Given the critical role of the hip capsule in maintaining joint stability, the extent and configuration of capsulotomy may have meaningful implications for postoperative outcomes. However, investigations directly comparing clinical outcomes of capsulotomy types in a contemporary study population are lacking.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose:<\/jats:title>\n                    <jats:p>To compare patient-reported outcomes (PROs), achievement of clinically significant outcomes, and reoperation-free survival between interportal and T-capsulotomy in patients undergoing hip arthroscopy at a minimum 2-year follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>Cohort study; Level of evidence, 3.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Patients who underwent hip arthroscopy between October 2020 and November 2022 with \u22652-year follow-up were included.
