Abstract
in English, Portuguese

Objectives: To evaluate the prevalence of a vascular network adjacent to the insertion of the pes anserinus, so that it could be used as an anatomical reference point to facilitate harvesting flexor grafts for arthroscopic reconstruction of the anterior cruciate ligament (ACL).

Methods: Thirty patients with ACL tears who were going to undergo ACL reconstruction using the tendons of the semitendinosus and gracilis muscles as grafts were selected randomly. During the harvesting of these tendons, the presence or absence of this anatomical reference point was noted.

Results: All the patients presented a vascular network of greater or lesser diameter.

Conclusion: The vascular network seems to be a good reference point during harvesting of the tendons of the semitendinosus and gracilis muscles, for facilitating graft harvesting.

Objetivos: Avaliar a prevalência da trama vascular adjacente à inserção da pata de ganso, para que possa ser usada como referência anatômica para facilitar a retirada de enxerto dos flexores na reconstrução artroscópica do ligamento cruzado anterior (LCA).

Métodos: Foram selecionados de forma aleatória 30 pacientes com rotura do LCA, os quais foram submetidos à reconstrução do LCA tendo como enxerto os tendões do semitendíneo (ST) e grácil (G). Durante a retirada dos tendões do ST e G, foi observada a presença ou ausência da referência anatômica.

Resultados: Todos os pacientes apresentaram trama vascular em menor ou maior diâmetro.

Conclusão: O uso da trama vascular durante retirada dos tendões do ST e G parece ser uma boa referência anatômica para facilitar a retirada do enxerto.

Keywords: Anterior cruciate ligament; Tendons/anatomy and histology; Tendons/transplantation.

Arrows show the tributaries of the vascular arch: (1) medial inferior genicular artery (superficial and deep branches); (2) lateral inferior genicular artery; (3) anterior tibial recurrent artery.
