“…Walden and colleagues (2006) showed that 50 % of athletes with a history of ACL injury and subsequent reconstruction go on to suffer an overuse knee injury such as bursitis, tendinitis or patellofemoral pain syndrome. This suggests greater care should be taken from early to late stage rehabilitation to ensure successful recovery before players return to competition in their respective sports (Walden et al, 2015). It may be that after ACLR, persistent neuromuscular and biomechanical risk factors occur which render athletes at greater risk of future re-injury (Alentorn-Geli et al, 2009a;Hewett et al, 1999;Hewett et al, 2006;Mandelbaum et al, 2005).…”
