Clinical and Roentgenographic Assessment of Total Hip Arthroplasty

Abstract

A new total hip scoring system is presented and applied in a group of patients who were treated by revision of total hip arthroplasty. The Mayo hip score combines clinical (80 points) and roentgenographic (20 points) data in a 100-point score. The roentgenographic input into the score decreased the percentage of good–twxcellent results because of the high frequency of roentgenographic signs of loosening. With the Harris rating, there were 63% good–to–excellent results, 12% fair results, and 26% poor results a mean of 4.25 years after component revision of total hip arthroplasty. With the Mayo system, there were 52% good–to–excellent results, 19% fair results, and 29% poor results a mean of 4.25 years after revision. A modification of the roentgenographic rating system would apply the Mayo hip score to noncemented total hip arthroplasties.
