Prevent cruciate ligament injury

- May 20, 2020-

There are two parts of basketball that are most likely to be injured, one is the ankle and the other is the knee. Usually focus on protecting these two parts, which can greatly reduce the chance of injury. Don't ignore the protection of the knee. The joints are very fragile and require careful care. Let's talk about two common knee injuries.

Cruciate ligament injury

The cruciate ligament is the main stable structure of the knee joint, so it is prone to injury when the knee joint is traumatized. A comprehensive understanding of the degree, location and complication of ligament injury, especially the timely diagnosis of anterior cruciate ligament (ACL) injury, will seriously affect patients Prognosis. Although high accuracy, arthroscopy is traumatic. MRI is an accurate and effective method for non-invasive evaluation of ligament injury. It has been used to diagnose knee ligament injury. There are anterior and posterior cruciate ligaments (also called cruciate ligaments) in the knee joint. The anterior cruciate ligament starts from the front of the intercondylar bulge of the tibia, and stops posteriorly, superiorly, and externally on the medial surface of the lateral femoral condyle. The posterior, anterior, upper, and inner ends of the bulge stop outside the medial malleolus. Whether the knee joint is straight or flexed, the anterior and posterior cruciate ligaments are all in tension. The anterior cruciate ligament prevents the tibia from moving forward, and the posterior cruciate ligament prevents the tibia After moving.


Violence can cause knee overextension or excessive abduction can cause anterior cruciate ligament injury. For example, when bending the knee, external force is applied to the femur from the front to the back, or external force hits the upper end of the tibia from the front to the back, which can cause the anterior cruciate ligament to rupture. Anterior dislocation of the knee joint is often caused by overextension, which will inevitably damage the anterior cruciate ligament. If it is caused by excessive abduction, medial collateral ligament rupture can occur at the same time, and anterior cruciate ligament injury combined with medial meniscus injury is also more common. When flexing the knee, the external force hits the upper end of the tibia from the front to the back, causing the tibia to shift excessively backward, which can cause damage to the posterior cruciate ligament and even posterior knee dislocation.

How to prevent:

1. Avoid or reduce the following movements, and strengthen muscle exercises around the knee joint;

2. Emergency stop or steering during exercise-standing firmly on the ground, legs turning in other directions such as football or basketball players to stop and change direction quickly;

3. Straight knee landing-the knee joint straightens to the ground, such as the skier landing after jumping or the gymnast vaulting horse landing;

4. When the knee joint is overextended, it will fall sideways-the leg will suddenly stop when the knee is overextended. For example, when a baseball player slides to the base laterally, the knee joint is subjected to additional force;

5. Rotation and sudden deceleration-Sudden deceleration and torsion of the foot cause excessive rotation of the knee joint, such as a sudden turn of a football or rugby player.

6. Correct landing techniques are important to prevent knee joint injuries. It is recommended that when the exercise falls on the ground, the front foot should touch the ground first, the knee joint should be bent, and the torso should lean forward slightly. Try to avoid lateral or front-to-back movements of the knee. Remember that the knee joint should not be twisted inwards when landing, and the impact force should be reduced as much as possible.

Knee osteoarthritis

Chronic strain: Long-term poor posture, heavy weight-bearing, excessive weight, causing knee soft tissue damage.

Obesity: Weight gain is directly proportional to the incidence of knee osteoarthritis. Obesity is also a factor that exacerbates the condition. Obesity weight loss can reduce the incidence of knee osteoarthritis.

Bone density: When the subchondral trabecular bone becomes thinner and stiff, its tolerance to pressure decreases, so the probability of osteoarthritis in osteoporosis patients increases.

Trauma and local pressure: frequent knee injuries, such as fractures, cartilage, and ligament injuries. In the abnormal state, if the joint is unstable after patella resection, when the joint is subjected to muscle imbalance and local pressure is added, degenerative changes of the cartilage will occur. Normal joints and activities will not appear osteoarthritis even after strenuous exercise.

Genetic factors: The joint involvement of different races is different, and gender also has an effect. This disease is more common in women.

How to prevent:

1. Maintain the correct standing and walking posture, avoid high and low shoulders, head forward, hunchback, knee hyperextension, etc .;

2. Weight control;

3. Strengthen the strength of the muscles around the knee.

Follow the following actions to exercise regularly to protect your knees from injuries.

1. Hold the wall with both hands, lift one leg, and move the hip joint

2. Multi-level hip bridge, two-legged ball

3. Jump twice with one foot, then save the motion for a while

4. Press the whole body weight on one leg, the other leg makes a stride movement, the upper body does not move

5. Use both hands to lift the ball over the head, cross and step, the speed is not fast but the range is larger

6. Use the elastic rope for sliding
