CORR Insights®: Report of the Clinical and Functional Primary Outcomes in Men of the ACL-SPORTS Trial: Similar Outcomes in Men Receiving Secondary Prevention With and Without Perturbation Training 1 and 2 Years After ACL Reconstruction

R eturning to sport is a key determinant of longer-term quality of life after ACL reconstruction [5]. Although most patients expect to return to preinjury sport after ACL reconstruction [4], only 60% of nonelite athletes fulfil this expectation [2]. Of further concern, one in four young athletes who return to sport suffer a graft rupture or contralateral ACL rupture [14]. Unfortunately, people who have a revision ACL reconstruction or rupture their contralateral ACL are likely to experience persistent knee difficulties and poor quality of life [6, 10]. It is possible that many rehabilitation programs are falling short in the later stages when it comes to physically and psychologically preparing an ACL reconstructed individual to return to sport. A primary aim of ACL rehabilitation is to restore physical knee deficits, yet restoration of knee deficits does not correspond to a successful return to sporting performance or prevention of further knee injury. Evidence is limited surrounding predictors of successful rehabilitation, return to sport, and reinjury after ACL reconstruction [12]. The study by Arundale and colleagues, explored the benefit of adding perturbation training to a high level rehabilitation program designed to facilitate return to preinjury sport This CORR Insights is a commentary on the article ‘‘Report of the Clinical and Functional Primary Outcomes in Men of the ACLSPORTS Trial: Similar Outcomes in Men Receiving Secondary Prevention With and Without Perturbation Training 1 and 2 Years After ACL Reconstruction by Arundale and colleagues available at: DOI: 10.1007/ s11999-017-5280-2.
