Osteoarthritis can negatively impact sleep, as can surgery, making arthroplasty patients especially at risk for these ill effects both before and after surgery. Our study goals were to monitor sleep recovery and determine if perioperative melatonin could improve sleep quality compared to a placebo.\n                    <jats:italic>Methods<\/jats:italic>\n                    : From 2020 to 2023, a cohort of 48 primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients were randomized to melatonin (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a023) or placebo (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a025) for 7\u00a0weeks (1\u00a0week preoperatively, 6\u00a0weeks postoperatively). Patients were excluded if they already used sleep aids or had a sleep disorder. Sleep questionnaires collecting daily sleep and opioid data were electronically administered pre- and postoperatively up to 3\u00a0months. Generalized estimating equations were used to assess longitudinal sleep and opioid use.\n                    <jats:italic>Results<\/jats:italic>\n                    : THA patients in the melatonin group had significantly more hours of sleep than the controls, with the numbers available for this study (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0=\u00a00.009). However, this did not translate to improved sleep scores overall. There were no significant differences between the melatonin and control groups in the TKA patients. Sleep quality scores significantly improved over time for both hip and knee patients (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0=\u00a00.03). For THA patients, sleep scores did not return to baseline until 3\u00a0months postoperatively, whereas scores for TKA patients had improved beyond baseline by 2\u00a0weeks postoperatively.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    : Sleep disturbance is ubiquitous prior to surgery, and quality and quantity are negatively impacted after TJA surgery as well. TKA patients\u2019 sleep improved by 2\u00a0weeks, whereas THA patients did not improve till 3\u00a0months after surgery. The addition of perioperative melatonin led to more hours of sleep for THA patients but did not otherwise positively impact sleep quality, opioid use, or recovery in primary TJA patients.\n                  <\/jats:p>","DOI":"10.1051\/sicotj\/2026029","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T11:46:24Z","timestamp":1789386384000},"page":"53","source":"Crossref","is-referenced-by-count":0,"title":["Natural history of sleep before and after total joint arthroplasty is poor and unimproved by melatonin: A randomized controlled study"],"prefix":"10.1051","volume":"12","author":[{"given":"Alex","family":"Lancaster","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Utah","place":["USA"]},{"name":"Orthopedic Surgerym, St. Charles Health System","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brenna E.","family":"Blackburn","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Utah","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanna","family":"Loughmiller","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Utah","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Archibeck","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Utah","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy M.","family":"Gililland","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Utah","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucas A.","family":"Anderson","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Utah","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"1455","DOI":"10.2106\/JBJS.17.01617","volume":"100","author":"Sloan","year":"2018","journal-title":"J Bone Joint Surg Am"},{"key":"R2","doi-asserted-by":"crossref","first-page":"1938","DOI":"10.2106\/JBJS.20.02169","volume":"103","author":"Morrell","year":"2021","journal-title":"J Bone Joint Surg Am"},{"key":"R3","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1097\/ACO.0000000000000538","volume":"31","author":"Su","year":"2018","journal-title":"Curr Opin Anaesthesiol"},{"key":"R4","doi-asserted-by":"crossref","first-page":"e146","DOI":"10.1097\/BOT.0000000000000217","volume":"29","author":"Shulman","year":"2015","journal-title":"J Orthop Trauma"},{"key":"R5","doi-asserted-by":"crossref","first-page":"116","DOI":"10.1016\/j.jos.2018.07.019","volume":"24","author":"Long","year":"2019","journal-title":"J Orthop Sci"},{"key":"R6","doi-asserted-by":"crossref","first-page":"144","DOI":"10.3113\/JSOA.2019.0144","volume":"28","author":"Noback","year":"2019","journal-title":"J Surg Orthop Adv"},{"key":"R7","doi-asserted-by":"crossref","first-page":"1719","DOI":"10.1016\/j.euroneuro.2014.08.008","volume":"24","author":"Hansen","year":"2014","journal-title":"Eur Neuropsychopharmacol"},{"key":"R8","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1007\/s10865-005-9045-0","volume":"29","author":"Cremeans-Smith","year":"2006","journal-title":"J Behav Med"},{"key":"R9","doi-asserted-by":"crossref","first-page":"507","DOI":"10.1007\/s11892-014-0507-z","volume":"14","author":"Depner","year":"2014","journal-title":"Curr Diab Rep"},{"key":"R10","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1016\/j.bbi.2014.12.011","volume":"47","author":"Prather","year":"2015","journal-title":"Brain Behav Immun"},{"key":"R11","doi-asserted-by":"crossref","first-page":"e636","DOI":"10.3928\/01477447-20170411-01","volume":"40","author":"Manning","year":"2017","journal-title":"Orthopedics"},{"key":"R12","doi-asserted-by":"crossref","first-page":"769","DOI":"10.1093\/bja\/aes252","volume":"109","author":"Krenk","year":"2012","journal-title":"Br J Anaesth"},{"key":"R13","doi-asserted-by":"crossref","first-page":"500","DOI":"10.1097\/BOT.0000000000001276","volume":"32","author":"Swann","year":"2018","journal-title":"J Orthop Trauma"},{"key":"R14","unstructured":"Wurtman R.
