Summary
Patient suffer from moderate posterior knee pain after TKA despite injection of local
anesthetic around the femoral or saphenous nerves. Indeed, the posterior part of the knee is
innervated by the sciatic nerve. This nerve is not routinely blocked as clinicians fear to
produce a motor block of the leg that might impair the postoperative assessment. An analgesic
alternative is the infiltration of the knee with local anesthetics performed by the surgeon.
Recently a trial(1) demonstrated that a selective tibial nerve block provides an effective
analgesia without a motor blockage when compared with a sciatic nerve block. The objective of
this randomized controlled double-blinded trial is to assess whether a tibial nerve block is
more effective for the postoperative pain than local infiltration analgesia when there are
combined with an adductor canal block, without decreasing the functional parameters.
