Anterior cruciate ligament reconstruction (ACLR) frequently results in quadriceps atrophy. The present study investigated the effect of ACLR on the muscle thickness of the different constituent muscles of the quadriceps and circulating biomarkers related to muscle atrophy and hypertrophy. Fourteen subjects underwent anterior cruciate ligament reconstruction following injury. Quadriceps muscle thicknesses were measured using ultrasound, and circulating biomarkers in the blood were measured using enzyme-linked immunosorbent assays (ELISAs) at the preoperative visit (PRE) and at two postoperative visits (PO1, PO2) in the early stages post-surgery. Differences between time points were analyzed using one-way repeated measures analysis of variance (ANOVA) tests. The most important finding was that severe muscle atrophy occurred in the vastus intermedius (VI) after ACLR (PRE: 20.45 ± 6.82 mm, PO1: 16.05 ± 6.13 mm, PO2: 13.18 ± 4.7 mm, F = 59.0, p < 0.001). Furthermore, the myostatin level was slightly increased, and IGF-1 was significantly reduced throughout the entire period. Therefore, we suggest that inducing selective hypertrophy in the vastus intermedius during the process of rehabilitation would be important for athletes and individuals who engage in explosive sports. Moreover, inhibiting myostatin level increases and maintaining IGF-1 levels in the early phase of recovery after ACLR to prevent muscle atrophy may provide a pharmaceutical option for rehabilitation after anterior cruciate ligament injury.

Blood flow restriction is a physical therapy technique that consists of promoting increased strength and muscle hypertrophy, similar to protocols with high loads. It can be used in the prevention and rehabilitation of injuries, health promotion and improvement in sports performance, as in the postoperative period of anterior cruciate ligament reconstruction, accelerating functional recovery. To identify the effects of blood flow restriction in patients undergoing anterior cruciate ligament reconstruction. Through a systematic review of the literature, randomized clinical trials were selected according to the highest PEDro score. The search involved the PEDro database, PubMed, using the following terms: bloodflow restriction, anterior cruciate ligament, anteriorcruciate ligament injury and BFR exercise, published between 2000 and 2021. Six RCTs were selected: three did not demonstrate benefits in relation to atrophy, strength, volume and activation of the quadriceps muscle during blood flow restriction, when used through isometric, concentric and eccentric exercises, with progressive loads or without loads. In two other RCTs, there were positive results in relation to the aforementioned parameters, where freeexercises were performed, with body resistance and sessions with occlusive stimuli and occlusion release. Finally, one of the RCTs showed equal improvement in both groups in quadriceps hypertrophy and strength; and regarding the use of flow restriction inone of the groups, there was a reduction in joint pain and effusion. Blood flow restriction has shown contradictory results in relation to atrophy, decreased pain, effusion and asymmetry of the quadriceps muscle in patients undergoing anterior cruciate ligament reconstruction.
