You will have to give more information on where the tear is, how big is the tear? How did you do it? How bad does it hurt? What is your Range of motion? How long have you had the tear?
First of all a torn meniscus will never heal.It might lay down and be benign or it might keep lifting up and causing inflamation and pain.An MRI will give more information about the chances of recovering without surgery.If the tear is not large or a complete tear then there is a chance that the tear can lie down and not cause problems.If it is a large tear and is very symtomatic then surgery may be your only option.
