Total hip arthroplasty (THA) is a common procedure for osteoarthritis, complications due to hip fractures, rheumatoid arthritis, and congential dislocation of the hip. Are there variables that can identify patients at risk for unsuccessful outcomes after this surgery? In "Prediction of Functional Outcome at Six Months Following Total Hip Arthroplasty" (November 2012), Dr Emily Slaven concluded that such variables as body mass index, age, and sex could be used to identify patients at risk for less favorable outcomes after THA. In this podcast, Slaven is joined by orthopedic surgeon and researcher Dr Robert Wagenmakers and moderator Dr Rebecca Craik to discuss her study and other current research on the topic. They also discuss the influence of different surgical approaches on outcomes and compare postoperative rehabilitation approaches in the United States and the Netherlands.
