Meet Dr. Zaid
As an orthopedic surgeon specializing in hip and knee replacement surgery, I find immense satisfaction in helping patients reclaim their mobility and quality of life. Each day presents a unique challenge, from diagnosing complex conditions to meticulously planning and executing surgical procedures. The intricacies of joint mechanics fascinate me, and I take pride in using the latest techniques and technologies to ensure optimal outcomes. Witnessing the transformative impact of my work—seeing patients walk, run, and embrace life without pain—fuels my passion for this specialty. The blend of precision, innovation, and the profound gratitude from those I help makes every moment in the operating room rewarding.
I am a fellowship trained hip and knee replacement surgeon who specializes in minimally invasive direct anterior hip replacement as well as direct anterior revision surgery. I also specialize in primary knee replacement surgeon as well as knee revision surgery. In addition to joint replacement surgery I also have significant experience in managing and treating periprosthetic hip and knee fractures.
