title: Causes of Primary Total Hip Arthroplasty in Active Duty Soldiers-Are Recurrent Medical Assessments Associated With Reduced Rates of Secondary Osteoarthritis in This Population?
abstract: The purpose of this study was to analyze the different causes of symptomatic osteoarthritis (OA) of the hip joint in active duty soldiers requiring a total hip arthroplasty and the hypothesis that soldiers had a reduced prevalence of secondary OA as a result of a selection process that has taken place through multiple medical assessments during their military career. We analyzed patient records from 2006 to 2012 for male patients ≤60 years with OA of the hip and indication for total hip arthroplasty in a military hospital in which civilian patients are also treated. About 44 military patients (MP) and 69 civilian patients (CP) were included. The prevalence of different causes of OA of the hip did not differ significantly in both groups (primary OA MP: 59.1% [n = 26], CP: 56.5% [n = 39]; dysplasia MP: 25.0% [n = 11], CP: 24.6% [n = 17]; femoral head necrosis MP: 11.4% [n = 5], CP: 13% [n = 9]; post-traumatic OA MP: 4.5% [n = 2], CP: 5.8% [n = 4]). In conclusion, recurrent medical assessments that are usually based alone on clinical examinations were not able to reduce the prevalence of prearthrotic deformities as a joint-specific risk factor for the development of symptomatic hip OA in our military collective.
