BACKGROUND Continuous epidural analgesia is the gold standard for postoperative analgesia for lower limb surgeries. But it needs strict patient monitoring as it can cause hypotension, opioid induced bradycardia, delayed mobility due to dense motor block, leading to long hospital stay which in turn makes the patient prone for nosocomial infections and DVT. Other modes of analgesia include femoral nerve block but this leads to quadriceps weakness leading to delayed mobility and patient discharge. METHODS We describe two different sites of injections of drug into adductor canal that is upper adductor canal and lower adductor canal to evaluate adequate analgesia. 100 patients posted for unilateral TKR was selected randomly. Block was performed post-operatively. Group A patients received distal adductor canal block and group B patients received proximal adductor canal block. Both the groups of patients received 0.25% bupivacaine 40 ml. Painless time after giving block was noted by the ICU staff who was blinded and the total amount of analgesia required in 24 hours was noted along with the VAS score at 12 Hrs and 24 Hrs after surgery. RESULTS Lower adductor canal block provided better analgesia with a VAS score significantly less at 12 hrs and 24 hrs and also the painless time in hours was significantly more in group A patients. We also noticed that the analgesic requirement in group A patients was less compared to group B at 0.01 level 99% sign. CONCLUSIONS Lower adductor canal block provided better analgesic outcome in patients undergoing unilateral TKR in the acute postoperative period.
