how much is still attached. I tore meniscus in right knee twice 20 years apart. Healed both times with PT exercises and being cautious about twisting or any motions to strain the knee joint. First one took 6-8 weeks second about the same. At now 76 my time memory is a little fuzzy, but all else is accurate. First one in my late 20's in car accident second in my late 40's stepping off an extension ladder.

First one, doctor said let's get you scheduled. 2nd opinion sent me to a PT and said if it is still painful in 4 weeks come back and see me. Second tear, doctor said let's get you scheduled. I asked what kind of tear and he said it looks like a Parrot tear. I said I'll think about it and went home and did the PT on my own same as first one and it healed.

Both times the pain was completely gone by around 3 weeks.

Asked the 2nd opinion doctor what was the worst thing that could happen. He replied it will move to where it locks up your knee and you will come right in so we can take care of it. Even arthroscopically I will damage your knee further and increase likelihood of arthritis later in life. Do the PT first before we enter the knew for repair.
I have no arthritis in my knee.
I also took supplements. Can't positively say how helpful they were, but the PT that recommended them to me was an NFL team PT for 8 years and they did that with all joint injuries. He swore it cut recovery/healing time even with surgery.

Everyone is different and your tear may be more severe than mine. This is just my personal experience.
