Complications associated with hip resurfacing arthroplasty

Hip resurfacing arthroplasty is an old orthopedic concept that has undergone a resurgence of interest in the past decade. Because of the rapid increase in the number of procedures being performed, previously recognized complications have begun to recur. This article focuses on complications that are related to the hip resurfacing procedure such as femoral neck fractures, avascular necrosis, raised metal ion levels, and sound initial and durable long-term fixation of an all-metal monoblock cobalt/chrome acetabular component. Dislocation rates after resurfacing and other complications are briefly discussed.
