Often heard some outdoor friends complain about knee pain, said that after a self-torture did not want to leave a wounded root, and some said to be meniscus fracture, and some say is patellar softening. . . . God, scared, but also scared to death, here may briefly introduce the basic knowledge of knee protection and prevention and control methods, of course, the specific circumstances but also according to the individual's age, physical condition may not be generalized. The above is just a family opinion. We welcome everyone to correct, add, discuss, and talk about their own special experiences.
The main types of knee injuries and their mitigation methods:
1. Knee meniscus injury
The human knee is the joint with the largest area of ​​all joints, and it receives the main force of weight. It is composed of the lower end of the femur and the upper end of the humerus. The humerus is located in front of the knee, and there is a "cushion", that is, a meniscus, with a strong joint capsule and muscle around it. Ligaments guarantee the stability of the joints.
The body weight is the vertical stress that the knee joint bears. Complex body movements such as the rotation of the ball and the squat movement of the toilet are lateral stresses. If the force is too great, the two meniscuses of the knee joint are vulnerable to damage, especially meniscus tears are more likely to occur when the rotational force is too large.
Meniscal injury is accompanied by damage to the sac, which is accompanied by abundant blood circulation, which can easily cause bleeding and hemorrhage, pain, and swelling in the knee cavity. Knee sprain pain is a common occurrence during the journey. As long as it is not swollen, there is no need to worry about meniscus injury.
The meniscus is a cartilage tissue. There is almost no blood supply. Once the injury is difficult to heal, it is the cause of arthralgia after injury. Surgical removal of the meniscus, arthroscopic techniques to remove small tears and strip tears are easily accepted and effective methods. Meniscal injury does not require immediate surgery. Walking carefully to keep the knee stable, the joints can still be active. However, sometimes small lobes can move due to uneven walking or inconsistent postures, etc., stuck somewhere in the joint space. Immediate pain can't be done. Medically known as "joint locking," or through activities. The treatment can also be "unlocked" and the symptoms disappear as soon as a snap occurs. Should be aware of the special phenomenon of joint locking. Experienced patients tend to unlock themselves after many experiences, namely to relax the muscles of the lower extremities, gently shake and flexion and extension of the knee joint (flexion and rotation techniques) to achieve remission.
2. The free body of the knee
The interlocking of the joints is caused not only by the soft injury of the half moon, but also because of the free bodies in the joints. The volume is very small. The essence is that the small pieces of cartilage are detached from the face of the joint due to trauma or degeneration. The shape resembles the size of peas, not Ossification of the X-ray can not shine, occasionally touched, and I do not know whereabouts, I come and go quickly to move, it is also known as "knuckle rat", it can also be stuck in the joint space, forming a lock, repeated Occurrence of joint effusion caused by the emergence of the usual pain, often overlooked. Symptoms and treatment with the meniscus injury.
3. Tibial osteomalacia
Another common cause of knee pain is patellar softening. The sacrum is a round bone in front of the knee, which is also an integral part of the knee joint. It is located in front of the intercondylar fossa at the lower end of the femur, and the cartilaginous surface behind the sacrum is associated with it. Knee joint flexion and extension activities when the articular surface contact each other can play a fulcrum, the ligaments are connected to the upper and lower ligaments, when the knee joint straight, the quadriceps tendons move the patella compress the femoral condyle back to stabilize the role of the knee joint.
Repetitive sprains or unreasonable exercise postures of the knee joint can cause wear of the articular surface of the humerus. The cartilage loses its luster and elasticity. Some cartilage softens and falls. The movement of the humerus causes pain. Daily activities can still endure, but it is easy to fatigue. A little more activity leads to knee pain. The patient is unfamiliar with medical knowledge and mistakenly believes that the entire patella is softened. The actual lesion is cartilage softening of the patella. Excessive walking or uneven roads can cause knee joint effusions, joint swelling, and unpredictable travel. Just rest in time and recover quickly. If you must do as usual, catch up with the trip, you can go to the hospital to do intramuscular injection of prednisolone to accelerate the disappearance of symptoms.
How should we prevent damage?
When a person is going down, 1) The knee joint is always in a state of alternate knee flexion. At this time, the ligament-relaxed joint is unstable and is supported by the support belt. When the joint has a lateral displacement, it can easily damage the support belt. Fine fibrinous segments, capillary bleeding. The performance is: the inside or outside of the knee is painful; 2) When the knee joint is unstable, if it is affected by lateral force or sliding, the center of gravity is unstable, and the knee joint can be sprained, causing meniscus injury. The manifestations are: severe pain in the joints, failure to flexion and extension, joint swelling due to joint capsule injury.
Do not exercise too much weight. If you want to exercise, you can do it by climbing up.
Proper rest on the way, suitable for half an hour to an hour, and add water.
With knee pads to strengthen joint protection.
For those who are suffering from knee disease, it is not appropriate to climb a steep hill or step up and down.
In short, mountaineering does not forget to protect the joints, so that it can work better and longer.
