I had my left hip revised in November, and my right hip revised for a different reason in February. Both were complicated procedures that most orthopedic surgeons could not have done. Dr. Mathias Bostrom did both surgeries and both were extremely successful (life changing for me). He is outstanding. I was very impressed with all aspects of the hospital. The level of service on every level was outstanding. My experience with Hospital for Special Surgery was of the highest caliber.
