Knee pain is one of the most common types of joint pain, and many people will have at least one episode in their lifetime. It is a bothersome symptom that is not quickly relieved and sometimes requires urgent medical attention. But if you or any other member of your family suddenly experience knee pain, is there anything special you need to know? What is causing knee pain? What can you do about it?
What is knee pain?
As the name implies, knee pain is an ache and discomfort in one of the most highly mobile articulations of the lower limbs. The knee is composed of various parts. In this area, we have two different bones attached to each other: the lower end of the femur and the upper end of the tibia. The articulation that joins these bones is called a hinge synovial joint, and it is highly mobile, allowing for flexion, extension, medial rotation, and lateral rotation. Various ligaments cover the articulation, it is protected and stabilized by the patella, and there are many others inside the articulation called cruciate ligaments, which prevent dislocation of the tibia.
Knee pain is often associated with a traumatic event, but may also be caused by a systemic disease as in rheumatoid arthritis and systemic lupus erythematous. In any case, there are different types of knee pain for each diagnosis, and not all of them are felt the same way. For example, we can have knee pain in various parts of the articulation (anterior, posterior, or lateral knee pain). It can be felt near the skin or deep beneath the skin in the articulation, and it may or may not be associated with the movement of the articulation.
But is it dangerous? In most cases, knee pain is not dangerous, but we should look for the appropriate ways to diagnose and treat the causes in order to avoid complications.
