Kenzie was referred to Alder Hey when he was four, after his family noticed he'd developed a limp that didn't go away.
A doctor diagnosed Kenzie with Perthes disease, a rare condition that affects the femur in the leg making it soft and breakable. In early 2012, Kenzie underwent an operation to reshape the bone in his leg, leaving him bed-ridden in a hip cast for three months.
Kenzie's mum, Tara said: "The worst thing for Kenzie was that he was told he couldn’t take part in any high impact sports like football. He had been a little livewire so this was really difficult.
“What broke my heart was when he was watching the Paralympics and saw the disabled runners using false limbs. He asked me if his leg could be cut off so he could have a false one and be able to run around again.”
He has since undergone months of intense physiotherapy and hydrotherapy as well as a second operation. However, despite still having muscle damage and weakness in the affected leg, Kenzie is determined and positive.
In May 2015, Kenzie conquered Oli's Safari Walk without using his wheelchair - an incredible achievement!
“Kenzie is determined to do something to help Alder Hey as they have done so much for him,” said Tara, who told how Kenzie organised a toy collection at his school, to donate to children spending Christmas at Alder Hey. He delivered the toys on the day of his operation.
