Hi juhah,
Glad to hear the brace is helping with your pain issues, like you I have only 20% of meniscus left(lateral) and find my brace lets me do things I couldn't do cause of pain after walking distances, i'd started hiking again, until I reinjured my knee in dec'.
Sorry to hear your having nerve pain, it's a crappy pain to deal with,
Hope all goes well.
