Decades of selective breeding to reduce the prevalence of hip and elbow dysplasia (HD and ED) in Swedish dogs, based on phenotypic assessment of radiographic hip status, has had limited success. The prevalence of dysplastic dogs is still high in many large-sized and giant breeds and among the most common causes for euthanasia and costly veterinary care in numerous breeds are joint-related probl...

Purpose: Osteoarthritis (OA) is the most prevalent joint disease with an estimated prevalence of 8% in general population. Hip morphology has been marked as important risk factor for development hip OA. One types thought to increase OA pincer morphology, which overcoverage femoral head by acetabulum. The may result neck impinging against acetabulum during motion and possibly creating intra-arti...

BACKGROUND Femoroacetabular impingement (FAI) is reportedly a prearthritic condition in young adults that can progress to osteoarthritis. However, the prevalence of FAI is unknown in the young, active population presenting with hip complaints. QUESTIONS/PURPOSES We sought to determine (1) the prevalence of radiographic findings of FAI in a young, active patient population with complaints loca...

OBJECTIVES To prospectively investigate whether hip shape variants at baseline are associated with the need for future total hip replacement (THR) in women and to validate the resulting associated shape variants of the Cohort Hip and Cohort Knee (CHECK) cohort and the Chingford cohort. METHODS Female participants from the CHECK cohort without radiographic OA (Kellgren-Lawrence score <2) at ba...
