It has been nearly a decade since the introduction of this Specialty Update section in The Journal. We have covered many topics that were considered to be contemporary and controversial. In the current update, we have elected to include reviews on (1) the outcomes of primary total hip arthroplasty, (2) the outcomes of revision hip arthroplasty, (3) hip resurfacing arthroplasty, (4) complications, and (5) practice management. The major new information in the past year is in epidemiology and hip resurfacing arthroplasty.
