Question:
Is there something wrong with my knee?
When i get up sometimes after sitting on the floor and use my knee to help me get up it makes this weird cracking noise and I feel a bit of pain. What's wrong?
Answers:
The most common cause is a tendon rubbing against another tendon or ligament, says Robin Dore, M.D., a rheumatologist in private practice in Anaheim, California. When you're young and still growing, ligaments, tendons and bone may grow at different rates, so your adolescent child may sound like a tiny percussion section now and then. As you get older and the cartilage around your joints thins, the ligaments and tendons snap at you because they are rubbing against each other, Dr. Dore says.
If you're double-jointed, you have a slightly more interesting reason for the cracking: Your ligaments and tendons are longer and more elastic than normal, so the joints move farther than they should and crack more often. Most people normally outgrow being double-jointed by their mid to late twenties, however, Dr. Dore says.
Other than the rub of a ligament or tendon, the only other known cause of cracking is a nitrogen bubble that suddenly depressurizes in the tissues of your joint as you move. It's like a teeny-weeny case of the bends inside a joint, says Kent Pomeroy, M.D., a physiatrist in Scottsdale, Arizona.
