Alex Gu, MD, a hip and knee specialist with WashU Medicine, spends much of his free time at the playground with his two young daughters. It's the kind of everyday life he works to restore for his patients.
"I was drawn to orthopedics because it combines technical problem-solving with the opportunity to make a very tangible difference in someone's life," Dr. Gu says.
When he first sits down with a patient, before focusing on an X-ray or an operation, he wants to understand the person in front of him: what they're worried about, what they've lost to joint pain, and what they're hoping to get back.
In those conversations, Dr. Gu often hears people assume joint pain is just a normal part of aging. During Bone and Joint Week, he wants to challenge that idea.
While arthritis becomes more common with age, persistent pain and loss of mobility shouldn't automatically be dismissed as "just getting older."
He also encourages patients not to assume they're automatically "too young" or "too old" for a joint replacement.
"The right time for joint replacement isn't defined by a particular birthday," he says. "It's a decision we make together."
His message is simple: Don't wait until the pain becomes unbearable.
"If hip or knee pain is beginning to limit your activities or change the way you live your life, it's worth having a conversation about why."
One patient had spent years gradually giving up activities because of severe hip arthritis. After surgery, they came back and told Dr. Gu they had finally taken a family vacation they never thought would be possible.
"That has always stuck with me because it captures what we are really trying to accomplish," he says. "We aren't simply replacing a hip or knee. We're helping people regain independence and get back to the experiences and people that matter to them."
For some patients, that means taking a trip they've put off for years. For others, it's walking through the grocery store, returning to work, or playing with grandchildren without constantly worrying about pain.
