A man who snapped both legs while bouncing on a trampoline had to undergo three rounds of surgery to walk again. Robert Harrison, 38, was playing around with his children on the trampoline when he felt two "excruciating pops" in his knees as he attempted a front flip - rupturing his tendons in both knees. After losing feeling in his lower limbs, Robert thought he was paralysed and couldn't look down - fearing that his bones could have been sticking out of his legs. Paramedics quickly arrived on the scene and Robert initially thought he had dislocated his legs, even asking the paramedics to pop them back in place so he could get to work. Robert was told upon arrival at Kaiser Permanente Roseville Hospital, California, US, that he had ruptured both of the tendons in his knees and would require immediate surgery. The dad-of-four then spent six weeks with his legs in straight braces and in a wheelchair, making life "extremely difficult" and leaving him feeling "helpless". Througout the six weeks, Robert gained some mobility back in his legs and was able to walk in the straight leg braces in August 2021. However, after he tripped and fell on a curb, the staples in his leg split open and he was rushed back to hospital where he had to wait over 24 hours for surgery to close up his leg. After a few more setbacks and another round of surgery to bring his kneecaps back down to where they're supposed to sit, Robert's legs have completely healed but he still struggles to walk. Despite this, Robert is down 100lbs from the 300lbs he weighed at the time of the accident on the 31st July 2021. Robert has also revealed that he was drinking on the day and vowed to quit - and he's due to hit one year of sobriety on the 17th December. Robert, a corporate security surpervisor, who lives in Folsom, California, US, with his wife, Jessica Harrison, 37, a marketing manager said: "I felt completely helpless - I suffered a lot mentally. "Day to day activities were made very difficult and terrifying after the injury. "I remember I was playing with the kids and we had just bought the trampoline. "I decided to have some fun on it and I wanted to go viral with some flips. "Next thing I know I feel two excruciating pops and I couldn't feel my legs. Everything went numb. I thought I was paralysed. "I didn’t even want to look down as I thought my bones might be sticking out of my legs. "When I got to the hospital they told me that I had torn both tendons and that I'd require surgery. "They said they’d never seen that before. "I realised that your life can change instantly and you have to be ready for anything. "That's what motivated me to be better than I was before. "I wasn’t in the best health during the accident as I was 300lbs. "Now I've lost 100lbs and quit alcohol. "The greatest gift I can give my family is a sober dad and husband." After his surgery, Robert spent six weeks in braces, unable to bend his knees and fearing he was going to re-injure himself. "I was using a wheelchair and a walker and life was extremely difficult," he said. "I had to crawl up stairs with legs straight, had to use the bathroom that way, had to sleep with my legs in the straight braces. "I was so terrified of falling and re-injuring myself." However, after making some steady progress, Robert hit a setback. His leg split open after he tripped on a curb and he and found himself back in hospital for another round of surgery. He said: "They told me I didn’t re-rupture the tendon but they needed to close me back up. "I waited over 24 hours for surgery and my leg was wide open the whole time. "They had to put the staples back in and then I was back in the straight leg braces." Unfortunately, progress had been slow since his second surgery and Robert went back to hospital for an MRI scan. The MRI revealed that his patella’s had stretched back out and his kneecaps were sitting at the bottom of his quadricep muscle - which required another procedure to fix. Despite a successful operation, Robert admits he still struggles with the pain. "My kneecaps are still sitting higher than normal and I can't build leg muscle without excruciating pain," he said. "Everything is completely healed but the mental struggle is difficult because I'm afraid I'm going to fall again. "The biggest obstacle now is walking normally. I basically had to learn to walk again." Robert says not being able to play with his children has "destroyed" him. He says he can no longer play games with his four children - two boys, aged 12 and eight ,and two girls, aged five and one. "It's something I don’t talk about a lot," Robert said. "It destroys me internally. I love to run around with my kids and I just can't do those things and haven't been able to since the accident. "That’s what probably hurts me the most." Despite all he's been through, Robert also decided to use the accident as motivation to better himself moving forward. He admits that he wasn't in the
