If a mri says that i have a displaced medial meniscus does that mean i have a tear of the meniscus? i have been having painful clicking and catching

Yes: A displaced meniscus means there is a tear of the meniscus and a portion of the torn meniscus has moved away from its normal position. This is a common cause of clicking and catching.

Most likely, yes: A "displaced meniscu"s really means a displaced meniscus tear. Displacement cannot really happen without the meniscus having been torn. Usually the meniscus tears in the "white zone:, called so because it lacks a blood supply and therefore cannot heal. Occasional, ly , tears occur in the "red zone" and can be sewn together; time is of the essence in the repair of "red zone" tears.
