  "abstract": "Soffin et al decry the ‘unwarranted variation’ in nerve blocks,1 as reported in a recent study of anterior cruciate ligament (ACL) reconstruction in paediatric patients.2 In this study, 86% of patients received 1 of 22 different nerve blocks, but outcomes appear to be no different. What about the 72 patients (14%) who did not receive a nerve block—what were their outcomes? This group is larger than the one receiving a single-shot femoral nerve block. Given the reported number of patients with prolonged weakness or numbness, is a nerve block routinely indicated at all?",
