In 1879, the French surgeon Segond described existence of a 'pearly, resistant, fibrous band' at anterolateral aspect human knee, attached to eponymous fracture. To date, enigma surrounding this anatomical structure is reflected in confusing names such as '(mid-third) lateral capsular ligament', 'capsulo-osseous layer iliotibial or 'anterolateral and no clear description has yet been provided. study, presence characteristics Segond's 'pearly band', hereafter termed ligament (ALL), was...
