"I have had three procedures at HSS in 2013/14. Dr. Bostrom did an extraordinary knee arthroscopy and I have regained full knee range minus pain. Dr. Darren Lebl replaced discs in my back and neck. I am just amazed at his skill and technique, I barely have a scar! I went in with a terrible pain in my arm and shoulder, I had a scar on my neck from previous cervical surgery, and I could scarcely believe that all these issues were resolved."
