    Hello, my name is Kenneth "Buck" Smith. I'm an orthopedic surgeon with Signature Orthopedics specializing in foot and ankle surgery.

    Playing varsity sports at Washington University in St. Louis I had a couple foot and ankle injuries. So I had a lot of encounters with foot and ankle doctors and through that experience I started to like foot and ankle more and more; understanding the complexities of the gait cycle and how impacts on the patient's foot and ankle really impacted their life and how much of a difference you can make by fixing those problems.

    You get patients across a broad spectrum of life. You've got really young patients who are really active getting injured during sports activities, but you also get a lot of patients who are older. You get a really wide breadth of different patients and different stories between the trauma and the chronic conditions.

    Having the technical skills kind of goes without saying: you have to be good in the OR. Also knowing which patients to operate on and which patients that non-operative would be a better route for them to minimize and mitigate the risk. Kind of meeting patients where they're at and coming up with a plan to maximize their outcome.

    The whole encounter is not just what we see in the exam room. A lot of the encounter is them healing afterward and they're at home and whether they live by themselves in a third floor apartment versus having a large family where they're going to have help. So trying to figure out the social factors that are going to impact their outcome.

"The foot and ankle subspecialty encompasses a large variety of conditions, making every day unique and exciting. I love seeing the smiles on patients’ faces after we have successfully treated their conditions and their pain is gone."
