Torn Medial Meniscus
I just recently tore my medial meniscus, an injury which is apparently quite rare for kids my age (12, within a week of 13), but as I just experienced a large growth spurt, (6 inches or so in the past 9 months), so apparently my chances were higher.
Now the issue is that I am banned from all activities strenuous on my knee (Fencing, Aikido, Soccer etc.) What can I do to keep myself limber? Does Aikido really affect my knees enough to be a problem? Is it possible that I tore it in Aikido?
Thanks in advance,
