After written informed consent, patients will be allocated to one of the groups, following a computer-generated list of randomization.\n\nPrior to surgery, all patients will have an adductor canal block with 20ml of ropivacaine 0.75%. In group TIBIAL the patient will receive in addition a selective tibial nerve block with 5 ml of ropivacaine 0.75%. In group IPACK the patient will receive in addition an IPACK with 20ml of ropivacaine 0.2%. In both groups, patients will have the surgery under general anaesthesia with a multimodal analgesic regimen inclusive of iv dexamethasone 8 mg, iv magnesium sulfate 40 mg.kg-1, iv ketorolac 30 mg, and iv acetaminophen 1000 mg.\n\nAfter surgery, all patients will be prescribed an iv patient-controlled analgesia (PCA) of morphine (boluses of 2 mg available every 10 min, maximum of 40 mg every 4 hours) along with oral acetaminophen (1000 mg every 6 h) and oral ibuprofen (400 mg every 8 hours). Oral ondansetron 4 mg every 8 hours will be available on request in case of nausea or vomiting.\n\nThe primary outcome will be the cumulative iv morphine consumption at 24 h postoperatively. Secondary outcomes will include pain- and functional-related outcomes. Pain-related outcomes include cumulative morphine consumption at 2h and 48h postoperatively, rest and dynamic pain scores and rate of PONV at 2 h, 24 h and 48 h postoperatively. Early functional-related outcomes include range of motion, strength and walking distance at 24 h and 48 h postoperatively. Late functional-related outcomes include range of motion, strength, hop distance, agility test, Y balance test, Anterior Cruciate Ligament Return to Sport After Injury Scale (ACL-RSI) and International Knee Documentation Committee Scale (IKDC) at 4 and 8 months postoperatively.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* ASA score I-III\n* 18 years or older\n* Scheduled for elective primary ACL reconstruction\n* Signature of consent form\n\nExclusion Criteria:\n\n* Refusal or inability for informed consent\n* Known allergies to ropivacaine, acetaminophen, ibuprofen, ketorolac, morphine, sufentanyl, ondansetron or dexamethason\n* Secondary surgical revision\n* Opioid treatment such as morphine, hydrocodone, hydromorphone, tramadol, methadone, fentanyl, buprenorphine or codeine\n* Bleeding diathesis\n* Neurological deficit\n* Known renal insufficiency (eGFR \\<45 ml/min)\n* Known hepatic insufficiency (Child score B or C)\n* Pregnancy or lactating\n* Alcohol abuse'}, 'identificationModule': {'nctId': 'NCT05303233', 'acronym': 'TIPACK', 'briefTitle': 'IPACK or Selective Tibial Nerve Block for ACL Reconstruction With an Adductor Canal Block', 'organization': {'class': 'OTHER', 'fullName': 'Centre Hospitalier Universitaire Vaudois'}, 'officialTitle': 'Analgesic Efficacy of IPACK Versus Selective Tibial Nerve Block in Patients Scheduled for Anterior Cruciate Ligament Reconstruction Under General Anaesthesia With an Adductor Canal Block: a Randomized Controlled Double-blinded Trial', 'orgStudyIdInfo': {'id': 'CER-VD 2021-02474'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'TIBIAL group', 'description': 'All patients allocated to the TIBIAL group will receive an adductor canal block with 20ml of ropivacaine 0.75% and a selective tibial nerve block with 5 ml of ropivacaine 0.75% prior to surgery,', 'interventionNames': ['Procedure: Selective tibial nerve block']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'IPACK group', 'description': 'All patients allocated to the IPACK group will receive an adductor canal block with 20ml of ropivacaine 0.75% and an IPACK with 20ml of ropivacaine 0.2% prior to surgery.', 'interventionNames': ['Procedure: IPACK']}], 'interventions': [{'name': 'Selective tibial nerve block', 'type': 'PROCEDURE', 'description': 'The selective tibial nerve block will be performed on the popliteal crease following sterilization of the area.
