The main types of knee injuries and mitigation methods:

1. Knee meniscus injury

Person's knee is the largest of all the joints in the joints, the main force to bear weight, which consists of distal femur and the tibia component, which before the patella, in which there is "cushion" that is half board, surrounded by strong joint capsule, muscle and ligaments to protect the stability of the joints.

The knee to bear weight, the vertical stress, the complex play of human actions, such as swivel, on the toilet Dunqi actions and others are the lateral stress. If the force is too large, the knee joints of two menisci are vulnerable to damage, especially in the spin too easily occur when the meniscus tear.

Meniscus injury accompanied by joint capsule damage, because of blood circulation-rich, easy bleeding and forming blood clots in knee joint cavity, pain and swelling. Journey sprained knee pain is a common thing, as long as you can not worry about meniscus injury and swelling.

Meniscus is the cartilage, almost no blood supply, once the damage difficult to heal, is the formation of joint pain after injury causes. Surgical removal of the meniscus by arthroscopic technique to remove small pieces torn and tear bar is easily accepted and effective method. We should not immediately meniscus surgery, walking carefully to maintain a stable knee joints still activity. But sometimes a small sliver may be due to the road or walking on uneven posture inconsistent factors such as movement, stuck in the joint space somewhere, the immediate pain can not walk on the road, medically known as the "interlocking joints", by the activity or processing can also "unlock", the symptoms disappear as soon as snapping. Interlocking joints should be aware of this particular phenomenon. The patients experienced repeated experience tend to unlock their own, namely, lower limb muscles relaxed, gently swaying, and flexion and knee (flexion-rotation practices) in order to achieve ease.

2. Knee joint loose bodies

Interlocking joint damage caused not only by the soft and a half months, there is a reason is that the intra-articular loose bodies, its size is very small, in essence, is a small piece of cartilage due to trauma or degeneration of the reasons for falling down by the joint surface, is shaped like a pea-sized, non - ossification by X ray photo did not come out, occasionally palpable, spin but disappeared, channeling to flee to move quickly, it is also known as "joint mice", which also can be stuck in the joint space, the formation of interlocking repeated there has given rise to intra-articular effusion, because usually hurt, often overlooked. Symptoms and dealing with meniscus injury.

3. Chondromalacia patella

Knee pain is another common cause of chondromalacia patella. Patella is a knee in front of a round bone, but also an integral part of the knee joint, located inside and outside the distal femur in front of the intercondylar fossa, patellar cartilage surface associated with the back section. Knee flexion and extension activities, contact between the patella articular surface could play a pivot role in both the upper and lower patella ligaments connected straight knee, the quadriceps tendon driven backward extrusion patella femoral condyle, the role of stabilizing the knee.

Repeated knee sprain or unreasonable exercise posture can cause wear and tear of patellar articular surface, cartilage loss of luster and flexibility, some chondromalacia off, mobile patella is cause pain. Still capable to endure daily activities, but fatigue. Activities that lead to little more than knee pain. Patients are not familiar with medical knowledge, mistakenly thought it was all the kneecap softens, the actual lesions of patella cartilage softening. Walk too much or uneven roads can cause knee effusion, joint swelling, the road is difficult to predict. With timely and rest, to resume quickly. If you have to stay in business, catch up with the trip, can go to the hospital for intra-articular injection of disolonum to speed up the disappearance of the symptoms.

How should we do to prevent injury?

People down, when, 1) weight-bearing knee is always in a state of alternating knees, when a very unstable joint ligament relaxation, thanks to support with the maintenance, when the joint with a lateral displacement is very easy to damage support the band, resulting in a small segment of fiber cracking, capillary bleeding. Were as follows: medial or lateral knee pain, the following mountains when heavy. 2) when the knee joint instability, if the external force by the lateral or sliding, center of gravity can be a sprained knee, resulting in meniscus injury. Were as follows: intra-articular pain, flexion and extension activities can not be combined joint swelling caused by joint capsule damage.

Do not load too much, if you want to exercise, may be a small mounting climbing too fast not to assault, uniform effort.

The way of proper rest, half-hour to an hour is appropriate, and added water.

With knee pad, strengthen joint protection.

For the knee joint disease known as people who should not be too steep a mountain board or a big step down.

In short, the climbers do not forget to protect joints, so that it can better longer work.
