My name is HECTOR GONZALEZ, I have decided to make this comment in Spanish to tell my friends about my experience with the replacement of my knees (BOTH), Before deciding to have surgery I had a lot of pain like the problem of many, one day my Son suggested knee replacement to me. He told me that an American friend told him about his experience of knee replacement that his friend was super good! automatically pence, if he could, it looked good and changed his life !! why DONT YOU ASK ME? what if!!! I changed MY life TOO! from pain when walking to look GOOD! I honestly did not think twice, I looked for the same doctor who operated on my sons friend, El Khalid Mohammed Yousuf MD and I trusted the doctor now I can say that I am happy and I am not EXAGGERATING.I make and give this testimony conscious of my responsibility to tell and recommend it, particularly to friends, acquaintances AND TO ALL Hispanics who sometimes have certain fears, but as we are strong determined and when we find a doctor who puts his hands on our God, it is worthy of trust.Thanks to my doctor Yousuf who operated and replaced my two knees, one on October 30, 2020 and the other on November 4 a month later, then the therapy is hard but everything is possible, today is February 28 of the 2021, 5 and 4 months later, TODAY I am on my way, I climb stairs, there is no pain!I still need but it is the least! soon I will be totally fine, I can even RUN! Thank you doctor YOUSUF. AND THANKS TO ALL THE SUPPORT STAFF.
