Knee Ligament Injury: Causes, Symptoms, Treatment Options

Knee Ligament Injury: Causes, Symptoms, Treatment Options

1. What is knee ligament injury?

Knee ligament injury is one of the more common knee pain problems, which usually refers to the injury of one or more ligaments in the knee joint. The knee joint is a complex joint made up of the patella, femur, and tibia, and ligaments play an important role in connecting and stabilizing these bones. Common knee ligament injuries include: anterior cruciate ligament injury, posterior cruciate ligament injury, medial collateral ligament injury, lateral collateral ligament injury, and multiple ligament injuries.

Knee ligament injuries often cause pain, swelling, joint instability, and limited movement. Severe injuries may require surgical repair, while minor injuries can be managed with physical therapy and rehabilitation.

2. What are the common causes of knee ligament injuries?

There are many possible factors for knee ligament injury. Most patients’ knee ligament injuries are often caused by external factors. A small number of patients may suffer from knee ligament injuries due to genetic factors such as genes. Here are some common causes of knee ligament injuries:


1. Sports injuries: Participating in high-risk activities and outdoor sports, such as football, basketball, rugby, skiing, tennis, etc., can easily cause knee ligament injuries. These activities involve rapid twisting, jumping, and impacting of the knee joint, increasing the risk of ligament damage.


2. Accidental sprain: Sudden knee sprain or incorrect landing posture can cause knee ligament damage, which is common in skydiving, long jump and other sports.


3. Accidental fall: When an accidental fall occurs, the knee is severely impacted in a short period of time, causing ligament damage due to the imbalance of the knee.


4. Muscle imbalance: Weakened or unbalanced thigh muscles cannot provide stable strength support for the overall knee, which will increase the risk of knee ligament injury.


5. Prolonged overuse: Performing the same type of exercise or maintaining a single posture for a long time can cause excessive fatigue of the knee ligaments and cause injury.


6. Age factor: As we age, ligaments and soft tissues may gradually lose elasticity and tolerance, increasing the risk of injury.


7. Genetic factors: Personal genetic factors will affect the stability of knee ligaments to a certain extent. The knee ligaments of some special patients are easily damaged.

3. What are the common symptoms of knee ligament injury?

Different knee ligament injuries and the location of the injury can cause different symptoms. Here are some symptoms of common knee ligament injuries:


1. Persistent pain: Knee ligament injuries are usually accompanied by significant pain, which can vary depending on the severity of the injury. Pain may come on immediately after the injury or gradually worsen


2. Knee swelling: After the ligament is damaged, swelling will appear around the knee. Inflammation can lead to persistent edema in the knee and even effusion in the knee.


3. Knee instability: Damage to the ligaments in the knee can lead to a feeling of instability in the joint, which feels like the knee is struggling to support body weight. This can make walking, standing, and moving difficult.


4. Limited range of motion: Damage to the knee ligaments will cause the knee to bend and straighten unable to reach the normal state, and persistent pain will limit the range of motion of the patient’s knee.


5. Knee noise: After the ligament is damaged, the patient may hear a “creaking” sound from the knee, which is one of the signs of damage to the ligament and soft tissue.

4. How to diagnose knee ligament damage?

Accurate diagnosis of knee ligament damage helps to adopt correct and effective medical treatment plans. When you need to fill out a health insurance bill, the ICD-10 code for an accurate diagnosis of knee damage is the answer (by the way, the ICD-10 code for knee ligament damage is: M23.3 – Anterior cruciate ligament sprain and injuries, M23.2 – Posterior cruciate ligament sprains and injuries, M23.0 – Medial collateral ligament sprains and injuries, M23.1 – Lateral collateral ligament sprains and injuries)


1.X-ray inspection: one of the conventional radioactive inspection methods. X-rays are used to create images of the tissue, bone, and overall structure of the knee area on film to rule out bone-damaging effects on the knee.


2. Magnetic resonance imaging: using high-frequency magnets, radio frequency and computer to generate detailed images of knee tissues and bones, which are clearer and more accurate than X-ray imaging techniques. It can determine the specific damage state of the knee ligaments.


3. Knee arthroscopy: Arthroscopy is usually used for minimally invasive diagnosis and treatment of knee joint diseases. A small illuminated arthroscope is inserted into the incision in the knee joint to look inside the knee. Knee arthroscopy can effectively diagnose damage to the knee ligaments.

5. How should knee ligament damage be treated?

Different levels of knee ligament damage require different medical treatments. Mild knee ligament damage can be treated simply at home, while severe knee ligament damage requires timely medical treatment. Here are some common treatments for knee ligament injuries:

1. Adequate rest and protection: The first treatment step is to give the knee ligaments adequate rest to reduce the risk of further injury. Using crutches or knee braces can help take the load off your knees.

2. Ice and heat compress: Ice compresses can reduce swelling of emergency damaged knee ligaments and relieve the pain caused by ligament damage. A hot compress can accelerate blood flow in the knee and enhance the knee’s self-healing ability.

3. Use elastic bandages: The use of medical elastic bandages can ensure that the knee tissues and muscles remain in a stable state, and the knee ligaments can also recover better. But don’t be too tight so as not to affect blood circulation.

4. Drug treatment: Using non-steroidal anti-inflammatory drugs such as ibuprofen can reduce knee pain to a certain extent and eliminate inflammation.

5. Surgical treatment: Severe knee ligament injuries cannot be effectively solved by conventional physical and drug treatments. Knee repair surgery includes ligament repair and ligament reconstruction, allowing you to properly treat your severely damaged knee.

6. Chinese medicine therapy: Acupuncture and traditional Chinese medicine pain-relieving patches also have a good therapeutic effect on knee ligament injuries, but they cannot be applied to severe knee ligament injuries, such as ligament tear or ligament rupture.
