However, progression of arthritis or pain can necessitate conversion to total hip arthroplasty (THA). While conversion to a THA is a viable option, it does carry multiple risks. The purpose of this study was to identify whether performing conversion from HA to THA carries an increased risk of post-operative joint complications when compared to elective THA.<\/jats:p> <\/jats:sec> Methods<\/jats:title> An administrative claims database was queried to identify patients who underwent conversion from a HA to a THA. Incidences of prosthetic dislocation, prosthetic joint infection (PJI), periprosthetic fracture, aseptic loosening, and revision were collected and compared to elective primary THA with multivariable logistic regression.<\/jats:p> <\/jats:sec> Results<\/jats:title> Patients undergoing conversion THA had significantly higher risks of all joint complications examined at both 1 and 2 years after surgery. These included prosthetic dislocation (1-year: OR 2.95; 2 years: OR 3.77), PJI (1-year: OR 1.38; 2 years: OR 2.13), periprosthetic fracture (1-year: OR 2.95; 2 years: OR 3.75), aseptic loosening (1-year: OR 6.86; 2 years: OR 7.70), and revision (1-year: OR 3.65; 2 years: OR 6.73).<\/jats:p> <\/jats:sec> Conclusion<\/jats:title> Performing conversion arthroplasty from HA to THA is associated with an increased risk of multiple joint complications in both the short and mid-term follow-up period. Surgeons should consider these complications when indicating HA for femoral neck fractures and elective conversion arthroplasty.<\/jats:p> <\/jats:sec>","DOI":"10.52965\/001c.25539","type":"journal-article","created":{"date-parts":[[2021,7,22]],"date-time":"2021-07-22T20:36:35Z","timestamp":1626986195000},"source":"Crossref","is-referenced-by-count":15,"title":["Complication Rates of Hemiarthroplasty Conversion to Total Hip Arthroplasty Versus Primary Total Hip Arthroplasty"],"prefix":"10.52965","volume":"13","author":[{"given":"Sione A.","family":"Ofa","sequence":"first","affiliation":[{"name":"Tulane University School of Medicine","department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Austin J.","family":"Ross","sequence":"additional","affiliation":[{"name":"Tulane University School of Medicine","department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bailey J.","family":"Ross","sequence":"additional","affiliation":[{"name":"Tulane University School of Medicine","department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliva C.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tulane University School of Medicine; Department of Orthopaedic Surgery, Louisiana State University School of Medicine and Southeast Louisiana Veterans Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William F.","family":"Sherman","sequence":"additional","affiliation":[{"name":"Tulane University School of Medicine","department":["Department of Orthopaedic Surgery"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"30777","published-online":{"date-parts":[[2021,7,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"c2332","DOI":"10.1136\/bmj.c2332","article-title":"Primary total hip arthroplasty versus hemiarthroplasty for displaced intracapsular hip fractures in older patients: systematic review","volume":"340","author":"C.
