Up to 40% of back surgeries fail within two years. Repeat back surgery often fails as well. Often the best option is to avoid another surgery with a nonoperative option that offers relief with absolutely minimal risk.

Stem cell and exosome therapy may work exceptionally well for achieving relief when it comes to failed back surgery syndrome, known as FBSS. Patients with FBSS may have postlaminectomy syndrome and possibly adhesive arachnoiditis, or may just suffer from chronic back pain.
