Influence of the Crowe rating on the outcome of total hip arthroplasty in congenital hip dysplasia.
Few studies have examined the relationship between the severity of congenital dysplasia of the hip (CDH) and the clinical outcome of total hip arthroplasty. The authors have used a prospective design to study this question, using the Crowe grade to assess the severity of CDH. There were 71 patients with CDH operated on using the S-ROM total hip (Joint Medical Products, Stamford, CT); the control group was composed of 22 patients without CDH operated on using the same implant during the same period as the CDH patients. The patients with mild CDH did not have a different outcome from the patients without CDH with respect to Harris hip score or limp. The higher the Crowe grade, the more complications occurred. It was also found that the patients in whom the true acetabulum was not used had a significantly higher incidence of limp.
