ABSTRACT
INTRODUCTION: The tearing of the anterior cruciate ligament (ACL) is one of the most common type of knee injury. Current evidence show that there are specific predictors for postoperative success in ACL injuries, but there is a limited number of studies on preoperative rehabilitation. Therefore, the goals of this review were to emphasize physiotherapy approaches to the preoperative period and to verify its effectiveness at the time the athlete returns to sport. METHOD: We conducted a systematic search in these databases: Medline, Scielo, Lilacs, CINAHL, Web of Science, PeDro and Cochrane Library. RESULTS: Our searches identified 553 occurences; of these, 511 titles and abstracts underwent triage after removal of duplicates. We identified 120 full texts for a stricter screening, amongst them, three studies included in the review for complying with the elegibility criteria. CONCLUSION: Physiotherapic preoperative treatment exhibits weak evidence for strength gains and pain relief, as well as strong evidence of functional improvement compared to the control group. These results were reported 4 months after the ACLR, in average.
