What are some treatments of crepitus?

Crepitus: Crepitus is just a term to describe a physical exam finding of bones or joints that are "noisy" when manipulated or palpated. Crepitus is not necessarily associated with a condition that warrants treatment, or can be treated.

See long answer: Crepitus usually refers to the "crunching" or "grinding" sound joints make. This noise is a result of cartilage damage and subsequent roughening. Knees are the most common joint involved. Ususally, treatments are aimed not at the noise itself, but at the underlying cause. The focus is usually on treating the cartilage damage and forming strategies to protect and even regenerate the cartilage.

Quad strengthening: Crepitus is caused by softening and fibrillation of the cartilage on the underside of the kneecap. If your kneecaps do not track well within the groove of your knee, then there are surgical treatments to re-align your kneecaps. Mostly, though, this can be treated with quad and hamstring strengthening and stretching as well as lots of knee motion, like cycling or elliptical.
