Currently, clear clinical guidelines regarding the timing of elective orthopedic surgeries relative to the menstrual cycle are lacking, often leading to unnecessary surgical rescheduling. Therefore, this study aimed to provide evidence\u2010based guidance for perioperative management and optimal surgical scheduling, thereby addressing a critical clinical need.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study included reproductive\u2010age female patients who underwent hip arthroscopy at the First Medical Center of Chinese PLA General Hospital, the Fourth Medical Center of Chinese PLA General Hospital, and the Department of Sports Medicine at the Second Hospital of Shandong University from December 2018 to September 2023. Patients were categorized into the menstruation group (MP) and the non\u2010menstruation group (NMP) based on whether they were menstruating on the day of surgery. The NMP group consisted of equally sized ovulatory (OP) and luteal (LP) phases. Perioperative outcomes included: intraoperative blood loss, anesthetic dosage, operative time, hemoglobin (Hb) change (within 24\u2009h postoperatively), prothrombin time (PT), and activated partial thromboplastin time (APTT). Postoperative outcomes included analgesic consumption, duration of analgesic use, time to first unassisted weight\u2010bearing ambulation, complications, and urinary tract infections. Functional outcomes were assessed at 24\u2010month follow\u2010up using the Visual Analog Scale (VAS), Modified Harris Hip Score (mHHS), International Hip Outcome Tool\u201012 (iHOT\u201012), Hip Outcome Score\u2010Activities of Daily Living (HOS\u2010ADL), and Hip Outcome Score\u2010Sports Specific Subscale (HOS\u2010SSS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 884 eligible patients, 28 were included in the MP group and 56 matched patients in the NMP group.
