Survivorship of Monoblock Cobalt Chrome Alloy Acetabular Components: Five to Twelve Year Results

Recently, monoblock cups have increased in popularity for hip resurfacing and large femoral head total hip arthroplasty. However, there have been no studies specifically evaluating the durability of this type of cup. The purpose of this study was to define the midterm survivorship of cobalt-chrome alloy, monoblock acetabular components.
