Microfracture in the Hip: Results of a Matched-Cohort Controlled Study With 2-Year Follow-up.
Abstract: Microfracture in hip preservation surgery has demonstrated favorable outcomes, but studies with a higher level of evidence assessing microfracture are warranted.
METHODS: Between February 2008 and May 2012, prospectively gathered data for patients undergoing microfracture during hip arthroscopy with a 2-year follow-up were reviewed. All patients were assessed pre- and postoperatively at 3 months, 1 year, and 2 years with 4 patient-reported outcome (PRO) instruments. A matched cohort of patients who did not have full-thickness chondral damage and hence did not receive microfracture was selected on a 1:2 ratio. Matching criteria were sex, age within 6 years, workers' compensation status, concomitant labral treatment, and radiographic parameters. Statistical analyses were performed to compare the change in PROs in both groups.
