Simon was forced to miss the first live show of The X Factor as a result and had admitted that the terrifying fall had reminded him he isn't 'invincible'.
At the time, he was pictured being rushed to hospital while being stretchered out of his home in a neck brace.
After undergoing tests, he later returned to his home on the same day. He had been alone at the time of his fall, as his girlfriend Lauren Silverman was over in the US.
He later spoke about the fall and revealed he had fainted as a result of low blood pressure.

Speaking to The Sun, Cowell vowed to clean up his lifestyle for the sake of his young son Eric, three, whom he shares with Lauren. He claimed it was his 'responsibility' as a father to take care of his health.
'Sometimes we get a reminder that we're not invincible and this was certainly mine,' he said.
'It was a huge shock. They think I fainted because I had low blood pressure and so I have got to really take good care of myself to sort that out. After all I am a dad and have more responsibility than ever.'
Explaining how the fall had happened, he added: 'I'd gone to get some hot milk because I felt ropey. On the way back upstairs, I just remember feeling really dizzy.'

'Next thing I know someone was putting a neck brace on me and I had a terrible headache, which must have been from me hitting the stairs.'
'I was worried at first that I'd done some real damage. But I'm on the mend now. I know I was very lucky I didn't hurt myself seriously. It could have been a lot worse. I must say, everyone at the hospital were incredible. I'm truly grateful.'
The hunk has also made a drastic change in lifestyle after he ditched vodka from his diet, as well as making a conscious effort to severely cut down on the amount of cigarettes he smokes per day.
Speaking to Now magazine, the music mogul said: 'I've cut down smoking to two [cigarettes] a day. That's it!'
Cowell had been known to smoke up to 80 cigarettes a day and revealed he has now stuck to drinking just water.
