Records were queried between 2010 and 2021 with a diagnosis of JHS, including Ehlers\u2010Danlos syndrome (EDS) and Marfan syndrome. Propensity matching was performed with a randomly generated control cohort without a diagnosis of JHS to account for age, sex, Charlson comorbidity index, diabetes, and obesity. Multivariable logistic regression was used to compare rates of patellar dislocation over a 1\u2010 and 2\u2010year period between the 2 cohorts while controlling for previous knee injury or surgery. Patients who sustained a patellar dislocation over the 2\u2010year period were followed to calculate rates of surgical intervention and subsequent revision.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In a population of 91,747, those with JHS experienced patellofemoral instability at a significantly increased rate at both a 1\u2010year (adjusted odds ratio [aOR] 11.40; 95% confidence interval 9.23\u201014.25,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001) and 2\u2010year (aOR 8.73; 7.36\u201010.44,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001) periods.
