Common Knee Pain Causes

Common knee pain causes include the following:

Sprained or Strained Knee Ligaments and Muscles

A sprain is when the fibers in one of the ligaments have stretched or torn. This condition can be caused by sudden impact, putting too much weight or pressure on a knee, or a sudden twist that stretches a muscle, tendon, or ligament.

A strain is a tear that occurs in muscle fibers or the tendons. This condition may occur after a dramatic increase of activity, like walking for more in a day than you usually do. Symptoms often include pain, swelling, and difficulty in walking.

Torn Ligament or Cartilage

A knee tear is is an injury to one of the ligaments or layers of cartilage that supports and stabilizes the knee. A knee tear may be partial, in which some of the structure is damaged – or complete, in which a ligament or meniscus is torn in two or separates from the bone.


Tendonitis refers to the inflammation of tendons from overuse during activities such as running, jumping, or other sports.


Osteoarthritis is the most common type of arthritis that affects the knee. Osteoarthritis is a degenerative process where the cartilage in the joint gradually wears away. It often affects middle-aged and older people. Osteoarthritis may be caused by excess stress on the joint such as repeated injury or being overweight.

Rheumatoid arthritis can also affect the knees by causing the joint to become inflamed and by destroying the knee cartilage. Rheumatoid arthritis often affects persons at an earlier age than osteoarthritis.
