Dr Dybala comes over as a very abrupt Dr but has a heart of gold. I nearly lost my leg due to a Bacterial infection after another Dr did an Arthroscopy. This destroyed the knee and muscles and Dr Dybala treated me for 8 months before he did my knee replacement late October last year. I am 62 and I have been walking without crutches since December 2016 already. He has a heart of gold and saved my life.
