Have you looked in PubMed or Medline databases? Links can be found here http://libguides.unomaha.edu/content.php?pid=419246&sid=3427056#12253702 PubMed has more full text articles, such as this one: http://www.ncbi.nlm.nih.gov/pubmed/23126312
I used the search terms "pain management" AND "knee replacement" AND "trial" to see what pops up. Reading through the abstracts will help you see if it's an article from an actual trial/study done (a primary source), or if it's merely evaluating studies (a secondary source). If your results aren't quite hitting the mark, play with the search terms by swapping management for control or adding in elderly or women.
Also, you will have to hunt for links like "Free PMC article" or "Get PDF" to get past the absracts. Unfortunately, they can be overlooked with all the text and info on the page. If you run into problems, feel free to contact us. Our health librarian is Melissa Cast-Brede at 554-3130 and firstname.lastname@example.org
