Prolonged joint effusion after hip arthroscopy may be associated with persistent symptoms

Research to investigate causes for continued symptoms in patients who undergo hip arthroscopic treatment are an opportunity to improve outcomes. A disconcertingly large number of patients (47-66%) show a joint effusion/synovitis on MRI at 6-12 months after hip arthroscopy for FAIS, and a recent study shows that this is associated with inferior 2-year clinical outcomes compared to patients without effusions.
