The knee is a joint that allows for the motion of your leg, by bending and extending. It is essential for sitting, walking and running.
Loose bodies inside the knee are often fragments of bone and cartilage that have broken off during an injury or have formed because of long standing arthritis. These loose bodies can float freely between the thighbone and shinbone, and may sometimes wedge into the joint. When this happens the knee may lock, causing pain or the feeling that it is going to give out.
Many of these problems can be treated through
• Activity changes
• Steroid injections or
• Physical therapy.
If these methods don't help, the doctor may recommend a knee arthroscopy. The knee arthroscopy is used to remove the loose fragments. This procedure lets the doctor look at the inside of the knee joint using a specialized camera called an arthroscope. The doctor will also be able to take out any loose fragments, which might be causing problems. Because a knee arthroscopy is an elective surgery, there are no serious or life-threatening consequences associated with not having it.
