“A little bit sore and a little bit stiff but that is to be expected,” Langton said of his condition.
“I can’t really complain too much.”
The teenager did not receive his medal until he returned to the team hotel on Saturday evening, with the other members of the team gathering to applaud him.
Whitehouse said the team wanted to do that in order to replace videos of his fall, which were circulating widely on social media over the weekend, with something more positive.
“That was incredible,” Langton said of the moment.
“Seeing all of the team-mates, coaches and getting my medal. I saw my personal coach from Birmingham. It was so nice.”
These things are, of course, relative, but Whitehouse’s Sunday was a disappointing one. He came seventh in an all-round final won by Scotland’s Reuben Ward.
His response on Monday was almost immaculate.
Malaysia’s Muhammad Sharul Aimy, Australia’s James Hardy and Ward all made mistakes in the early rounds of the competition, giving Whitehouse – the fifth gymnast to enter – an opportunity.
He barely faltered, scoring 14.566 to take gold – a score that was not bettered by the remaining three competitors.
“The last few days have been about regrouping after everything that’s happened and then coming out and delivering a good performance,” he said.
There was a similar story later in the women’s vault when England’s Abigail Martin, who finished 11th in the women’s all-round final, took silver behind Canada’s Lia-Monica Fontaine.
“Yesterday didn’t really go to plan the way I wanted it to, but I’m really pleased that I managed to pick myself back up today,” Martin said.
“For me, I just had a little cry about it, but then I thought about all the things that had gone well.”
Whitehouse and Martin will be back on Tuesday in the vault and floor respectively. Langton will again be in the stands.
He plans to “take it easy for a couple of days and do the rehab” before returning to training in the near future.
“I trust in my gymnastics capability,” Langton said.
“It was really just a freak accident.”
