This study aimed to evaluate the post-operative analgesic efficacy and safety of ultrasound-guided adductor canal block (ACB) compared to conventional intravenous morphine analgesia.\n\nMaterials and Methods: This randomized, controlled, interventional study was conducted in the post-anesthesia care unit (PACU) of the Department of Anesthesiology in an Indian Hospital. Eighty adult patients (American Society of Anesthesiologists [ASA] I\u2013II) undergoing unilateral knee arthroscopy under general anesthesia were randomly divided into two groups: Group M received intravenous morphine (0.1 mg\/kg) before incision, and Group B received an ultrasound-guided ACB with 15 mL of 0.25% bupivacaine before extubation. Post-operative analgesic efficacy was assessed by the requirement of rescue analgesia and the time to achieve a Visual Analog Score (VAS) &lt;3. Adverse effects and antiemetic requirements were also recorded. Statistical analysis was performed using the Statistical Package for Social Sciences version 17.0, and a P &lt; 0.05 was considered significant.\n\nResults: Both groups were comparable in terms of age, sex, ASA physical status, and pre-operative vitals (P &gt; 0.05). Rescue analgesia in the PACU was required in 47.5% of patients in Group M and 10.0% in Group B (P &lt; 0.001). The mean time to achieve VAS &lt;3 was significantly shorter in Group B (11.00 \u00b1 3.79 min) compared to Group M (16.00 \u00b1 9.00 min) (P = 0.002). The requirement of antiemetic medication was lower in Group B (20.0%) than in Group M (42.5%) (P = 0.030). No adverse events were reported in either group.\n\nConclusion: Ultrasound-guided ACB provides superior post-operative analgesia, faster pain relief, and fewer side effects compared to intravenous morphine in patients undergoing knee arthroscopy.\n\nKeywords: Adductor canal block, knee arthroscopy, post-operative analgesia, morphine, ultrasound-guided block.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i01.6682","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T02:44:16Z","timestamp":1768358656000},"page":"288-293","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Post-operative Analgesic Efficacy of Adductor Canal Block Compared to Conventional Intravenous Analgesics in Knee Arthroscopy Surgery"],"prefix":"10.13107","volume":"16","author":[{"name":"Department of Anaesthesia, SRVS Medical College, Shivpuri, Madhya Pradesh, India,","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Priyanka","family":"Gupta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohan Babu","family":"Nema","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Anaesthesia, MGM Medical College, Indore, Madhya Pradesh, India,","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arvind","family":"Karoria","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Orthopaedics, SRVS Medical College, Shivpuri, Madhya Pradesh, India,","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vaibhav","family":"Gupta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Anaesthesia Specialist, District Hospital, Shivpuri, Madhya Pradesh, India,","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parul","family":"Nema","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Pathology, SRVS Medical College, Shivpuri, Madhya Pradesh, India,","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishnu Kumar","family":"Gupta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Community Medicine, SRVS Medical College, Shivpuri, Madhya Pradesh, India.","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T02:44:16Z","timestamp":1768358656000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/01\/evaluation-of-post-operative-analgesic-efficacy-of-adductor-canal-block-compared-to-conventional-intravenous-analgesics-in-knee-arthroscopy-surgery\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i01.6682","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
