We sought to describe six ACLR registry cohorts to understand variation across countries.Methods Five European registries and one US registry participated. For each registry, all primary ACLR registered between registry establishment through 31December 2014 were identified. Descriptive statistics included frequencies, proportions, medians and IQRs. Revision incidence rates following primary ACLR were computed.Results 101 125 ACLR were included: 21 820 in Denmark, 300 in Luxembourg, 17 556 in Norway, 30 422 in Sweden, 2972 in the UK and 28 055 in the US. In all six cohorts, males (range: 56.8%–72.4%) and soccer injuries (range: 14.1%–42.3%) were most common. European countries mostly used autografts (range: 93.7%–99.7%); allograft was most common in the US (39.9%). Interference screw was the most frequent femoral fixation in Luxembourg and the US (84.8% and 42.9%), and suspensory fixation was more frequent in the other countries (range: 43.9%–75.5%). Interference was the most frequent tibial fixation type in all six cohorts (range: 64.8%–98.2%). Three-year cumulative revision probabilities ranged from 2.8% to 3.7%.Conclusions Similarities in patient demographics and injury activity were observed between all cohorts of ACLR. However, graft and fixation choices differed. Revision rates were low. This work, including >100 000 ACLR, is the most comprehensive international description of contemporary practice to date. ER -
