The win represented a huge breakthrough for Savchenko, who didn't place in 2002 or 2006 and settled for bronze in 2010 and 2014.
The 34-year-old Savchenko's dream of an elusive first gold at her fifth Winter Games had looked dashed after an unfortunate error by her French-born partner Massot - who only received German citizenship in November - in February 14's short program.
"We celebrated new year together and we said 2018 will be our year, and it became our year".
"We heard what the Germans did before us".
And finally now, in her fifth Olympics, Aliona Savchenko will be coming home from South Korea with the one thing she's been missing-Olympic gold!
They skated well. But the Germans were simply superb. We said: 'OK, good for them.
At the end of their performance they lay in each other's arms on the ice, before Massot bowed to his partner and they made their way to the "kiss and cry" corner, where the tears flowed when their score of 159.09 points flashed up, beating the world record they set of 157.25 at the Grand Prix Final in December.
Savchenko and Massot, who is a native of France and only gained German citizenship in November, had found themselves in fourth place following yesterday's short programme with 76.59 points.
"We were on the ice for the gold medal and we didn't give up", Massot added. But it was nice that we got it out on Olympic ice.
"We are so privileged and lucky to be doing what we are doing, but it's so sad that 17 people died in the United States", Scimeca-Knierim said. We still have the free program to come.' We did a gold medal program, we broke the record.
When the Russian pair's scores were read, Massot enveloped Savchenko in a big hug. "We have to show to everybody that this program is an Olympic program, a gold medal program'".
The Germans' long program was not only completely mistake-free, it was gorgeously executed in stunning fashion, the only free skate to move the audience at the Gangneung Ice Arena to their feet.
"I was positive after yesterday".
It was a career-defining move which on Thursday at the Pyeongchang Games was rewarded with Olympic glory, and their adopted homeland's first pairs title since 1932. The spectacular, four-revolution element is so hard that only a couple of other pairs tried it.
Knierim fell on both of their triple jumps, Scimeca-Knierim was shaky landing their throw triple flip, and the married couple was out of sync on their combination spin as they finished 15th.
Their electric free dance gave them a winning combined total of 235.90.
"Unfortunately, too many mistakes today", Scimeca-Knierim said. I was sick last night and this morning with a normal stomach bug. "And then everything happened as I had imagined it and it came true".
