Self-excision of bilateral patellae treated by replantation: a report of one case

Absence of patella may be caused by congenital factors, trauma and surgical operations (patellectomy, etc). Complete absence of bilateral patellae is rare in clinical case. We report a case of posttraumatic bilateral patella excision. To the best of our knowledge, absence of bilateral patellae caused by self-mutilation has never been reported. Our patient and his family members were informed that the data concerning this case would be submitted for publication.
