This is a tough problem - once the IMF has been distorted, you will need something stronger to hold it in place and prevent recurrence. The thing I like to use most is Strattice, which has a lot more strength than Alloderm, and doesn't stretch over time, making it ideal. But, there are some others to consider, like Galaflex. Anyways, you need at least this internal sling/bra, and maybe even more.
