She placed first in the short program — winning a small gold medal for the segment — eighth in the free skate, and fifth overall.

Later in 2010, Ovcharova underwent laser treatment on a small cyst in her leg but her condition only worsened.^[4][5] She was then diagnosed with two large cysts and incipient bone necrosis, leading to surgery in Geneva in 2011 and in Moscow in 2012.^[4]
