Is Surgery Effective For Tear In Meniscus?

Hi i have knee injury i consulted doctor and he explained to me there is tear in meniscus. Its been 1 year. I was told to do regular muscle strengthning exercises..which i did for a month but then not followed anymore. I dont feel fully recovered there is some pain and little restriction to do my knee movements. I want to know whether this could be treated safely/completely with surgery??
