Knee collateral ligament injury

Brief introduction of knee collateral ligament injury The knee collateral ligament injury is caused by a direct injury or a sudden fall in the knee flexion position. Part of the light injury, severely broken, or accompanied by meniscus, or cruciate ligament injury. If not treated promptly, it will seriously affect joint function. The disease generally has a history of obvious trauma. When you are injured, you can hear the sound of ligament rupture. Soon, you can't continue to exercise or work due to severe pain. There is local pain, swelling, and sometimes ecchymosis on the knee injury side. The knee joint cannot be fully extended. The disease generally has a history of obvious trauma. When you are injured, you can hear the sound of ligament rupture. It can not continue to exercise or work due to severe pain. Local pain, swelling, sometimes ecchymosis, knee joint Can not be completely extended, ligament injury at the site of tenderness, the medial collateral ligament injury, tender point often in the femur or the lower edge of the humerus; when the lateral ligament is injured, the tender point in the femoral epicondyle or humeral head At the office. basic knowledge Sickness ratio: 0.0001% Susceptible people: no specific population Mode of infection: non-infectious Complications: knee joint meniscus injury

Causes of knee collateral ligament injury

Cause (85%):

The knee is straight, the knee or the outside of the leg is subjected to strong violent blows or heavy pressure, causing the knee to be excessively abducted, and the medial collateral ligament may be partially or completely broken. On the contrary, the knee or the inside of the leg is subjected to violence or heavy pressure, so that the knee Excessive adduction, partial or complete rupture of the lateral collateral ligament, in the case of severe trauma, the collateral ligament, cruciate ligament and meniscus can be damaged at the same time.

Medial collateral ligament injury: caused by valgus valgus.

Lateral collateral ligament injury: mainly caused by knee varus violence.

Prevention of knee collateral ligament injury

First, do warm-up activities before the exercise, so that the joints heat up first.

Second, do not exercise under fatigue, so the reaction is slow, and the movement is not easy to coordinate.

Third, strengthen the exercises of lower limb strength to ensure the stability and flexibility of the knee joint.

Fourth, in sports, it is necessary to prevent accidental damage caused by rough movements.

Fifth, pay attention to the warmth of the knee joint, and the hot compress and massage of the knee joint can be performed regularly every day.

Sixth, avoid excessive fatigue of the knee joint, try not to do the knee joint squat exercise.

Seventh, those who are too obese should lose weight.

Eighth, avoid overload when exercising.

Complications of knee collateral ligament injury Complications knee meniscus injury

The structure of the knee joint is complicated and the trauma is many. The damage is mostly combined injury. In particular, the complication of the collateral ligament injury is more than 73%, and the damage of the III injury combined with other structures is about 100%. Common injuries There are anterior cruciate ligament injury, posterior cruciate ligament injury, meniscus injury, bone contusion, fracture, joint effusion, soft tissue around the knee joint.

Knee joint collateral ligament injury symptoms Common symptoms Knee joint pain Knee joint swelling Blood stasis Knee joint can not fully extend Joint pain Severe pain Macular ligament rupture

The disease generally has a history of obvious trauma. When you are injured, you can hear the sound of ligament rupture. It can not continue to exercise or work due to severe pain. Local pain, swelling, sometimes ecchymosis, knee joint Can not be completely extended, ligament injury at the site of tenderness, the medial collateral ligament injury, tender point often in the femur or the lower edge of the humerus; when the lateral ligament is injured, the tender point in the femoral epicondyle or humeral head At the office.

Examination of knee collateral ligament injury

The auxiliary examinations of this disease mainly include the following:

1. X-ray examination: Under local anesthesia, straighten the knee joint, according to the above inspection method, force the knee to receive or abduct, take a positive X-ray film, if the lateral collateral ligament is completely broken, the injured lateral joint gap increases. width.

2. Magnetic resonance: The anterior and posterior cruciate ligaments can be clearly displayed, and unexpected ligament structural damage and hidden fracture lines can be found.

3. Arthroscopy: It is very important to diagnose the cruciate ligament injury.

4. Special inspection

(1) Lateral pressure test (separation test): The knee joint is straightened, the examiner holds the injured limb in one hand, and the large fish in the other palm rests on the inner side or the outer side of the lap, and strongly receives or abducts the calf. If the medial collateral ligament is partially damaged, the abduction may cause pain due to the ligament involved in the injury. If the fracture is completely broken, there is abnormal abduction activity. Conversely, if the lateral collateral ligament is partially damaged, the ligament caused by the injury may cause pain during adduction; If it is completely broken, there is abnormal adduction activity.

(2) Drawer test: an increase in forward movement indicates a rupture of the anterior cruciate ligament, and an increase in posterior ligament fracture indicates a fracture of the posterior cruciate ligament, which should be compared with the contralateral side

(3) Axial shift test: A positive result indicates a fracture of the anterior cruciate ligament.

Diagnosis and diagnosis of knee collateral ligament injury

In the differential diagnosis, the disease needs to be identified with the following two diseases:

Medial collateral ligament injury

The important person responsible for connecting the thigh bone and the tibia in the inner side of the knee and preventing the left and right separation of the knee, that is, the medial collateral ligament, in addition to the lateral stability of the knee joint, also has the function of fixing the meniscus and controlling the knee joint activity. The ligaments, often subjected to external forces or excessive torsion on the outside of the knee, are extremely vulnerable, such as: skating, casual sprains or rugby, football, scrimmage, etc., and the collateral ligament is easily injured. When the medial collateral ligament is injured, the inner side of the knee will be swollen and painful. When the rupture of the medial collateral ligament is lightly pressed, it will feel pain. If the injury is serious, the knee will lack a sense of stability and will be unstable. Sometimes there will be Blood accumulation, when the collateral ligament is injured, the affected part can be lifted to a higher part than the heart, and the affected area is lightly applied with a cold damp cloth to minimize swelling. If the symptoms are mild, the affected part can be used to stretch the affected part. Fix it, first use cold and damp cloth and then use warm damp cloth method. After two to three weeks of local fixation, make the knee flexion and flexion of the thigh muscles in the range where the affected part does not hurt. Job training, if the situation ligament complete rupture, they have to receive specialized doctors surgery, suture the ligament rupture, whether minor or serious injury when the accident exercise, do not forget to add knee and other equipment.

2. Upper humeral protrusion

The part of the thighs that are responsible for the extension of the knee joint, the pain of the knee ligament to the attachment of the tibia, is the symptom of the disease, usually caused by excessive pressure on the knee caused by frog jumping, etc. It is the growth of the bone that is not as good as the muscle or tendon. The growing adolescents often occur. Because the ligament is tightened, the humerus of the upper part of the front tibia protrudes, and the bulge of the bone can be seen. When the hand is pressed, it will be dull. Like a sports knee, it is caused by unrestrained running or jumping, and people with o or X-legs are also considered to have a heavier burden on their knees than normal people, so it is easy to get this condition, with one hand against the wall. To support the body, the other hand grabs the same foot and pulls back, pulling the force of the knee joint that is pulled backwards by the flexion, so that the training of the thighs can be prevented.
