We analyzed data from the US Health and Retirement Study (1998-2010) on individuals aged 45 or older with no prior receipt of JR. We used logistic regression to analyze the probability of receiving knee or hip replacement by gender and age (&lt;65, 65+). We estimated the effect of demographic, health needs, economic, and familial support variables on the rate of JR. We found that being married\/partnered with a healthy spouse\/partner is positively associated with JR utilization in both age groups (65+ group OR: 1.327 and &lt;65 group OR: 1.476). While this finding holds for men, it is not statistically significant for women. Among women younger than 65, having children younger than 18 lowers the odds (OR: 0.201) and caring for grandchildren increases the odds (1.364) of having a JR. Finally, elderly women who report availability of household assistance from a child have higher odds of receiving a JR as compared with elderly women without a child who could assist (OR: 1.297). No effect of available support from children was observed for those below 65 years old and elderly men. Our results show that intrafamily dynamics and familial support are important determinants of JR; however, their effects vary by gender and age. Establishing appropriate support mechanisms could increase access to cost-effective JR among patients in need of surgery.<\/jats:p>","DOI":"10.1177\/0046958019837438","type":"journal-article","created":{"date-parts":[[2019,4,5]],"date-time":"2019-04-05T03:13:26Z","timestamp":1554434006000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Determinants of Hip and Knee Replacement: The Role of Social Support and Family Dynamics"],"prefix":"10.1177","volume":"56","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4212-5795","authenticated-orcid":false,"given":"Berna","family":"Demiralp","sequence":"first","affiliation":[{"name":"KNG Health Consulting, LLC, Rockville, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lane","family":"Koenig","sequence":"additional","affiliation":[{"name":"KNG Health Consulting, LLC, Rockville, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9439-3412","authenticated-orcid":false,"given":"Jennifer T.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"KNG Health Consulting, LLC, Rockville, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel A.","family":"Soltoff","sequence":"additional","affiliation":[{"name":"KNG Health Consulting, LLC, Rockville, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,4,5]]},"reference":[{"key":"bibr1-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1001\/archinternmed.2009.136"},{"key":"bibr2-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2011.09.030"},{"key":"bibr3-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1996.03530350040032"},{"key":"bibr4-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1016\/j.jval.2012.10.020"},{"key":"bibr5-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1177\/0141076813489678"},{"key":"bibr6-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0025403"},{"key":"bibr7-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.95B1.29835"},{"key":"bibr8-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-007-0324-y"},{"key":"bibr9-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22186"},{"key":"bibr10-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2011-000332"},{"key":"bibr11-0046958019837438","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2011-000752"},{"key":"bibr12-0046958019837438","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.L.01736"},{"key":"bibr13-0046958019837438","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.L.01488"},{"key":"bibr14-0046958019837438","unstructured":"Chatterjee A, King J, Kubendran S, DeVol R.
