But the Ospreys flanker has played three games in the last 10 days to show new Wales Coach Warren Gatland he is ready to play a major role in next month's RBS Six Nations campaign.
Jones said: "I'm looking to make up for lost time. It's been a torrid time and anyone who has had a serious injury will say the same. I've been through some dark times when I wondered if I'd ever be in one piece again.
"But there's no bigger motivation than playing on the biggest stage. It's like an addiction and you just can't replace it.
"The biggest fear I had was playing for Swansea before Christmas and having a setback. But I spoke to the medical staff and knew myself I was ready and think I've backed that up in the last three games.
"I want to play at the top and the three matches over Christmas are as good as it gets. I just want to play as many games as I can.
"I know it will take me six to eight games to back to form but I'm working hard and trying to take all the opportunities I'm given."
