Marked Decline in Revision Rate Over Time After Hip Arthroscopy for Femoroacetabular Impingement Syndrome.

Background: There is a body of scientific evidence showing good short-term outcomes after arthroscopic treatment for femoroacetabular impingement syndrome (FAIS); however, less is known about the change in short-term outcomes over time. Purpose: To (1) evaluate short-term outcomes after arthroscopic treatment for FAIS between 2 groups with index surgery at different periods and (2) assess whether there has been a change in clinical markers over time. Study Design: Cohort study; level of evidence, 3. Methods: Data were retrospectively reviewed from a local hip arthroscopy registry, with primary hip arthroscopic treatment for FAIS and age ≥18 years as the inclusion criteria. The exclusion criteria consisted of surgical intervention to either hip before the primary arthroscopic intervention of the studied hip. Patients who underwent treatment between 2012 and 2013 were compared with patients who underwent treatment between 2017 and 2018. The revision rate within 2 years postoperatively was used as the primary outcome. Changes in patient-reported outcome measures (PROMs)-including the International Hip Outcome Tool, the Copenhagen Hip and Groin Outcome Score, European Quality of Life-5 Dimensions Questionnaire, European Quality of Life Visual Analog Scale, the Hip Sports Activity Scale, visual analog scale for overall hip function, and a single question regarding satisfaction with treatment-were used as secondary outcomes. Results: Comparison of revision rates revealed a statistically significant decline from 9.1% for patients treated between 2012 and 2013 (n = 571 patients) to 1.2% for patients treated between 2017 and 2018 (n = 485 patients) ( Conclusion: There was a significant decline in revision rates over time. No changes were observed in PROMs over time.
