Purpose The aim of the study was to compare three different procedures performed by the same surgeon: monobundle patellar tendon reconstruction (bone-patellar tendonbone, BPTB), double-bundle hamstring reconstruction (DBH) and mono-bundle patellar tendon combined with extraarticular reconstruction (Lemaire) (BPTB + L). Methods A total of 75 patients (25 in each group) were evaluated at a mean follow-up of 25 months. Laxity was assessed pre-and post-operatively with Telos™ stress radiographs (15 kg). The amount of anterior tibial translation (ATT) corrected by the surgery was quantified. Secondary outcomes were International Knee Documentation Committee (IKDC) scores, pivot shift grading, pain complaints, sensory deficits, subsequent surgical procedures, return to sports and patients' ability to kneel or squat on their affected knee. Results Absolute correction of ATT for the internal compartment was not statistically significant [analysis of variance (ANOVA), p=0.377]. For the external compartment BPTB + L (8.2 mm) showed superiority over DBH (5.6 mm) and BPTB (4
