Taking the Lead in Joint Replacement
Anthony J. DiStasio, II, MD

A revolutionary new knee replacement material is helping to make Chesapeake General Hospital a leader in joint replacement. orthopaedic surgeon Anthony J. DiStasio II, who practices at Chesapeake General, is one of only about 75 surgeons in the nation who is using the new xxxxxxxxxx knee implant, a technologically advanced material that is projected to last significantly longer than traditional implants made of cobalt chrome.

This is one of the most exciting advancements in orthopaedics in the last 20 years," said Dr. DiStasio. "testing shows an 85 percent improvement in the wear rates of the implant, which makes it an excellent alternative for younger, more active patients."

Generally, traditional cobalt chrome knee implants are expected to last for about 15 to 20 years, which may be fine for older patients, over age 65. However, younger patients suffering from arthritis or knee injury may have delayed implant surgery, knowing the implant would not last and they might need another surgery later in life.

Dr. DiStasio explained that the new implant is a type of alloy, with a much harder, scratch-resistant surface. In a joint such as the knee, which cycles an average of three million times each year, a smooth surface means less friction and better durability. Also, the material - oxidized zirconium - is less likely to cause allergic reactions than traditional implants, which may affect a minority of people who are sensitive to certain metals. "I recently visited the engineers who designed and tested this implant, which was fascinating," Dr. DiStasio said. "they invested more than $10 million and spent over 12 years, developing and refining it."
