I had an amazing experience with at HSS. Dr Shubin Stein did my TTT (Tibia Tubrical Transfer) on both knees, each 6 months apart, and then screw removal. Both surgeries went way better than I could have imagined. Previously, I had crunching and significant pain especially with stairs. Now I never have pain and feel free to to whatever exercise I desire. Within a year after the first surgery, I ran a Mud Run obstacle 5K with no pain during or after. Not only was the doctor amazing, but her staff, particularly Amy and Maggie, were always available via email or phone calls to help with any questions and made sure I was well taken care of during and after surgery.
