Patients suffering from severe arthritis now have an option for total ankle replacement that offers increased mobility and pain relief without permanent metal implants. Pioneered by Daniel K. Lee, D.P.M., F.A.C.F.A.S., at UC San Diego Medical Center, this technique is the first in the U.S to offer arthritis sufferers a non-metal, biological ankle replacement.
"Up until now, patients have had two options for replacing their ankle joints: metal implants or fusion of the joints," said Lee, director of foot and ankle surgery at UCSD Medical Center. "Now there is an option that actually restores the ankle with an FDA-approved biologic material that is similar to the collagen found in cartilage."
During a two hour minimally-invasive surgical procedure, Lee, a podiatric foot and ankle surgeon, removes the damaged cartilage around the ankle joint through a four centimeter incision. The collagen material is then molded into the joint where it adapts to the contour of the patient's ankle.
"Unlike a metal device, the advantage to this material is that the implant can be customized in size and contour for every patient's individual need," said Lee. "No matter how the patient's ankle is shaped, the collagen is a perfect fit."
