title: Impingement (acetabular side).
abstract: Rim impingement lesions vary based on the underlying pathology. In general, rim impingement occurs with anterosuperior overhang, coxa profunda, protrusio acetabuli, and acetabular retroversion. The method for addressing these pathologic lesions depends on location and size of the impingement lesion, the underlying pathology, and the degree of labral damage. The ultimate goals of surgical management include accurate localization of the rim impingement lesion, adequate removal of the bony impingement lesion, and preservation and refixation of the viable labral tissue. If the surgeon feels that these goals cannot be accomplished safely and effectively by arthroscopic methods, alternative procedures should be considered.
