Personal Statment

The thing I want patients to understand about hip and knee arthritis is knowing when you need to seek treatment. Pain lasting for more than 4-6 weeks is probably not going to respond to ibuprofen. There's different treatments depending on your age and what's exactly going on. I want to get to know you and figure out what's the best treatment for you, whether that's doing medication or physical therapy or surgery. Seeing patients from start to finish is important, that way you can have continuity of care so that you know exactly what's going on during their entire treatment process.

My core reason for going into medicine is to offer personalized treatment. I'm not a "operate first, meet you second" kind of doctor.

    Karen Douglas

    “The best move I've made”

    As a barefoot water skier, Karen Douglas had to trust her body—until she couldn’t.

    Karen relies on her knees to keep her active and doing what she loves. But when an old knee injury flared up, and cortisone shots weren’t enough to manage her pain, she came to UK HealthCare for a more permanent fix. There she met with Dr. Stephen Duncan, an athlete himself. Dr. Duncan recommended a new type of knee replacement that was a better fit for Karen’s active lifestyle, with a much shorter recovery time. It was the right choice: Within a year Karen was back out on the water out of pain and doing what she loves most.
