A comparison between IPACK block and adductor canal block in post operative pain management
Two groups of patients between 40 and 60 yrs who are undergoing open wedge high tibeal osteotomy Group 1 will receive IPACK block with 15 ml Bupivacaine, immediately before spinal anaesthesia . Group 2 will receive adductor canal block ,also with 15 ml Bupivacaine. before spinal anaesthesia. register the time of first pain sensation and firs IV analgesic dose required in each group

Adductor canal block (ACB) is a popular peripheral nerve block that has been shown to decrease pain significantly and thereby opioid consumption with minimal effect on quadriceps function \[8\]. Though ACB provides analgesia to the peripatellar and intra-articular aspect of knee joint, it does not relieve posterior knee pain which is moderate to severe in intensity \[9, 10\]. The recent technique of an ultrasound (US)-guided local anesthetic infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) has shown to provide significant posterior knee analgesia without affecting the common peroneal nerve (CPN) \[11\]. We postulated that IPACK will provide better pain relief and improve knee function in the immediate postoperative period compared to ACB
the time of first pain sensation requiring analgesia
If intervention which is adductor canal block or lPACK block is effective in postoperative pain control that can decrease the lV analgesic agents
