When MRI is done in patients who have had prior surgery, the major reason is to distinguish between scar tissue and new disk abnormalities. Scar tissue is typically treated conservatively with physical therapy and meds, while new disk ruptures, spinal stenosis, or abnormalities at a different level can be treated in a number of different ways, including surgery.

Surgery generally isn't performed for scar tissue, since it is difficult to separate the involved nerve root from the scarring, and it is likely to recur.

I came across a few articles on microsurgical treatment of scar tissue with injection of compounds that dissolve the scar, and I believe that some surgeons are experimenting with laser treatment of scarring, but I didn't keep any of the references.

It would be worthwhile to ask your doctor about treatment of scar tissue involving any nerve roots, as it can certainly cause significant symptoms.
