For the Truliant cruciate retaining design, short-term data show it performs better than the aggregate of all other cruciate retaining total knee arthroplasties performed and recorded in the American Joint Replacement Registry, the Australian Orthopaedic Association National Joint Replacement Registry, and the United Kingdom's National Joint Registry databases.
