My endless thanks go to Dr. László Rudolf Hangody for the professional knee replacement operation. He has incredible experience and expertise and there was complete safety throughout the procedure. Anesthesiologist Dr. Réka Gilly and the operating theater nurse were a constant presence by my side. Hats off to the entire team of doctors, nurses and physiotherapists, who put all their efforts into my recovery with outstanding empathy. A particular surprise was the post-surgery pain, which was well within the limits of tolerance and lasted only a couple of hours, thanks to the anesthetic infusion. Since I struggle with a lot of illnesses, there were a few minor complications, but the team skillfully solved all challenges. I am very grateful to you all!
