As long as there have been bone voids or defects, there has been a desire to fill them. The description of filling defects with various substances has been mentioned in ancient Hindu, Egyptian and Greek texts.
Learning of A CAOS Enhanced Mechanical Instrument System for Total Knee Arthroplasty: A CUSUM Analysis
Computer-assisted orthopaedic surgery (CAOS) has been shown to offer improved accuracy to total knee arthroplasty (TKA) compared to conventional techniques.1 Despite promising results, one of the drawbacks for surgeons to adopt CAOS technology may be the requirement of switching from conventional to CAOS-specific instruments.
As hospitals are facing mounting financial pressures in the current economic environment, time spent in the operating room has been identified as one of the most costly areas of hospital operations. As such, introduction of a new total knee arthroplasty (TKA) system to clinical care should demonstrate a minimum learning effort requirement.
Positive Early Clinical Outcomes Indicate Good Initial Fixation of the Alteon® Tapered Wedge Stem Compared to Other Wedge Stem Designs
The single-taper wedge stem design is derived from the cemented Mueller stem of the 1970s. Unlike fit-and-fill stems, which contact most of the metaphysis, tapered wedge femoral stems are designed to achieve proximal medial/lateral fixation.
