FDA approves knee-injury repair device for humans  cbasi
Updated: 2007-10-05 15:26:27
COLUMBIA, MO - A new knee-surgery device investigated by University of Missouri-Columbia researchers that will help to repair meniscus tears, which were previously defined as irreparable, has been approved by the FDA for use in humans.

Previous treatment options forced surgeons to completely remove the damaged portion of the meniscus, leading typically to painful, debilitating arthritis in the knee. Herb Schwartz, president and CEO of Schwartz Biomedical, LLC, James Cook, MU professor of veterinary medicine and surgery, and William C. Allen Endowed Scholar for Orthopedic Research in MU's College of Veterinary Medicine, developed the BioDuct Meniscal Fixation Device. Schwartz and Cook believe that patients with meniscus tears will now be able to have their meniscus saved along with long-term knee function.

The meniscus, a padding tissue that provides shock absorption and joint stability in the knee, is crucial for normal knee function. Surgeries for meniscus tears are common with approximately one million occurring in the United States each year. When meniscus function is deficient, bone rubs on bone and arthritis is likely to develop and progress. Because two-thirds of the meniscus is avascular (lacks a blood supply), a tear in that region will not repair itself. This new device will transport blood and cells from the vascular portion of the knee to the avascular portion of the meniscus. Supplied with blood and cells for healing, the previously untreatable meniscal tear now has the potential for allowing the knee joint to be saved.

Cook's research team performed the BioDuct surgery on 25 dogs that had worst-case scenario meniscal tears. With the BioDuct Meniscal Fixation Device, the meniscus in the dogs' knees had complete or partial repair after a few weeks in all cases.

"Currently, there are no other devices that can provide improved fixation over time," Schwartz said. "Therefore, the BioDuct device is set apart from the rest of the field."
