None of the patients had had previous knee surgery. All operations were performed according to the standard protocol. Daily mean pain numerical rating scale at rest (NRS-R) and during movement (NRS-M), requirement of extra pain control, complications related to pain control, and overall patient satisfaction in both groups were compared.<\/jats:p>\n <\/jats:sec>\n \n Results.<\/jats:title>\n Both groups were similar in terms of pain NRS-R and NRS-M, overall satisfaction, and length of hospital stay. Within each group, pain NRS-M score was significantly higher than pain NRS-R score. In the FNB group, 3 patients had dislodgement of the femoral catheter on day 1 and switched to PCA with intravenous morphine. Two of them had fair satisfaction. Patients in the PCA group had significantly more side-effects (nausea, vomiting, dizziness, and pruritis); 2 of the 5 patients with nausea and vomiting had fair satisfaction. No patients had any surgical complication.<\/jats:p>\n <\/jats:sec>\n \n Conclusion.<\/jats:title>\n Both FNC and PCA provide reliable pain control.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/230949901202000105","type":"journal-article","created":{"date-parts":[[2016,10,4]],"date-time":"2016-10-04T17:13:55Z","timestamp":1475601235000},"page":"23-26","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":16,"title":["Continuous Femoral Nerve Block versus Patient-Controlled Analgesia following Total Knee Arthroplasty"],"prefix":"10.1177","volume":"20","author":[{"given":"Fu-Yuen","family":"Ng","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Queen Mary Hospital, The University of Hong Kong, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwong-Yuen","family":"Chiu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Queen Mary Hospital, The University of Hong Kong, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun Hoi","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Queen Mary Hospital, The University of Hong Kong, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kwok-Fu Jacobus","family":"Ng","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology, Queen Mary Hospital, The University of Hong Kong, Hong Kong"},{"name":"Department of Pharmacology and Pharmacy, The University of Hong Kong, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,4,1]]},"reference":[{"key":"bibr1-230949901202000105","doi-asserted-by":"crossref","first-page":"130","DOI":"10.1213\/00000539-200201000-00025","volume":"94","author":"Strassels SA","year":"2002","journal-title":"Anesth Analg"},{"key":"bibr2-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2007.10.004"},{"key":"bibr3-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-0728-7"},{"key":"bibr4-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1213\/00000539-198805000-00007"},{"key":"bibr5-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1007\/s004020050407"},{"key":"bibr6-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1016\/S0883-5403(08)80052-6"},{"key":"bibr7-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1097\/00115550-199823020-00005"},{"key":"bibr8-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1054\/arth.2001.23622"},{"key":"bibr9-230949901202000105","first-page":"292","volume":"21","author":"Hirst GC","year":"1996","journal-title":"Reg Anesth"},{"key":"bibr10-230949901202000105","doi-asserted-by":"publisher","DOI":"10.1177\/230949900801600324"}],"container-title":["Journal of Orthopaedic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/230949901202000105","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/230949901202000105","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T00:17:57Z","timestamp":1777594677000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/230949901202000105"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,4]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2012,4]]}},"alternative-id":["10.1177\/230949901202000105"],"URL":"https:\/\/doi.org\/10.1177\/230949901202000105","relation":{},"ISSN":["1022-5536","2309-4990"],"issn-type":[{"value":"1022-5536","type":"print"},{"value":"2309-4990","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,4]]}}}
