Low Incidence of Groin Pain and Early Failure with Large Metal Articulation Total Hip Arthroplasty

摘要

BackgroundLarge-diameter metal-on-metal articulations reportedly improve stability and wear in THAs. However, some reports suggest some patients have unexplained hip and early failures with these implants. Thus, the potential benefits may be offset by these concerns. However, the incidence of these problems is not clearly established.
