Long story short,..tore the meniscus on my right knee about 6 years ago. Had it operated on. It's been decent since then.
Last night I stood up from a low chair and it went *POP!*,....hurt pretty bad. No bones seem to be broken. It's not swollen. It's just stiff and painful today.
Any ideas what it could be?
A loose piece of meniscus found its way into the joint. I have had it happen. It will about buckle you sometimes.
