The Troublesome Knee Injuries

Recommend to others!

The knee is technically a joint, which means it sits between the areas where bones connect. It’s actually the largest joint in the body. Your knees provide stability and flexibility for your body and allow your legs to bend, swivel, and straighten. It is made up of the lower end of the thighbone (femur), which rotates on the upper end of the shinbone (tibia), and the knee cap (patella), which slides in a groove on the end of the femur.

Since the knee has multifarious structure and weight-bearing capacity, it is commonly the most injured joint. Statistics show that each year, more than 5.5 million people visit orthopedic surgeons for knee problems.

What Causes A Knee Injury?

There are many factors to consider in determining the real cause of knee injuries. It varies depending upon the activity of the person. Some people acquire knee injuries due to direct blows to the knee, but the most common cause is the twisting, stretching of the knee which tears the muscles, ligaments and other accessory structures within it.

Types of A Knee Injury

Although everyone is susceptible to having knee injury, athletes are the most common victims afflicted with it. Some of the most common knee injuries include the following:

-          Anterior Cruciate Ligament (ACL) Injury. This injury occurs when there is a rapid and abrupt changing of direction, and slowing down when running. Also, landing from a high jump can cause ACL injury.

-          Medial Collateral Ligament (MCL) Injury. Injury to the medial collateral ligament is usually caused by a direct blow or force coming from the outside of the knee.

-          Chrondromalacia. It causes knee tenderness, knee pain in front of the knee, and a grating sensation in the knee. It is usually worst after a prolonged period of rest or when getting out of a chair. The knee cartilage is affected probably from overuse, trauma and/or abnormal forces on the knee, such as a misaligned patella.

-          Tendonitis. It is the inflammation, irritation, and swelling of a tendon. It can occur as a result of injury, overuse, or with aging as the tendon loses elasticity.

-          Posterior Cruciate Ligament (PCL) Injury. It is caused by a forceful direct blow to the front of the knee or when a person commit a simple outbalance.

-          Torn Knee Cartilage. Refers to a torn meniscus which is tough, rubbery cartilage that is attached to the knee’s ligaments. It acts as a shock absorber.

-          Arthritis is the most common disease that affects bones in your knees. The cartilage in the knee gradually wears away, causing pain and swelling.

-          Lastly, Knee Fractures.  It is caused by a forceful blow to the knee which can be obtained during contact sports or fall. It involves knee pain and swelling.

The knee is a very important part of the body. It gives us leeway to do the things we love to do and also allowing us to have a gainful employment. Injury to this essential joint can lead to a disability which could be both acute and chronic. Thus, it is very crucial to be safe in every activity we engage with. And consult your health care provider whenever you feel that something is wrong with your knee.
