A large number of people all over the world suffer from knee pain on a daily basis. These people usually find walking or climbing stairs very difficult which greatly limits their mobility in performing daily tasks. Usually, older people experience knee pain since their knees become weak after years of wear and tear.
Nonetheless, younger people or adults can still have the same conditions since knee pain causes can have many sources. Normally, people use their knees for a variety of movements such as running, climbing, and crawling.
As years pass by, the knees eventually weaken due to normal wear and tear but other knee pain causes can also make the situation more painful. It would be valuable to understand that the knee is a hinge joint formed by two bones- the femur and tibia. There are four important ligaments that hold the knees together which are surrounded by synovium. The synovium is a thick fluid that protects the cartilage. Similarly, the outer layer of the synovium also offers protection and support to the joint. A total understanding of the knee’s anatomy is beneficial in understanding the following knee pain causes.
Rheumatoid arthritis -One of the common knee pain causes experienced by the elderly. This condition happens when the body’s own immune system attacks its own joints.
The white blood cells accumulate in the synovium causing inflammation. This leads to redness, swelling, and pain usually first thing in the morning. As the condition worsens, the cartilage becomes eroded which can really be debilitating.
Osteoarthritis One of the main leading culprit of knee pain causes. Due to the breakdown of cartilage, the bones begin to rub together which can be really painful.
The result is inflammation and loss of movement. There’s also the likelihood of having a bone deformity later as time progresses. Small bone spurs begin to show along joint edges which is one of the painful knee causes in this condition.
The given conditions are just some of the common knee pain causes but there are other sources of knee pain too. The knee pain causes can be a symptom of something more serious depending on the pain’s location in the knee.
Other possible knee pain causes can be bursitis, softening of the patella or Baker’s cysts. Previous injuries or infections can also be knee pain causes that must be attended by a medical specialist.
