This study compared the outcomes of metal-on-metal hip resurfacing (HR) in patients performed for an indication of OA secondary to trauma to compared to PT ON. Metal-on-metal resurfacing arthroplasties were performed on 62 hips, 43 with PT OA and 19 with PT ON with secondary osteoarthritis. There were 51 males and 11 females. All patients were followed up clinically and radiographically with a mean follow-up of 87.2 months. Clinical outcome scores, survivorship, and radiographs were compared between the PT OA and PT ON group. The clinical outcomes for the PT ON and PT OA groups were similar with a survival rate of 95% (95% CI 82.1% to 98.8%) for the PT OA group alone at 8 years and 91% for those with PT OA with ON at 8 years (95% CI 50.8%-98.7%). The Kaplan-Meier survivorship curves for the cohorts of PT OA and PT ON patients were not statistically significantly different (Log rank, p=0.6036). Metal-on-metal hip resurfacing appears to be a safe and effective procedure for the treatment of both post-traumatic osteoarthritis and osteonecrosis.<\/jats:p>","DOI":"10.5301\/hip.2012.9226","type":"journal-article","created":{"date-parts":[[2012,5,1]],"date-time":"2012-05-01T05:58:59Z","timestamp":1335851939000},"page":"195-202","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Results of Conserve Plus\u00ae Metal-On-Metal Hip Resurfacing for Post-Traumatic Arthritis and Osteonecrosis"],"prefix":"10.1177","volume":"22","author":[{"given":"Regina P.","family":"Woon","sequence":"first","affiliation":[{"name":"Children's Hospital Los Angeles, Los Angeles - USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alicia J.","family":"Johnson","sequence":"additional","affiliation":[{"name":"Joint Replacement Institute, Los Angeles - USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harlan C.","family":"Amstutz","sequence":"additional","affiliation":[{"name":"Joint Replacement Institute, Los Angeles - USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,4,24]]},"reference":[{"key":"bibr1-HIP.2012.9226","unstructured":"National Joint Registry for England and Wales, 6th annual report 2009.
