Abstract

Tears of the acetabular labrum can lead to pain disability and osteoarthritis Several pathomechanisms have been proposed including femoroacetabular impingement FAI Labral tears have been reported to occur in the presence of even subtle deformities of the acetabulum and femoral headneck junctionRadiographs of 123 hips in 116 patients receiving surgical treatment for FAI were analyzed and correlated to the presence and extent of labral lesions Radiographic parameters of the acetabulum included acetabular index of the weightbearing zone centeredge angle inclination of the acetabulum lateral head extrusion index and retroversion On the femoral side neckshaft angle asphericity of the femoral head superior and anterior alpha angle offset and offset ratio were measured Osteoarthritis was graded according to Tönnis and Kellgren and Lawrence Labral lesions were graded according to the modified Beck classification A correlation between labral lesions and age gender affected side type of impingement and presence and extent of chondromalacia also was testedNo correlation was found between presence or extent of labral lesions and any radiographic parameter tested except osteoarthritis classification The severity of labral lesions correlated to the severity of acetabular chondromalacia as well as patient age Beck Grade 0 versus Grade 1 Beck Grade 0 versus Grades 1 and 2Each author certifies that his or her institution approved the human protocol for this investigation that all investigations were conducted in conformity with ethical principles of research and that informed consent for participation in the study was obtained
