title: Detachment of the accessory fragment in "patella partita".
abstract: The authors report six cases of detachment of the accessory fragment in "patella partita". This lesion is often unrecognised, especially among athletes. It gives rise to painful symptoms that are at first severe and later less marked. These symptoms disappear completely in both acute and chronic cases with the removal of the detached accessory fragment.
