We read with interest the study conducted by Abdallah et al.1  comparing single femoral and adductor canal (AC) blocks on quadriceps function in patients undergoing anterior cruciate ligament (ACL) reconstruction. Although their design was complex, the authors seem to have not considered some fundamental principles of peripheral nerve block research. This unfortunately may limit the clinical usefulness of the authors’ findings.
Finally, it was established 20 yr ago that the clinical benefits of a femoral block performed for knee surgery varies with the type of knee surgery and expected associated pain.7  This is especially important when considering (as appropriately acknowledged by the authors) that only two thirds of the patients included in this study underwent an ACL repair using a hamstring tendon (that being the type of ACL repair demonstrated to really benefit from a femoral nerve block).
