John Velyvis, MD - Orthopedic Surgeon

John Velyvis, MD

Board certified in orthopedic surgery, John Velyvis, MD specializes in minimally invasive knee and hip surgery. He is an expert in the use of robotic-assisted partial knee resurfacing. Robotic Assisted Partial Knee Resurfacing is a new discipline in the treatment of arthritic knee joints and Dr. Velyvis has emerged as one of the leaders in the field. At one point, he performed 12% of robotic assisted surgeries in the US, logging 625 partial knee resurfacing procedures, 560 of which were performed using robotics.

Dr. Velyvis believes traditional total knee replacement surgery has a place in orthopedics but that newer techniques for partial knee resurfacing are emerging that appear better for certain patients. In traditional total knee replacement surgery, “Two critical ligaments are surgically severed. These are the very ligaments that guide motion and stability to the joint. We focus on knee preservation, and none of that trauma even takes place with this new surgery. The surgeon uses computer mapping to guide the robotic resurfacing. Minute amounts of tissue are removed. The tolerances are very precise, far more exacting than could ever be accomplished unaided by the robot. We use a very small implant within the joint itself, and thereby eliminate the pain of arthritis, with shorter and easier recovery times.”

Dr. Velyvis also works as an educator and consultant, and has lectured and published extensively on joint replacement topics within the field of orthopedics. To learn more about Dr. Velyvis, visit his website
