FDA Clears XpandOrtho ‘Balancing’ Knee Surgery Device
FDA has cleared an XpandOrtho 510(k) for its electronic soft tissue balancing instrument for total knee replacement surgery. The sterile-packaged wireless disposable device uses “multiple miniaturized sensors and actuators to perform multiplanar balancing of the knee joint during a full range of motion,” the company says. “The device uses a novel constant pressure bellows system which wirelessly communicates with a display to provide dynamic multiaxial balance and selection of optimal thickness of the tibial component.” It is designed to be used by surgeons whether they choose to make the femoral cut first or the tibial cut first. Soft tissues can also be released with the device in place enabling real time visual feedback to the surgeon, it says.
