[Hip arthroscopy. Portal technique and arthroscopic anatomy]

In hip arthroscopy everything revolves around entry points. Only with a precise entry technique are safety and efficiency guaranteed. Most pathological changes of the hip for which an arthroscopic intervention can be used are located in the central compartment: two lateral (anterolateral and posterolateral) and one anterior portal are the three standard portals allowing an optimal approach to practically all pathological changes in this compartment. Significant diseases and lesions can occur in the peripheral compartment which would be overlooked by arthroscopy of the central compartment. Two portals are needed for arthroscopy of the periparal compartment: the anterolateral, as well as one distally, converging on the ventral neck of the thigh. Hip arthroscopy is undergoing continual development, however, there are still major requirements for clarification of the pathology and pathomechanisms of injuries and diseases of the this joint.
