Latics boss Roberto Martinez was furious with the challenge and branded it a "football crime".
McCarthy told the Sunday Mail: "It's been murder watching from the stands, especially against the likes of Arsenal who we got a great point from in midweek.
"This is the first serious injury I've had in my career and hopefully it will be the last.
"What added to the frustration was the fact I had become a regular in the team. It's still a dream come true for me to be playing in the Premiership every week.
"So I was really down for the first couple of months. Thankfully I can now see a bit of light at the end of the tunnel and it won't be long until I'm back playing.
"I haven't heard anything from Muamba but that doesn't bother me. It was a stupid tackle but I don't want to criticise him. He could have came up to me and said, 'Sorry, it was a bad tackle, I didn't mean it.'
"Normally the player would maybe send you a text or something like that. A couple of the Wigan boys know him and said he would. But nothing came of it.
"I just want to forget it - the doctors have put a rope in the ankle to hold the bone and say it will be as strong and stable when I come back as it was before."
