Rapidly Progressive Arthritis in Femoroacetabular Impingement: Patient Characteristics and Risk Factors for Total Hip Arthroplasty by the Age of Forty

摘要

Background: Femoroacetabular impingement (FAI), particularly cam-type, is now well accepted as a risk factor for the development of hip osteoarthritis (OA). However, many hips with FAI morphology will never develop hip pain or OA, identifying that our current understanding of FAI disease progression remains limited. The purposes of this retrospective case-control study were to (1) report the patient and disease characteristics of patients with rapidly progressive FAI requiring hip arthroplasty by the age of 40 and (2) to identify patient and imaging factors associated with rapidly progressive FAI.
