The future remains bright for Keane, whose twin brother Michael has been making great strides, and he is remaining philosophical about his lengthy absence.
"It was great to see all my family supporting us and cheering us on," he added. "They've waited a long time. I know my Mum would have been quite nervous in the crowd and they'll be pleased to see me just get through it.
"First and foremost, I've just got to keep working hard and get myself back on track to make up for lost time now. It's been a big learning curve for me and something I've just had to deal with. But that's part of football and I've just got to continue to work hard and see where that takes me. I've got to just play as many games as possible and get as many minutes under my belt as I can, keep training and build on my match sharpness to just push on.
"Probably one of the biggest things was getting back in training with the lads and back amongst the team. That's been a big plus as, throughout the year, I spent a lot of time on my own and one-on-one with the physio. One of the biggest frustrations was coming in and seeing everyone train while I'm slogging it out in the gym.
"I've played with these guys for 10 years now, the majority of the group and with Mike, so it was nice to be back."
Keane's leveller got United back into the game against Bolton at Salford City Stadium with Jesse Lingard netting twice and Tom Thorpe also getting on the scoresheet in the second half.
