Brief Summary: Pain after anterior cruciate ligament reconstruction with autologous hamstring graft can be attributed to both arthroscopic surgery and the graft donor site Many methods are available to provide postoperative analgesia for patients undergoing total knee arthroplasty but it is unclear how they compare with each other The extent to which the two techniques anterior division obturator nerve block vs peritendinous hamstring injection may benefit the patients in terms of overall analgesia and specifically the autograft site analgesia needs evaluation
Detailed Description: In induction room standard anesthesia monitors including Electrocardiogram Non Invasive Blood Pressure and pulse oximeter will be connected Baseline parameters such as mean arterial pressure heart rate and oxygen saturation will be recorded An intravenous cannula of 18-gauge will be secured and intravenous lactated Ringer will be started for all patients The patients will be premedicated with Midazolam 002 mgkg fentanyl 50-100 μg IV titrated to effect Granisetron 1 mg undiluted Intravenous push over 30 seconds and Proton pump inhibitor 40 mg Patients will be placed in the supine position with the operative leg externally rotated Asepsis will be achieved using chlorhexidine 2 in alcohol The skin at block sites will be subsequently infiltrated with lidocaine 2

In group C n26 every patient will receive unilateral adductor canal block alone a pre-procedural scan using a 5 cm 7-13 MHz high-frequency linear transducer will be performed to identify the location of the descending genicular artery arising from the superficial femoral artery The finding of this vascular landmark is known to demark the exit and subsequent bifurcation of the saphenous nerve from the adductor canal just distal to the discontinuation of the vaso-adductor membrane The injection point for the ACB will be 2 cm proximal to this landmark along the sartorius muscle A 21-gauge 90 mm needle will pass in-plane in an anterolateral to posteromedial direction through the sartorius muscle Once the needle tip location is confirmed by hydro-location using dextrose 5 1-2 ml to be lateral to the femoral artery but within the adductor canal bupivacaine 025 20 ml will be injected after negative aspiration for blood

In group H n26 every patient will receive unilateral peri-hamstring injection combined to adductor canal block After the completion of the Adductor canal block the transducer will be moved further posteriorly around the thigh The same needle will be redirected in a steeper posteromedial direction towards the fascial plane between the sartorius and gracilis muscle Once the needle tip is confirmed to be deep to sartorius but superficial to gracilis bupivacaine 025 75 ml will be injected superficially to the deep fascia of the muscle sheath to achieve free spread around the anterior surface of the muscle contained within the fascial compartment as the muscle was viewed in short axis on ultrasound The needle will then be advanced further posteriorly towards the fascial planes between the semimembranosus and semitendinosus and an additional bupivacaine 025 75 ml will be similarly injected to achieve spread around the anterior aspect of the semitendinosus muscle superficial to its deep fascia

In group O n26 every patient will receive unilateral anterior obturator nerve block combined to adductor canal block The anterior branch of the obturator nerve is seen in the proximal thigh medial to the femoral vessels between the adductor longus and adductor brevis below the inguinal crease The same 21-gauge 90 mm needle will be directed through the adductor longus in an out of plane technique A small volume of dextrose 5 1-2 ml will be injected to ensure the needle tip is positioned between the two muscles After negative aspiration bupivacaine 025 10 ml will be injected in this muscle plane to surround the anterior division of obturator nerve
