Teen survivor Liam Knight smiles goodbye to rehab Teen survivor Liam Knight has returned to school after a remarkable recovery. Liam Knight, pictured after waking up from a coma in hospital earlier this year. HE is known as the miracle boy who wasn't expected to survive: yet just four months on, Liam Knight returned to a hero's welcome at school. "This is one of the most special days the school has had in terms of miracles," St Pius X College counsellor Rick Russo said. It's good to have him close by again and see the continued determination, the encouragement and supportive group of friends. Liam's special day out was part of a segment being filmed by Nine's 60 Minutes, which will air in July. Liam was allegedly injured by gatecrashers at an 18th birthday party. The 17-year-old schoolboy last week was discharged from the Royal Rehabilitation Centre at Ryde, where he has been recovering since suffering a life-threatening brain injury at a party earlier this year. When Liam was rushed to Royal North Shore Hospital in the early hours of January 11, doctors told his parents Trevor and Mary Knight to "prepare for the worst." But sheer determination, leading medical treatment, and a lot of love and encouragement from his supportive family and friends have seen Liam beat the odds. Finally out of rehab, second stage of recovery is finished but still have a long way to go. Thanks to all the people who helped me out," Liam recently posted on Facebook. Not long after he was hurt, it seemed like a faraway dream that Liam would be well enough to return to school.
