ASDM's principal product, the Active Knee, is a primary total knee replacement prosthesis. It is a cementless, metal/polyethylene, cruciate retaining design. Its design features include:

• unique, exclusive surface finishing (Ultrapolishing) that imparts wear characteristics approaching that of ceramics;
• cementless design with a sintered hydroxyapatite coating that encourages rapid bone bonding with the implant. For patients that are unsuited to a cementless implant, a cemented version is also produced;
• a cruciate retaining design that, for a total knee, minimises the invasiveness of the operation and patient trauma.

As a consequence, the ASDM Active Knee has an outstanding patient success rate. In a paper published in 2005 by the Journal of Bone and Joint Surgery (UK), which prospectively reviewed 1000 patients with up to 10 year outcomes, reported excellent patient functional results and an extremely low incidence of revisions (complications). ASDM considers this an industry-leading performance, given the relatively conservative (bone preserving) nature of the design.

Importantly, the ASDM Active Knee has a clinical history extending over 15 years, demonstrating excellent patient outcomes, so it can be considered a thoroughly proven design. The length of clinical history is significant because there have been a number of instances where competing knee designs have been  introduced, only to suffer a relatively high rate of issues in patient use.

The ASDM Active Knee also has a growing number of supportive published academic papers as well as thousands of knees implanted worldwide.
