I am a physician and a previous pro volleyball player with 6 knee surgeries involving meniscus tears/ repairs and Acl replacement.
I keep this very short. Look at your MRI report as the simple peripheral tears of the meniscus where blood supply is adequate may heal over months with rehab and lifestyle modifications. If the tear is complex and central where blood supply is poor then you need intervention with procedures. I highly recommend you to look in to blood cells injections in to the joint to promote healing of the tear. There are ortho centers that do that. Takes less than half hour office visit and you are done to continue with your day. Blood cells have ability to heal minor tears with fibrocartilage production. You may need injection once a week for a few weeks in a row and each time you will feel some improvement. For some surgery is avoided with healing of tears. My knee is arthritic and I keep a very active life despite my aweful looking mri and xrays with blood injections in to my right knee.
If you decide on surgery please make sure you do your search for the best ortho at a center with good records. It is an easy procedure with potential bad out come in a hand of a surgeon that is not meticulous or in a center that allows residents in training do the surgery with supervision.
Best of luck to you!
