Dr. Blatz performed knee replacement surgery on my left knee five years ago (at age 59), and I continue to be amazed at the mobility, durability, and pain-free use of knee. I would never know that the knee had been replaced if it were not for the almost invisible scar at the outer curve of the knee area. My healing was very speedy and successful, and even the physical therapists who worked with me were very impressed by the range of motion I had almost immediately after surgery. I have recommended Dr. Blatz to several friends, and will continue to do so.
