One Intraoperative Dose of Tranexamic Acid is Safe and Effective
in Revision Total Knee Arthroplasty
Kevin Smit, MD, London, ON, Canada
Doug Naudie, MD, FRCSC, London, ON, Canada
Fiona E. Ralley, MD, London, ON, Canada
James Howard, MD, London, ON, Canada
One 20 mg/kg intraoperative dose of TXA significantly reduced
red blood cells loss and transfusion rates in patients undergoing
revision TKA and was not associated with an increased
complication rate.

The Role of Primary Bearing Type in Revision Total Knee
Arthroplasty

We compared the complexity of revision procedures for failed
fixed- (FB) and mobile-bearing (MB) knee designs. Our data show
that MB knees fail earlier and require greater constraint than FB
knees.

Recurrent Periprosthetic Joint Infection: Persistent or new
Infection?

Most failures following two-stage treatment for PJI appear to
occur as a result of “new” infection or infection by an organism
that was not detected during initial surgery for PJI.

Two-Stage Revision Total Knee Arthroplasty is Associated with
High Complication and Failure Rates
Christopher Pelt, MD, Salt Lake City, UT
Jill Erickson, PA, Salt Lake City, UT
Mike Anderson, MS, ATC, Salt Lake City, UT
Lucas Anderson, MD, Salt Lake City, UT
Erik Kubiak, MD, Salt Lake City, UT
Christopher L. Peters, MD, Salt Lake City, UT
A 17% reinfection rate, with 28% receiveing reoperations, and
6% complication rate with two-stage revision TKA, although
comparable to previous reports, remains concerning.

Systematic Review of Static and Articulating Spacers for
Infected Total Knee Arthroplasty Revision
Qais Naziri, MD, Brooklyn, NY
Aaron J. Johnson, MD, Baltimore, MD
Christopher R. Costa, MD, Dallas, TX
Michael A. Mont, MD, Baltimore, MD
Robert Pivec, MD, Baltimore, MD
Articulating spacers offer the potential for greater range
of motion at final follow-up, however, they should be used
cautiously in complex infection cases.

Reported Pain After Total Knee Arthroplasty: A Prospective,
Randomized Trial Comparing Two Surgical Approaches
Wayne E. Moschetti, MD
Ishaan Swarup, BA, Stockton, CA
Stephen R. Kantor, MD
Kevin F. Spratt, PhD

Comparison of post-operative pain after total knee replacement
performed with contemporary minimally invasive surgery
principles using either a quad sparing approach or medial
parapatellar arthrotomy

Failure Mechanism of Knee Arthroplasties: A Retrospective
Analysis
Kathi Thiele, MD, Berlin, Germany
Carsten Perka, MD, Berlin, Germany
Georg Matziolis, Berlin, Germany
Hermann Mayr, MD, Munich, Germany
Michael Sostheim, MD, München, Germany
Kristin Seidemann, Berlin, Germany
Robert Hube, MD, Munchen, Germany
All results subsumed we see an explicit shift from aseptic
loosening and polyethylene wear to instability, malalignment and
periprosthetic infection as main failure mechanisms.
