| Popis: | Background and objective Currently, there is no stablished pre-operative model that helps the orthopaedic surgeon predict the final graft diameter in anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to determine whether there is a correlation between semitendinosus (ST) and gracilis (GT) cross-sectional area (CSA) evaluated pre-operatively in mm2 using magnetic resonance imaging (MRI) and the final intra-operative ST–GT autograft diameter in mm2. Methods A retrospective study was designed, 89 patients undergoing ACLR with hamstring autograft participated. We analysed ST-CSA (mm2) and GT-CSA (mm2) using pre-operative MRI, intra-operative autograft diameter, age, sex, side of the injury, weight, height and body mass index (BMI). Results A moderate–strong correlation was identified between final autograft diameter and ST–GT CSA in MRI (Pearson correlation coefficient .6911 p Conclusions Preoperative determinations of ST-CSA and GT-CSA (mm2) using MRI correlate with the final autograft diameter. This method represents a reliable and reproducible model to predict the hamstring autograft diameter in ACLR. Level of evidence Retrospective cohort study, level IV. Clinical relevance A review of the available literature reveals a higher risk of ACL failure or re-rupture if the graft is smaller than 8 mm in diameter. Despite being an important factor there is no established pre-operative model that predicts the final graft diameter. Knowing beforehand the possibilities of obtaining a hamstring autograft with a diameter greater than or equal to 8 mm would help the orthopaedic surgeon to better plan the surgery and to anticipate the need for other graft options (such as bone-patellar-tendon-bone autograft or allografts, amongst other alternatives). |
