Noise, noise, noise! I am often asked about the meaning of knee noise (“crepitus”), which can often be quite spectacular — surely the loudest joint in the body. But knee noise in the absence of any other clear signs (like pain) is usually uninterpretable. It does not correlate well with problems. So you can be in trouble ... silently. And you can be fine... noisily. Rule of thumb: crepitus is only of concern if you’re also in pain, and not necessarily even then.
