What did I do?
My PhD included studies on patients with femoroacetabular impingement syndrome (FAIS). We performed (1) a systematic review with meta-analysis1 investigating patient-reported outcomes before and after hip arthroscopic surgery in patients with FAIS; and (2) a cohort study in which I investigated patient-reported outcomes, hip muscle strength and physical activity level in 60 patients with FAIS before and after hip arthroscopic surgery.2–5
Why did I do it?
During the past decade, there has been a steep increase in hip arthroscopies performed (eg, a 335% increase from 2007 to 2011 in an American private payer population).6 While several studies had been published on patient-reported outcomes after surgery, none had synthesised studies to get an overview of how patient symptoms developed over time.
