Anonymous users2024-02-13Meniscus injury is mostly caused by torsional external force, when one leg is weight-bearing, the lower leg is fixed in semi-flexion, and when the outer booth is located, the body and femur are suddenly rotated inward, and the medial meniscus is between the femoral condyle and the tibia, which is subjected to rotational pressure, resulting in meniscus tear. The greater the degree of flexion of the knee joint during sprain, the posterior part of the tear, the mechanism of lateral meniscus injury is the same, but the direction of the force is opposite, and the ruptured meniscus partially slides into the joints, causing mechanical obstacles to joint movement, hindering joint extension and flexion, and forming a "lock".
Meniscus injuries can occur in the anterior, posterior, middle, or marginal parts of the meniscus. Injuries can be transverse, longitudinal, horizontal, or irregularly shaped, or even broken into intra-articular loose bodies. The categories are:
Edge tears, transverse tears, longitudinal tears, horizontal tears, and anterior and posterior corner tears. In severe trauma cases, the meniscus, cruciate ligament, and collateral ligaments can be injured at the same time.
After a meniscus injury, the knee joint has severe pain, cannot be straightened on its own, and the joint swells. Tenderness in the knee space is an important basis for meniscal injury.
The young can be fully bred through **** very soon.

Anonymous users2024-02-12The greater the degree of knee flexion in a sports sprain, the posterior the tear. The mechanism of lateral meniscus injury is the same, but the direction of the force is reversed. If the ruptured meniscus partially slides between the joints, the joint movement is mechanically impaired, which hinders the extension and flexion of the joint, resulting in meniscus injury.
A clear history of knee sprain, after the injury, there is severe pain in the knee joint, walking may be accompanied by a snapping sound, can not be straightened spontaneously, and the joint is swollen. Tenderness in the knee space is an important basis for meniscal injury.

Anonymous users2024-02-10The causes of meniscus injuries can be broadly divided into two categories, one is caused by trauma and the other is caused by degenerative changes. The former is often caused by acute injuries and violence to the knee joint. The knee joint is strongly vargus or inward, internally or externally rotated during flexion, and the upper part of the meniscus moves more with the femoral condyle, and the rotational frictional shear force is formed between the lower part of the knee and the tibial plateau.
When the force of the sudden action is very large, and the rotational crushing force exceeds the allowable range of motion of the meniscus, it can cause meniscus injury. Meniscus injuries due to degenerative changes may occur without a history of significant acute injury and are usually caused by laceration due to the need to work in a semi-squatting or squatting position, long-term repetitive knee flexion, rotation, and straightening, and multiple crushing and abrasion of the meniscus.

Anonymous users2024-02-081.Meniscus injury is a disease characterized by localized pain in the knee joint, soft legs or locking of the knee joint, quadriceps atrophy, and localized tenderness of knee joint space fixation. If there is significant fluid accumulation in the joint, the fluid should be withdrawn.
If non-surgical treatment is ineffective, symptoms and signs are obvious, and the diagnosis is clear, the injured meniscus should be removed with surgery as soon as possible.
2.This is a kind of soft tissue injury, people have a certain misunderstanding of soft tissue injury, thinking that it is not serious, in fact, it is not, "100 days of injury and bones", this "tendon" is soft tissue, because there is no clear treatment method for soft tissue injury, and people lack of understanding, so it takes a long time to recover.
Advice: Rest more and reduce joint activity. Hot compresses can be applied to the injured area, followed by knee bone massage cream for anti-inflammatory and analgesic treatment, and then hot compresses to promote the absorption of voltarin. The most important treatment is rest!
Meniscus injury of the knee is the injury of two half-moon-shaped cartilage plates in the knee joint to maintain the normal stability of the knee joint and cushion the impact of the knee joint movement. This can be an acute trauma, especially a sprain, or an injury that occurs after a chronic strain. >>>More

I injured myself playing basketball about two years ago, and I felt very painful at the time, but after a few days of recuperation, my symptoms improved, and I have been dragging it out. During this period, the injured left knee could not be fully straightened, and could not do explosive movements with all his strength, and he would have pain after every exercise. About a year later, sometimes the joint will be locked after bending, and it will make a loud noise after the pain is straightened, so I went to 301 Hospital for treatment a year after the injury, and after the MRI examination, the doctor said that it was a posterior corner injury on the lateral side of the left knee and asked for surgery, but he didn't explain it to me carefully, so in order not to operate, I went to the Third Hospital of Beijing Medical University, because it is the most authoritative place in sports medicine in the country, and I hope they can have a conservative method. >>>More
Lying down and straightening your legs and raising your legs are effective, and I haven't tried squatting yet. You are almost as injured as me, and I also tied a 5-pound sandbag to my calf, and exercised my muscles dozens of times a day to prevent atrophy. I started to resume exercise yesterday, and I didn't move much for a month before, and I took some blood-activating medicine and hot compresses. >>>More
Second-degree meniscus injuries are moderate, not the most severe, but relatively severe compared to mild. At this time, there may be local swelling and pain in the knee joint, and there may even be some fluid or blood accumulation in the joint cavity, which may be inconvenient when walking, and even a feeling of jamming when walking, so it is still necessary to do something after the examination to determine whether it is a second-degree injury before it may get better. First of all, you need to rest more, walk less and move less, especially not up and down the stairs, and at the same time pay attention to keeping warm, don't get cold, you can do local hot compresses, you can use hot towels or hot water bottles, you can also go to the hospital to do some baking lights, physiotherapy and other physical **, and then oral medicine can be appropriate to eat some glucosamine and blood circulation pain capsules and other drugs, through these ** treatment of uncomfortable symptoms caused by the injury, it is possible to slowly improve and recover well, so as not to affect the function.
