Smith JRH, Belk JW, Kraeutler MJ, et al. - A systematically review was conducted to correlate the adductor canal block (ACB) with the femoral nerve block (FNB) following primary anterior cruciate ligament reconstruction (ACLR) in terms of early postoperative analgesic requirements and postoperative quadriceps strength. Researchers conducted this review by searching PubMed, the Cochrane Library, and Embase up to August 2019 to distinguished randomized controlled trials that compared postoperative pain and functional outcomes in patients following primary ACLR with ACB vs FNB. The search phrase applied was: adductor canal femoral nerve anterior cruciate ligament. Individuals were analyzed based on analgesic consumption and quadriceps muscle strength. They assessed study quality and risk of bias with the Modified Coleman Methodology Score and Cochrane risk-of-bias tool respectively. When compared with FNB, the ACB may provide similar analgesic requirements, and the included studies suggest a potential advantage in preserving muscle strength at short-term (24-48 hours) follow-up in patients undergoing ACLR. Nevertheless, the differences in muscle strength evaluations between studies do not permit for strong conclusions.
