CHICAGO — Results showed patients who underwent hip arthroscopy with acetabular microfracture for the management of focal and full-thickness cartilage lesions demonstrated significant improvement in outcomes and survivorship at 10 years.
“We know acetabular microfracture is an option to treat focal and full-thickness cartilage lesions. We have short-[term] and midterm outcomes, [which] demonstrated favorable results; however, we still need long-term data,” David R. Maldonado, MD, said in his presentation at the American Academy of Orthopaedic Surgeons Annual Meeting.
Maldonado and colleagues analyzed 25 hips among patients (mean age of 43.3 years) who underwent primary hip arthroscopy in the setting of femoroacetabular impingement syndrome with acetabular microfracture between May of 2009 and January of 2011. Patient-reported outcomes (PROs) included the modified Harris Hip Score (mHHS), nonarthritic hip score (NAHS), the hip outcome score–sport-specific subscale (HOS-SSS) and VAS pain scores.
Overall, survivorship was obtained in 65.2% of the cohort, and all patients demonstrated “significant improvement” between preoperative and postoperative PROs, Jimenez said. According to the study abstract, mHHS improved by 18.9 points; NAHS improved by 20 points; HOS-SSS improved by 29.4 points; and VAS pain scores decreased from 5 to 1.8 at latest follow-up.
“Based on this result, acetabular microfractures seems to be a feasible alternative; however, there is still room for improvement,” Maldonado concluded.
