Inclusion criteria were an age range of 16 to 55 years and a minimum follow\u2010up of 2 years. MRI was used to evaluate the preoperative and postoperative conditions of the labrum and the presence of paralabral cysts. Furthermore, the correlations between the presence of paralabral cysts and demographic and radiographic variables were investigated. Additionally, patient\u2010reported outcomes (PROs), minimal clinically important difference, and complications were reported during the final follow\u2010up evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 23 patients were included in the final analysis, with an average follow\u2010up of 26.6 \u00b1 3.4 months (range, 24\u201032 months). All patients diagnosed with symptomatic DDH exhibited labrum tears. MRI scans revealed paralabral cysts in 10 of 24 (41.6%) patients, with a significant correlation noted between the presence of cysts and preoperative lateral center\u2010edge angle (\u03c1 = \u22120.649;\n                      <jats:italic>P<\/jats:italic>\n                      = .001), anterior center\u2010edge angle (\u03c1 = \u22120.637;\n                      <jats:italic>P<\/jats:italic>\n                      = .001), T\u00f6nnis angle (\u03c1 = 0.593;\n                      <jats:italic>P<\/jats:italic>\n                      = .002) and age (\u03c1 = \u22120.444;\n                      <jats:italic>P<\/jats:italic>\n                      = .034). Postoperative MRI scans at 1 year showed resolution of all paralabral cysts, while labral tears were found to persist. At the end of the follow\u2010up period, most patients improved considerably in PROs compared with preoperative values.
