What Causes Knee Pain without Injury
Sometimes the cause of knee pain is obvious: a twist, misstep or strain can strike at any time during a walk or a run. Other times, patients suffer knee pain without injury, and are unsure of the source of their discomfort.
You’ll need to consult with a physician to determine the cause of your knee pain, but there are several common causes of knee pain without injury.
- Bursitis: Tiny sacs of fluid cushion the bones in the knee joint. When they become infected or irritated, they can become inflamed, leading to a condition known as bursitis. This painful condition may be accompanied by redness around the joint, tenderness at the knee and in some cases, fever.
- Tendinitis: Tendons are the tissue that binds muscle to bones, and tendinitis is common in the knee. It’s characterized by a dull ache in the knee that increases with use. It may become swollen or painful. In some cases, rest alone can combat tendinitis, but severe cases require medical intervention.
- Baker’s cyst: Also known as a popliteal cyst, a Baker’s cyst is a fluid-filled swelling at the back of the knee. Because of the swelling, it can restrict movement. It can be a sign of an undiagnosed knee injury. In many cases a popliteal cyst will go away of its own accord. Sometimes, fluid may need to be drained from the cyst.
- Osteoarthritis: Inflammation and swelling of the knee joint itself, this condition is caused by deterioration of the knee. It can be caused by past injury, poor posture or obesity.
- Rheumatoid arthritis: This autoimmune disease is similar to osteoarthritis, but is often not localized to a single joint, and is indicated by stiffness, swelling and pain.
Knee injuries don’t have to be dramatic or catastrophic, so there’s a chance that knee pain is caused by an undiagnosed injury such as damaged cartilage, a torn ligament or meniscus or dislocation.
Because there are many causes of knee pain without injury – sometimes, including a forgotten injury – it’s necessary to seek treatment with experienced doctors who can diagnose your condition. Call 303.772.1600 to schedule your consultation with Front Range Orthopedics and Spine today.
