Every surgical approach to total hip arthroplasty (THA)—posterior, anterior, or lateral and conventional or minimally invasive—has adherents and critics among orthopaedists who are seeking the best outcomes for their hip-replacement patients. Despite scores of published studies comparing these different approaches, no single best practice has yet emerged.

This complimentary JBJS webinar, moderated by James Waddell, MD, orthopaedic surgeon at St. Michael’s Hospital in Toronto and former President of the Canadian Orthopaedic Association, will update this ongoing debate by presenting recent evidence about five different surgical approaches to THA. The webinar will springboard off two JBJS articles:

Knut Erik Mjaaland, MD will discuss a registry study of more than 21,000 THAs that found no significant 5-year differences in implant survival or any-cause revision risk among four different approaches: two minimally invasive (anterior and anterolateral), and two conventional (posterior and direct lateral).

R. Michael Meneghini, MD will explain why his group’s analysis of 342 early-failure THAs concluded that the direct anterior approach may confer a greater risk of early femoral component failure due to aseptic loosening, compared with the direct lateral or posterior approaches.

After each author’s presentation, additional THA experts Anthony Unger, MD and Tad Mabry, MD will add clinical perspectives to the current state of this important research. During the last 15 minutes of the webinar, panelists will answer questions from the audience.

A live Q&A session follows the presentations and provides the audience with the opportunity to further explore the concepts and data presented.
