To provide an updated synthesis without duplicating prior work, this review was limited to studies published from 2016 onward, following a previous systematic review that comprehensively evaluated outcomes of hip arthroscopy in patients aged 40\u2009years and older through 2015. Inclusion criteria were studies involving patients aged \u2265\u200940\u2009years who underwent hip arthroscopy, published in English, and reporting at least 1 patient\u2010reported outcome measure or clinical outcome. Exclusion criteria included studies that were not Level I, II, or III studies with nonsurgical treatments or studies with duplicate patient cohorts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Six studies were included (2 Level II cohort studies, 4 Level III cohort studies), encompassing 33,091 patients (30,549\u2009\u2265\u200940\u2009years; 92.3%). Among 5 studies (n\u2009=\u20092479), the overall THA conversion rate in patients \u2265\u200940 ranged from 5% to over 21%. The 2\u2010year THA conversion rate ranged from 9% to 13% in patients aged 40 to 60\u2009years, and the 5\u2010year conversion rate was as high as 20.2%. Five studies reporting patient\u2010reported outcome measures showed significant improvements that exceeded the minimal clinically important difference at a follow\u2010up period of 2\u2009years. Functional outcomes (Modified Harris Hip Score, Hip Outcome Score Activity of Daily Living Scale, Hip Outcome Score Sport Scale, and Nonarthritic Hip Score) were significantly worse in patients &gt;\u200945\u2009years compared with those\u2009&lt;\u200945\u2009years. Twenty\u2010one procedure\u2010related complications occurred among 1807 hips (1.16%) in patients 40 and older, the 2 most common being superficial soft\u2010tissue injuries (n\u2009=\u20094) and
