C hapter 1 Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE) About Hip and Knee Replacement Joint replacement is becoming more common, and hips and knees are the most frequently replaced joints. According to the Centers for Disease Control and Prevention (CDC), 332,000 total hip replacements are performed in the United States each year. In a recent year, 542,000 total knee replacements were performed. Hip or knee replacement is a surgical procedure in which the diseased or damaged parts of the hip or knee joint are removed and replaced with new, artificial parts. The new joint, called a prosthesis, can be made of plastic, metal, or both. Understanding Veins and Arteries The ongoing flow of blood from the heart to the body and back to the heart again is called circulation. Blood vessels carry blood throughout your body. Veins are the vessels that return blood that is lacking oxygen from the tissues back to the heart. Arteries are blood vessels that carry blood away from the heart. While most arteries carry blood with oxygen, there are two exceptions to this norm, the pulmonary and the umbilical arteries. 4
