The majority of studies that compared femoral nerve blocks with placebo or conventional pain management modalities failed to demonstrate a significant reduction in length of stay. All studies that compared femoral nerve blocks with epidurals found no significant difference in length of stay. Only half of the studies comparing local anaesthetic techniques to placebo or conventional pain management methods found a significant reduction in length of stay.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> The reporting quality has specific deficiencies in the areas of sample size calculation, randomization whilst there was under\u2010reporting of blinding. Regional and local anaesthetic techniques have not demonstrated a clear reduction in hospital length of stay. Epidurals and femoral nerve blocks have similar impacts on length of stay.<\/jats:p>","DOI":"10.1111\/j.1445-2197.2011.05991.x","type":"journal-article","created":{"date-parts":[[2012,2,3]],"date-time":"2012-02-03T09:03:03Z","timestamp":1328259783000},"page":"207-214","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Impact of regional and local anaesthetics on length of stay in knee arthroplasty"],"prefix":"10.1111","volume":"82","author":[{"given":"Conor","family":"Crowley","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle M.","family":"Dowsey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colm","family":"Quinn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Barrington","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter F.
