He competed for Ukraine's national team at the 2012 Summer Olympics in the Men's artistic team all-around and the Men's artistic individual all-around. The Ukrainian team, consisting of Kuksenkov, Igor Radivilov, Vitalii Nakonechnyi, Oleg Stepko and Oleg Verniaiev finished in 4th place in the team final. They were initially awarded 3rd position although a successful appeal from the Japanese team over one of their athletes scores resulted in Japan being promoted from 4th to 2nd place, displacing Ukraine from the medals. In the individual final Kuksenkov also finished in 4th position, again just missing out on a medal.
