What Causes Joint Crepitus?

Knee Injuries

Sometimes, common knee injuries will cause an increase in the sounds of popping and cracking that occurs when individuals crouch or sit. Tears in the meniscus, scar tissue, or tendons passing over a bone fragment left after an injury can cause an increase in crunching or cracking sounds. After surgery for knee injuries, individuals often experience an increase in sounds, but these generally resolve after a short time. Patients who experience pain or swelling in the knee, along with joint crepitus, should make an appointment with an orthopedic specialist as soon as possible for diagnosis and treatment.
