This is a study that was published Oct last year, 2016 in the AJSM. It has been made open-access just recently on PMC.
“Rehabilitation before anterior cruciate ligament (ACL) reconstruction (ACLR) is effective at improving postoperative outcomes at least in the short term. Less is known about the effects of preoperative rehabilitation on functional outcomes and return-to-sport (RTS) rates 2 years after reconstruction.”
“After adjusting for baseline IKDC and KOOS scores, the DOC patients showed significant and clinically meaningful differences in IKDC and KOOS scores 2 years after ACLR. There was a significantly higher (P< .001) percentage of DOC patients returning to preinjury sports (72%) compared with those in the MOON cohort (63%).”
“The cohort treated with additional preoperative rehabilitation consisting of progressive strengthening and neuromuscular training, followed by a criterion-based postoperative rehabilitation program, had greater functional outcomes and RTS rates 2 years after ACLR. Preoperative rehabilitation should be considered as an addition to the standard of care to maximize functional outcomes after ACLR.”
I guess it is no surprise that those with extended pre-op rehab showed better outcomes than those who did not, even at 2 years follow up. However there wasn’t a large difference in the RTS rates between the two groups, 72% compared to 63%.
