"Patients scheduled to undergo ACLR via a single surgeon (R.R.), with or without concomitant meniscal pathology, were recruited for the study. This parallel group study randomized patients to either an HT (n = 57) or QT (n = 59) autograft construct using a “random number sequence generator.” The random number sequence was maintained by an independent researcher, with each group randomization released upon recruitment and consent. Patients were included if they were aged 16 to 50 years and qualified for ACLR based on clinical examination and magnetic resonance imaging. The exclusion criteria were as follows: unable or unwilling to sign the patient informed consent specific to this study; a body mass index of ≥40; revision or multiligamentous reconstruction; presenting with significant articular cartilage pathology that likely required concomitant surgical intervention; and being treated for a psychiatric disorder, senile dementia, Alzheimer disease, or the presence of alcohol or substance abuse. Ethical approval was provided by the Hollywood Private Hospital (HPH541) Human Research Ethics Committee, and the trial was conducted according to the Declaration of Helsinki. The trial was registered in the Australian New Zealand Clinical Trials Registry (ANZCTR - ACTRN126180015 20224p).
