The writers present the case of a small girl affected by Larsen's syndrome. Her brother had the same syndrome. Surgical reduction of the dislocated knees was performed at the age of two months, followed by immobilisation in a spica plaster. At operation it was found that both patellae, which are cartilaginous at that age, were absent. On the basis of recent literature and the heterogeneous manifestations of the syndrome, the authors discuss the pathogenetic theories, the differential diagnosis, and the current therapeutic possibilities.
作者介绍了一名患拉森综合征的小女孩的病例。她的哥哥也患有同样的综合征。两个月大时对脱位的膝盖进行了手术复位，随后用髋人字石膏固定。手术时发现，在那个年龄应为软骨的两个髌骨均缺失。基于近期文献以及该综合征的异质性表现，作者讨论了发病机制理论、鉴别诊断和当前的治疗可能性。
