The final outcome score was based on pain utility measures. The probabilities of all cases and the utility score were obtained by literature review.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> The decision model favoured concurrent prophylactic FVO for the contralateral stable hips over observation (pain utility measure scores 0.814 vs 0.781). In a one\u2010way sensitivity analysis, the decision model favoured concurrent prophylactic FVO when the unstable hip rate of contralateral stable hips during observation was 27% or over. Concurrent prophylactic surgery also demonstrated higher utility scores than observation when the unstable hip rate after FVO was between 0% and 29%.<\/jats:p><jats:p><jats:bold>Interpretation\u2002<\/jats:bold> The decision analysis model demonstrated that concurrent prophylactic FVO for a contralateral stable hip in individuals with cerebral palsy undergoing hip reconstructive surgery was beneficial from a medical perspective, which was based on current evidence.<\/jats:p>","DOI":"10.1111\/j.1469-8749.2011.04172.x","type":"journal-article","created":{"date-parts":[[2012,1,23]],"date-time":"2012-01-23T14:43:38Z","timestamp":1327329818000},"page":"231-239","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Prophylactic
