Bursitis and How it Affects the Knees

[hemasri]

Millions of people all over the world complain of knee pain, which can  Nerve Renew Review   be caused by any number of things, from injuries to infections to arthritis and more. Some conditions can be treated and healed in a matter of weeks, while others are chronic and give sufferers trouble for many years. Knee bursitis is a condition that is semi-chronic, because although it can be treated, it can come back easily.

The simplest explanation of bursitis is to begin at the beginning. A bursa is a sac that is closed, and filled with fluid. The bursa is a smooth surface that helps to reduce friction between the body's tissues, and the largest bursae (plural for bursa) are located in the shoulders, hips, elbows and knees. When the bursa becomes inflamed, which often happens following an injury to the joint, it is known as bursitis, and it can be really painful.

Knee bursitis is particularly painful. There are three bursae in the knee, and the most commonly-seen knee bursitis can be found in the prepatellar bursa, which is right over the kneecap. This can easily become inflamed, especially when one is in a kneeling position for long periods of time. The conditions known as "housemaid's knee", "roofer's knee" and "carpet layer's knee" are all actually knee bursitis. Depending on the severity of the bursitis, it can cause pain and swelling, but not nearly as much pain as arthritis. Patients often report that the knees are warm, red and tender, and many say they feel stiffness in the knee joints, as well as pain while moving.

The other two bursae in the knees do not seem to cause as many problems for people, but they should not be overlooked. The second bursa is called the infrapatellar bursa, and it is located just under the kneecap, and below the tendon that attaches the thigh muscle to the kneecap. Most injuries to this bursa involve jumping and are often referred to as "jumper's knee". The third bursa is the anserine bursa, and it is located on the lower inside of the knee. Inflammation to this bursa is often seen in middle-aged women, and symptoms include pain in the back of the knee, especially when climbing stairs. Also called anserine bursitis, this condition is also common in those who are overweight.
