Zusammenfassung:To evaluate a series of patients who underwent surgery for reconstruction of the anterior cruciate ligament with flexor tendons, by means of the anteromedial transportal technique using Rigidfix for femoral fixation, and to analyze the positioning of the pins by means of tomography. Thirty-two patients were included in the study. The clinical evaluation was done using the Lysholm, subjective IKDC and Rolimeter. All of them underwent computed tomography with 3D reconstruction in order to evaluate the entry point and positioning of the Rigidfix pins in relation to the joint cartilage of the lateral condyle of the femur. The mean Lysholm score obtained was 87.81 and the subjective IKDC was 83.72. Among the 32 patients evaluated, 43% returned to activities that were considered to be very vigorous, 9% vigorous, 37.5% moderate and 12.5% light. In 16 patients (50%), the distal entry point of the Rigidfix pin was located outside of the cartilage (extracartilage); in seven (21.87%), the distal pin injured the joint cartilage (intracartilage); and in nine (28.12%), it was at the border of the lateral condyle of the femur. The patients who underwent ACL reconstruction by means of the anteromedial transportal using the Rigidfix system presented satisfactory clinical results over the length of follow-up evaluated. However, the risk of lesions of the joint cartilage from the distal Rigidfix pin needs to be taken into consideration when the technique via an anteromedial portal is used. Further studies with larger numbers of patients and longer follow-up times should be conducted for better evaluation. Avaliar uma série de pacientes submetidos à cirurgia de reconstrução do ligamento cruzado anterior com tendões flexores pela técnica transportal anteromedial com o uso de Rigidfix para fixação femoral e analisar o posicionamento dos pinos por meio de tomografia. Foram incluídos no estudo 32 pacientes. A avaliação clínica foi feita com os escores de Lysholm, IKDC subjetivo e Rolimeter. Todos foram submetidos a tomografia computadorizada com reconstrução em 3D para avaliação do ponto de entrada e do posicionamento dos pinos do Rigidfix em relação à cartilagem articular do côndilo lateral do fêmur. A média do escore de Lysholm obtido foi de 87,81 e do IKDC subjetivo, de 83,72. Dos 32 pacientes avaliados, 43% retornaram a atividades consideradas muito vigorosas, 9% a vigorosas, 37,5% a moderadas e 12,5% a leves. Em 16 pacientes (50%), o ponto de entrada do pino distal do Rigidf
