Microfracture in the Hip: Results of a Matched-Cohort Controlled Study With 2-Year Follow-up
Authors: Domb BG, Gupta A, Dunne KF, Gui C, Chandrasekaran S, Lodhia P
Purpose
To compare outcomes after hip arthroscopy with microfracture for full-thickness cartilage damage versus no microfracture.
Methods
- 79 hips treated with microfracture matched 1:2 with 158 control hips without full-thickness cartilage defects.
- Patient-reported outcomes and pain assessed pre-op and at 2 years.
Key Findings
- Both groups had significant improvements postoperatively.
- Microfracture group had slightly higher pain and lower satisfaction at 2 years but no difference in final functional scores.
- Microfracture remains beneficial for patients with full-thickness cartilage defects.
What Does This Mean for Providers?
- Microfracture can be expected to yield meaningful functional improvement in patients with full-thickness chondral defects.
- Anticipate somewhat higher postoperative pain levels and lower satisfaction compared to patients without such defects.
- Inform patients realistically about expected outcomes and manage expectations accordingly.
- Continue to monitor long-term effects and consider adjunctive therapies to optimize cartilage repair.
