ResumoObjetivoAvaliar se a retirada dos dois tendões flexores (semitendíneo [ST] e grácil [GC]) tem o mesmo índice de lesão nervosa que a retirada isolada do tendão ST usado como enxerto triplo.MétodosFoi avaliada a alteração de sensibilidade relacionada à lesão do ramo infrapatelar do nervo safeno em 110 pacientes seis meses após serem submetidos à reconstrução do LCA com o uso dos tendões flexores, dividido num grupo no qual se usou somente o ST e outro com o ST e o GC.ResultadosO grupo no qual se usou somente o ST como enxerto apresentou um índice de lesão nervosa de 36,1% e no grupo com os tendões ST e GC 58,1% dos pacientes tiveram alteração da sensibilidade. Na avaliação geral de todos os pacientes o índice de lesão nervosa foi de 50,9%.ConclusãoA retirada do ST isolado e usado de forma tripla é uma opção viável na reconstrução do LCA e pode ocasionar um menor número de lesão nervosa relacionada a ramos do nervo safeno.AbstractObjectiveThe aim of this study was to assess whether harvesting of two hamstring tendons (semitendinosus and gracilis) has the same rate of nerve injury as harvesting of the semitendinosus tendon alone, used as a triple graft.MethodsChanges in sensitivity relating to injury of the infrapatellar branch of the saphenous nerve were evaluated in 110 patients six months after they underwent anterior cruciate ligament (ACL) reconstruction using hamstring tendons. They were divided into two groups: one in which only the semitendinosus was used and the other, the semitendinosus and gracilis.ResultsThe group in which only the semitendinosus was used as a graft presented a nerve injury rate of 36.1%. In the group in which the semitendinosus and gracilis tendons were used, 58.1% of the patients presented altered sensitivity. In the general assessment on all the patients, the nerve injury rate was 50.9%.ConclusionHarvesting the semitendinosus alone and using it in triple form is a viable option for ACL reconstruction and may give rise to fewer nerve injuries relating to branches of the saphenous nerve
