Figure 2 Sequential responses to up-and-down concentrations of ropivacaine for adductor canal block. (A) The sequential responses to up-and-down concentrations of ropivacaine in Group R. (B) The sequential responses to up-and-down concentrations of ropivacaine in Group RD. Empty squares indicate a positive response (ie, complete sensory block), and black squares indicate a negative response (ie, incomplete sensory block).
