Yea, I would wait on the ortho and MRI results.
If it is indeed a meniscal tear and surgery is opted for, recovery will be dependent upon if you have a menisectomy or meniscal repair.
A menisectomy means that there is a tear and they go in and just clean it out. Generally, it is a 2-4 week recovery and progression into full activity. You can begin walking as soon as tolerated. I have worked with football players who get a menisectomy and are back playing on the field within 4 weeks post-op.
A meniscal repair means that there is a tear and they go in and suture it down. Generally, it is 4-6 weeks non-weight bearing post-op. Then you begin progressing into weight bearing activities, multidirectional movements, etc. Most people won't return to full function for about 2-3 months post-op.
Those time frames of return to full function is based from my experiences with athletes returning to full ability on an athletic field. People may return faster/slower depending on what they are returning to. Also, with the menisectomy, you are most likely to develop arthritis than you are with the meniscal repair.
Some doctors recently have been performing microfracture surgeries with certain meniscal situations. Depending on where they perform the microfracture, it can extend your return by upwards of 6-9 months or even a whole year.
