament surgery required?

It becomes necessary in some cases that cannot be treated with physical therapy or rehabilitative exercises. The need for surgery depends on several factors such as the level of sports activity, the severity of the tear, and the extent of its impact on the stability of the knee. Below we mention the most important reasons that make the operation necessary:

• If the tear is complete, the knee cannot regain stability without surgery.
• If the knee is clearly unstable and causes frequent falls or imbalance when walking.
• If the injured person is an athlete and wants to return to practicing sports, especially sports that require jumping or rapid rotation, such as football and basketball.
• If the injury is accompanied by a tear in the meniscus or other ligaments, which increases the weakness of the knee.
• If the patient does not improve with physical therapy after several months and the knee remains unstable or painful.

Tips to prevent cruciate ligament injury

The risk of injury can be reduced by following some preventive measures that increase knee stability and strengthen the surrounding muscles, which are as follows:

Strengthening the leg and thigh muscles

• Focus on strengthening exercises for your quadriceps and hamstrings to improve knee support.
• Practice balance exercises, such as standing on one leg, to increase movement control.
• Strengthening the hip and buttocks muscles because they help stabilize the knee during movement.

Improve the way you move and jump

• Learn how to land properly after a jump by bending the knee and hip rather than putting all the pressure on the knee.
• Avoid stopping suddenly or changing direction quickly without properly stabilizing your foot.
• Do exercises that help improve neuromuscular control, such as agility and balance exercises.

Avoid excessive fatigue

• Do not engage in vigorous exercise when feeling tired because the muscles are less able to protect the joint.
• Take sufficient rest periods during exercises to reduce pressure on the knee.

Wear appropriate shoes and equipment

• Use sports shoes that provide good foot support and reduce the risk of slipping.
• Wear knee braces if there is a previous history of injury or weak ligaments.

A good warm-up before exercise

• Do warm-up and muscle stretching exercises before any sporting activity to prepare the knee for movement.
• Focus on flexibility exercises to maintain normal movement in the joint.

Following these tips significantly reduces the risk of injury and keeps the knee stable during movement.

Frequently asked questions

How long does it take for the cruciate ligament to heal?

Recovery depends on the severity of the injury and the method of treatment. If the treatment is natural, it may take 6 to 9 months to restore the normal function of the knee. After surgery, full recovery may take 9 to 12 months with rehabilitation and exercises. Athletes may need a longer period before returning to sports at full performance.

Will the cruciate ligament return to what it was?

This depends on the severity of the injury and the treatment followed, as after surgery and intensive rehabilitation, the cruciate ligament can regain its function, but it will not return to 100% normal. Some people feel much better and return to sports, while others may suffer from slight weakness or roughness, so adherence to physical therapy is necessary to ensure a faster recovery.

Can the cruciate ligament be cured?

Yes, it is possible to heal, but that depends on the severity of the tear and the method of treatment in simple cases, where physical therapy can be relied upon to strengthen the muscles and support the knee, but in complete tears, surgery may be necessary with a rehabilitation period lasting several months to restore full movement and stability before returning to daily or sporting activities.

Can a cruciate ligament patient walk?

Yes, the injured person can walk, but that depends on the severity of the injury. In partial tears, walking may be possible with some pain and instability, but in complete tears, walking may become difficult, especially immediately after the injury. Swelling and pain may hinder movement, but with physical therapy or surgery, the ability to walk normally can be gradually restored.

Cruciate ligament injury is one of the problems that greatly affects the stability of the knee and a person’s ability to move. However, with the help of Al Mousa Health Hospital doctors, early diagnosis, and appropriate treatment, whether physical therapy or surgery, those affected can gradually restore knee functions and return to their normal lives. Commitment to rehabilitation exercises and taking preventive measures such as strengthening the muscles and improving movement style significantly reduces the risk of injury. Therefore, taking care of the knee and preventing excessive stress is necessary to maintain its health.
