From Firehouse to Finish Line: Joe Matthews' Journey to Renewed Mobility
Why one firefighter chose total knee replacement and how it restored his strength, mobility and adventure

For Joe Matthews, resilience isn’t just a word—it’s a way of life. As a retired New York City firefighter with 22.5 years of service and more than 25,000 emergency responses, Joe spent his career running toward challenges. When knee pain began to interfere with his active lifestyle, he faced a new kind of obstacle that required courage of a different kind.
Joe grew up on Long Island and joined the FDNY at age 31. His years on the job were demanding—countless stairs, heavy gear, and high-pressure situations, including responding on 9/11. Off duty, Joe embraced adventure, testing his physical limits through marathons, triathlons, skiing, hockey, and even an expedition to Everest Base Camp. Fitness was always part of his identity.
After retiring from the fire department in 2012, Joe noticed something was wrong. At first, he chalked it up to getting older. That changed after a fall on a snowy curb left him unable to put weight on his leg. An X-ray revealed the truth: severe arthritis and no cartilage in either knee due to his decades of high-impact sports and outdoor activities.
Facing the Decision
Initially, Joe tried less invasive options like gel injections, which provided temporary relief. When the pain returned, his doctor explained that total knee replacement was the best path forward. Joe didn’t hesitate. At the age of 62 he was eager to continue living his active lifestyle and knew total knee replacement surgery was his best option. With the help of The Personalized Knee®, Joe chose a solution designed to fit his unique anatomy and support his goals for mobility and performance.
“When my doctor recommended replacing both knees my immediate thought was, ‘Let’s get it done,’ I didn’t realize that only about 10% of people get both knees done at once. I was up for the challenge,” Joe recalls.
The Road to Recovery
The first steps after surgery were humbling. Leaving the hospital required climbing six stairs, a task that felt monumental after days of immobility. But those steps marked the beginning of a journey defined by persistence and progress.
Recovery became Joe’s full-time mission. Each day was structured around therapy, movement, and healing. Hours were devoted to exercises that strengthened his legs, sessions with a continuous passive motion machine to restore flexibility and icing to manage swelling. It was demanding, but every small gain mattered. Ten revolutions on a stationary bike turned into 15, then 25, then minutes of steady pedaling. Each milestone was a reminder that progress was possible.
Joe’s Life After Surgery

Recovery opened the door to a new chapter defined by freedom and possibility. Now three years post-surgery, Joe moves with confidence. The limitations that once shaped his life disappeared. He returned to cycling, hiking, and the active lifestyle that had always been part of who he is. Within a year of surgery, he biked more than 5,000 miles across the country, a feat he credits to his years of fitness prior to his surgery.
Choosing knee replacement sooner rather than later can mean more years of doing what you love, whether that’s walking without pain, playing with family, or taking on adventures. With commitment to recovery, the right support, and solutions like The Personalized Knee, the journey leads not just to restored mobility, but to renewed confidence and a life fully lived.
