Advanced Surgical Design & Manufacture Limited (ASDM) is an Australia-based company engaged in the sale, manufacture and design of surgical implants. ASDM's principal product, the Active Knee, is a total knee replacement prosthesis. It is a cementless, metal/polyethylene, cruciate retaining design. ASDM manufactures a range of surgical screws, saw blades and kirschner wires (special wires used to secure bone fragments). These supplement ASDM's knee products and provides essential components to orthopaedic surgeons. ASDM has developed and markets a carpal plate design, used to treat wrist fractures and for the fusion of arthritic and osteoporotic carpal bones. In addition, ASDM has the exclusive license for a electropolishing process on medical cobalt alloy implants which removes embedded polishing particles and surface carbides, improves friction against polyethylene and improves surface tension.
