Hailer NP, Garland A, Gordon M, et al. - Researchers undertook a nationwide cohort study examining cancer incidences in individuals exposed to total hip arthroplasty due to osteoarthritis vs in unexposed, sex-, age- and residence matched individuals in order to assess the risk of cancer after total hip arthroplasty due to osteoarthritis. They compared 126,276 patients exposed to a cemented total hip arthroplasty (THA) between 1992 and 2012, with 555,757 unexposed individuals and identified a slightly lower adjusted risk of developing any cancer among exposed individuals than unexposed individuals. In exposed individuals, skin melanoma was the only cancer with a statistically significant risk increase. Findings here suggest that the overall risk of cancer does not increase after THA.
