Hip arthroscopy for space-occupying lesions within the acetabular cotyloid fossa

Standard hip arthroscopy emphasizes access to disease within the peripheral compartment. The author describes precise access to the central compartment for removal of space-occupying lesions within the cotyloid fossa. These lesions can compromise the space available for the ligamentum teres and possibly contribute to the development of cam/pincer lesions and articular-sided labral tears by altering the congruency of the hip joint. Importantly, this novel approach does not impair the ability to complete the more widely known surgical techniques used within the peripheral compartment.
