Finite Element Modeling of Chondrolabral Lesions in Pincer-Type Femoroacetabular Impingement.

Background: The prevalence of chondrolabral lesions due to femoroacetabular impingement (FAI) is 93% in cadaveric material. As a biomechanically determined factor, it can lead to hip destruction and early osteoarthritis in pincer-type impingement. The aim of this work was to study the biomechanism and stress-strain behavior of chondrolabral lesions in pincer-type impingement during daily activity-associated movements.
