āThis injury couldāve ended any chance I ever had to be a professional athlete. Most people donāt know this injury has bothered me my entire career. I dislocated the same kneecap right after the 2012 Olympics where I won the silver medal in the 800-m race and had to call off my season right after. My right leg is weaker than my left leg. Since the day I was released from the hospital to this very day, I have a very distinct hitch when I walk. I wouldnāt say Iām limping, exactly, but you can see that thereās something unique about my gait. Itās not me trying to be cool.
