In an new interview on the TODAY show, Khloe opens up about the moment she got that phone call and how difficult it was having to make life or death medical decisions for someone she cares so deeply about.
"They told me that he had four hours - it's a horrible call to get. It's terrifying," she told them. "You have to make risk and reward decisions - like 'there is an 80% chance if we do this operation, he might pass away, but also if we don't do it, there is a 90% chance he'll pass away.' Just having to make these executive decisions is really hard on anybody."
She describes it as one of the 'most emotionally stressful times' ever in her life, which is completely understandable.
As for his current status, Khloe says that every day is different. "He's OK," she said. "He is learning how to walk again and how to do therapy and speech therapy. They think that within a year and a half to two years that mentally he might be fully recovered, but they don't know."
Also in the interview, Khloe opened up about Caitlyn Jenner's transition and why it seemed like she took it so hard. "When he did finally say it to us, we did feel like we were the last to know when we find out on camera for the first time," she revealed. "Your emotions are real and raw and I can't apologize for them."
While she admits that she probably took it the hardest of anyone in the family - at least outwardly - she says that now she's totally fine with it and she's thrilled to see how happy Caitlyn is.
