title: Clinical and roentgenographic assessment of total hip arthroplasty. A new hip score.
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-to-excellent 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.
