Knee Pain FACTS

Symptoms of knee injury can include pain, swelling, and stiffness. Injuries are the most common cause of knee problems. Acute injuries may be caused by a direct blow to the knee or from abnormal twisting, bending the knee, or falling on the knee. Pain, bruising or swelling may be severe and develop within minutes of the injury. Nerves or blood vessels may be pinched or damaged during the injury. The knee or lower leg may feel numb, weak, cold. Acute injuries include sprains, strains, or other injuries to the ligaments and tendons that connect and support the kneecap.

Arthritis, Rheumatoid Arthritis, Post-Traumatic Arthritis, and Osteoarthritis can be a cause of severe knee pain and disability. This autoimmune disease causes the tissue around the joint to become inflamed and very painful. Treatment for a knee problem or injury may include first aid measures, rest, icing, bracing, physical therapy, medicine, and, in some cases, surgery.

Treatment depends on the location, type, and severity of the injury, as well as your age, health condition, and activity level at work, sports, or recreation hobbies.

What’s Inside My Knee?

Your knee is the largest joint in your body. A normal knee joint is made up of six components: the thighbone (femur), the shinbone (tibia), the kneecap (patella), tendons, ligaments and cartilage.

The lower leg consists of two bones: the tibia and the fibula, which act as anchors for the ligaments located on the outside of the knee joint. These ligaments - connect to the femur and help manage side-to-side knee movements.

Two additional ligaments inside the knee also connect the femur and the tibia; they control the forward and backward movement of the tibia, or lower leg, such as kicking straight ahead.

The patella is a triangular-shaped bone that most people think of as their kneecap. It sits at the front of the knee and is attached by tendons to the quadriceps muscles of the thigh. The patella allows the knee to straighten.

Both the femur and the tibia bone’s surfaces possess a smooth, durable cover of cartilage that acts as a cushion for the ends of the bones and enables them to move easily.

When all of these six parts work together in harmony, your knee joint moves easily and without pain.

Knee pain comes in many flavors.

Unfortunately, when one – or more – of the components that make up your knee get hurt or strained, you experience pain and malfunction in your knee.

Knee problems and injuries most often occur during sports or recreational activities, work-related tasks, or home projects. They can be caused by muscle strains, tendinitis, or more serious injuries to ligaments and cartilage. Severe knee pain can and often does limit your daily activities. Even mild chronic knee pain may challenge your everyday life.

Sports injuries to the knee can cause ligament sprains and tears, damage can occur to the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), and Medial Collateral Ligament (MCL). All of these knee injuries are very painful and may require surgery. Cartilage tears in the knee are another cause of knee pain.

Cartilage is a tough, but flexible tissue that covers the end of your bones. Two Menisci on either side of the joint are the Medial Meniscus, located on the inside of the knee, and the Lateral Meniscus positioned on the outside of the knee. When they become damaged, it’s commonly called a Meniscus Tear.

Those are just some of the many knee facts, you can learn more by asking your medical professional.
