Smith JRH, Belk JW, Kraeutler MJ, et al. - A systematically review and meta-analysis were conducted to correlate the adductor canal block (ACB) to the femoral nerve block (FNB) following primary anterior cruciate ligament reconstruction (ACLR) in terms of early postoperative analgesic requirements and postoperative quadriceps strength. Researchers carried out to search PubMed, the Cochrane Library, and Embase up to August 2019 to identify randomized controlled trials which compared postoperative pain and functional outcomes in patients following primary ACLR with ACB versus FNB. They examined individuals based on analgesic consumption and quadriceps muscle strength. They investigated study quality and risk of bias with the Modified Coleman Methodology Score and Cochrane risk-of-bias tool respectively. The ACB may serve similar analgesic needs in patients undergoing ACLR and the included studies imply a potential advantage in preserving muscle strength at short-term (24-48 hours) follow-up  when compared to FNB. Nevertheless, the differences in muscle strength evaluations between studies do not permit for strong conclusions.
