“…Physical rehabilitation lasting up to 12 months is recommended after ACLR to restore function and stability to the knee (Adams et al, 2012;Zadro & Pappas, 2018), and to optimise post-surgical outcomes (Grindem, Granan, et al, 2015). Recent evidence suggests people may not be completing sufficient post-ACLR rehabilitation before returning to pre-injury activities Grindem, Arundale, & Ardern, 2018). Irrespective of how an ACL injury is managed, a significant percentage of people do not return to pre-injury activity levels (Ardern, Taylor, Feller, & Webster, 2014;Øiestad, Holm, & Risberg, 2018;Webster & Feller, 2018), or they suffer a subsequent ACL injury (Crawford, Waterman, & Lubowitz, 2013;Lai, Ardern, Feller, & Webster, 2017;Wright, Magnussen, Dunn, & Spindler, 2011).…”
