Knee pain is a common symptom in individuals of all ages. However, if left untreated or undiagnosed, it can be a severe problem that can lead to lost work and reduced activity. The knee joint moves through three different planes of motion: flexion/extension, adduction/abduction, and internal/external rotation. Knee pain typically occurs due to an injury or underlying knee problem. It is vital for individuals experiencing knee pain, whether sharp and intermittent, dull and aching or locking up, to see a specialist in knee pain in Jacksonville before attempting self-treatment.
There are numerous causes of knee pain, and you can read about some of them below.
- Injury
Most knee problems can easily be traced back to a knee injury. The most common causes of knee injuries are sports-related, such as overuse or a hit from a skateboard to the side of the leg. Other times it is due to a fall on an outstretched hand, sudden twisting motion, and may also result from jumping down off a step or from a height. Car accidents can also cause knee injuries.
- Fractures
A fracture of the kneecap (patella) or one of its supporting structures can cause severe pain. This is mainly caused by a significant injury, such as that due to an auto accident. A direct hit, such as a hockey puck or football player’s knee, can also cause fractures.
- Overuse
Overuse is a common cause of knee pain. Many people who run, cycle, use a ski machine, or do similar aerobic activities spend many hours using the same muscles that support the knee joint. This can result in wearing out the cartilage at the end of the long bones near the common area and inflammation of the tendons surrounding the knee joint.
- Patellar Tendonitis
Patellar tendonitis is a common cause of knee pain in athletes (mainly teenaged athletes). Patellar tendonitis can be acute or chronic. Acute patellar tendonitis, also called “jumpers’ knee,” is an inflammation of the patellar tendon which attaches to the kneecap. This condition occurs due to over-exertion of the tendon, such as repetitive jumping. Chronic patellar tendonitis is an inflammation that occurs more gradually. It tends to be caused by a combination of factors, including weak or tight muscles surrounding the knee, previous or more severe knee injuries, poorly fitted shoes, and poor training techniques.
- Arthritis
Osteoarthritis is the most common form of arthritis and one that occurs as people age. It results from wear and tear on the cartilage, which lines the surfaces where your bones meet to form joints. Over time, this repeated rubbing causes the cartilage to become less smooth and sturdy, leading to pain and stiffness in your joints.
- Bursitis
Bursitis is another common form of knee pain. The bursa is fluid-filled sacs that surround the kneecap and attach to the tendon. If your kneecap rubs up against your femur, it can irritate the bursa leading to swelling, redness, and pain in the area.
In summary, knee pain is a common condition, but it comes from many different causes. However, some of the most common include bursitis, arthritis, and patellar tendonitis. Overuse, fractures, and injury can also cause knee pain.
