Perineural Dexamethasone in the Adductor Canal Block

Postoperative pain management in total knee arthroplasty (TKA) surgery is a real challenge for the anesthesiologist. Effective pain control must be provided while preserving the mobility to ensure early rehabilitation. The adductor canal block is an effective way to induce sensory block without motor block. However, the major disadvantage of this block is the duration of sensory block which may be insufficient for postoperative pain management in TKA surgery. Many studies have focused on finding molecules that can prolong sensory block without the need for a perineural catheter and dexamethasone is among the most studied molecules(1, 2). Hence, our study aims to evaluate the added value of perineural dexamethasone in the adductor canal block in TKA surgery. \[
