A matched-pair controlled study of microfracture of the hip with average 2-year follow-up: do full-thickness chondral defects portend an inferior prognosis in hip arthroscopy?

Abstract: This study compared 2-year clinical outcomes in hip arthroscopy patients treated with microfracture to a matched control group without full-thickness chondral damage.

METHODS: During the study period between June 2008 and July 2011, data were collected on all patients treated with hip arthroscopy who underwent microfracture. All patients were assessed pre- and postoperatively with 4 patient-reported outcome (PRO) measures. Pain was estimated on the visual analog scale (VAS), and satisfaction was measured on a scale from 0 to 10. A matched-pair group of patients who did not undergo microfracture was selected in a 1:2 ratio. Matching criteria were age within 5 years, sex, surgical procedures, and radiographic findings.
