Torn Miniscus --- Help!?

i tore my miniscus in my knee about 3 months back, maybe 4. for about 2 and a half months it was in pain constantly stiffening and inhibiting my movement. I Was advised to get a key-hole opperation on it if it was bothering me. However in the last month its sort of disappeared. No more pain or agility problems. However does this mean its healed itself or could it be slightly healed leaving me prone to a relapse in the near future?
