Why Patients Choose Dr. McLawhorn
Four principles guide everything we do:
Excellence
Dr. McLawhorn's track record speaks for itself — consistent 5-star reviews from patients and referring physicians alike, elite surgical volume, and recognition by Castle Connolly, Crain's New York Business, and the nation's leading orthopedic societies. When you choose Dr. McLawhorn, you're choosing the gold standard.
Innovation
Dr. McLawhorn is at the forefront of orthopedic hip and knee innovation. He adopts precision technology and cutting-edge techniques only when research confirms they improve outcomes — whether that's robot-assisted surgery, the bikini incision approach, or minimally invasive methods with faster recovery times. His treatment decisions are grounded in science, not trends.
Personalization
No two patients are alike, and no two surgical plans are either. Dr. McLawhorn takes the time to understand your specific anatomy, activity level, history, and goals; and tailors every aspect of your care accordingly. You will never feel rushed or like a number. He dedicates as much time as needed so you leave each appointment feeling informed, comfortable, and confident.
Partnership
Your recovery is a team effort. Dr. McLawhorn and his staff are accessible, communicative, and genuinely invested in your success. From your first consultation through your last follow-up, you'll have a dedicated team behind you every step of the way. They meet you where you are and keep you moving toward the active life you want to get back to.
