A knee joint pain is complicated and knee pain can be affect anyone. The anatomy of the knee is quite complex, being made up of four bones – the femur in the thigh, the tibia and fibula in the leg and the patella in the center of the joint – and a whole series of structures which have the task of protecting and make it more functional and stable. First cartilages, constituted by a special connective tissue, which by coating all surfaces particular bone have the task of reducing the internal friction, An identical purpose have the two menisci, medial and lateral, which work by bearings dampers. Then there is the capsule, a kind of fibrous sleeve that wraps around the entire joint and, below which there is the synovial membrane, which secretes a liquid lubricant. Finally, there are the four ligaments – medial, lateral, and anterior and posterior circulate – that further contribute to increased stability.
Well, it will seem counterintuitive, but the very presence of such a large number of anatomical structures ‘protective’ articulation makes this particularly susceptible to many disease processes, however, can be divided into two major classes: degenerative and traumatic nature. At the first class belong all those more or less serious alterations caused by repeated use or from muscle and knee joint imbalances that with time they go to wear out especially the cartilage, as in the case of arthritis or inflamed tendons, especially the patellar. Belong to the second menisci tears and distortions that go to involve ligaments. Recall that statistics in hand, in sports the knee is the joint most often affected by injuries.
Common Causes of Severe Knee Joint Pain
If the pain is felt in the front of the knee, it could be a patellar tendinitis or an injury to the crusader. Laterally and may be caused by problems within the medial meniscus or collateral ligament, laterally, but outside, an event already more rare, from a lesion of the lateral collateral ligament and the lateral meniscus. If you feel back pain may be caused by damage to the posterior circulate ligament. Indicative for the purposes of a diagnosis also occur in that time of the day or in response to events such as the pain occurs.
If in the morning, when you wake up and then tends to disappear is easy it is a cartilage degeneration, whereas if with the passage of time gets worse or comes after we have been sitting for a long time, we are likely in the presence of an inflammation of the tendons, in particular the patellar. If the pain is sharp and sudden, and coincides with a sudden movement, it is likely there has been a menisci tear. While we are almost certainly in the presence of osteoarthritis, especially if they are not so young, if we perceive it after being long-standing or climbing, for example, the stairs.
The sports physician or orthopedist for a correct diagnosis, which then must still be validated by magnetic resonance imaging, the only instrumental examination useful in providing clear information on the state of the soft tissues, it will need a series of information: knowing which was the movement that caused the injury, if the patient experienced a snap or a cracking sound, the time after which the knee is swollen, if the pain was felt immediately or later, if after the trauma knee has become unstable, in the sense that it was no longer able to withstand the body weight, or it is blocked, preventing movements of flexion and extension. In function of the answers, it will already be possible to determine the type of lesion and its severity. The rupture of the meniscus occurs mostly when the knee undergoes a rotation in trauma or in response to movements of hyperextension or hyper flexion.
Knee Joint Pain
The pain, the crunch, the bulge and the block are practically immediate. In case of distortion, which can only cover the damage to some fibers or a complete rupture of the ligaments, the symptoms are different depending on the ligament us structures involved. So, if it is to be injured the anterior circulate ligament in the time of the accident will be felt in addition to pain, a snap and the immediate feeling that the knee joint pain from standing out. Usually the payment is of some significance. A little pain and a little liquid to be traumatized if it is the posterior circulate. Pain and swelling in some cases even absent if the distortion is the medial collateral or to the side, but very defined is the feeling of instability of the joint that tends to escape outwards or inwards.
