Exclusion criteria comprised nonlabral tear indications, prior hip surgery, incomplete data, or loss to follow-up. Patients with paralabral cysts confirmed by magnetic resonance imaging (MRI) were designated as the cyst group (n = 35), whereas a control group without cysts (n = 35) was selected using 1:1 propensity score matching (PSM) based on sex, age, and body mass index (BMI). Demographic data, radiographic parameters (alpha angle, lateral center edge angle), and PROs, including visual analog scale (VAS), modified Harris Hip Score (mHHS), minimal clinically important difference (MCID), and Patient Acceptable Symptom State (PASS), were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Among 841 eligible cases, paralabral cysts were present in 41 (4.9%) on MRI scan. After 6 cases were excluding because of incomplete data or bilateral surgery, 35 patients (hips) were included in the cyst group. Using 1:1 PSM for age, sex, and BMI, the authors selected an equivalent control group (noncyst group; n = 35), yielding a final cohort of 70 patients (70 hips). No significant differences were found in age (39.2 \u00b1 11.34 vs 39.9 \u00b1 11.92 years;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .790), sex (70% vs 62.9% female;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .806), BMI (23.87 \u00b1 3.1 vs 23.60 \u00b1 3.14 kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      ;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .711), or symptom duration (22.51 \u00b1 30.37 vs 25.6 \u00b1 25.81 months;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .635) between the noncyst and cyst groups.

One patient in each group required revision surgery or total hip arthroplasty during follow-up. Overall, 80.0% (56\/70) of patients achieved the MCID, and 82.9% (58\/70) attained the PASS.
