Inclusion criteria were adult patients who had undergone primary unilateral hip arthroscopy for femoroacetabular impingement syndrome (FAIS). The study group was defined by the presence of a superolateral acetabular subchondral cyst on preoperative imaging. A control group was matched on age; sex; body mass index (BMI); lateral center-edge angle (LCEA); alpha angle; arthroscopic treatments of femoroplasty, acetabuloplasty, and labral treatment (ie, repair, reconstruction, or debridement); Beck chondral grade; and minimum 2-year outcomes using visual analog scale (VAS) for pain, International Hip Outcome Tool-12 (iHOT-12), minimal clinically important difference (MCID), substantial clinical benefit (SCB), and Patient Acceptable Symptom State (PASS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The study included 82 patients, of whom 41 composed the study group and 41 served as matched control patients.
