Wright Launches BIOFOAM Cancellous Titanium Tibial Base for Total Knee Replacement

January 31, 2008 - Wright Medical Group Inc. today announced a limited launch of the BIOFOAM Cancellous Titanium Tibial Base, which features a proprietary bone-like titanium with a roughened texture that “bites” into bone for cementless fixation of the implant.

The latest addition to Wright’s ADVANCE Knee Systems, the BIOFOAM Tibial Base featuresBIOFOAM Titanium also features a trabecular structure intended to mimic bone and contribute to bone in-growth.

Cementless fixation is a growing trend in knee reconstruction due to younger patients resulting from active lifestyles and increased body weight. It is theorized that cementless knees may have longer survivorship than cemented designs. One of the most important requirements to achieving solid bone in-growth in a cementless knee is immediate, rigid fixation of the implant to the bone. The rough surface of BIOFOAM Titanium is designed to “bite” into bone and enhance fixation. It also features a trabecular structure intended to mimic bone and contribute to in-growth.

“I believe there is quicker in-growth into the BIOFOAM base [than in-growth into an HA-coated base],” said associate professor of Orthopaedic Surgery and Director of the Joint Replacement Center at the Medical College of Georgia, R. Scott Corpe, M.D. “Combine the BIOFOAM [base] with the ease and accuracy of putting this knee in with the ODYSSEY instruments, and the ADVANCE knee is a great product with superb intraoperative flexibility capable of handling 99% of primary knee demands.”
