Knee pain is a common complaint that affects people of all ages. Knee pain may be the result of an injury, such as a ruptured ligament or torn cartilage. Medical conditions such as arthritis, gout, pseudogout and infections can also cause knee pain. Whether we are talking about osteoarthritis, rheumatoid arthritis or any other form of arthritis, it is important to understand that big joints are almost always affected.
A knee injury can affect any of the ligaments, tendons or fluid-filled sacs (bursae) that surround your knee joint as well as the bones, cartilage and ligaments that form the joint itself.
Some of the more common knee injuries include:
- ACL injury
- Fractures
- Torn meniscus
- Knee bursitis
- Patellar tendinitis
Some examples of mechanical problems that can cause knee pain include:
- Loose body
- Iliotibial band syndrome
- Dislocated knee cap
- Hip or foot pain
