Background
Microfracture of the femoral head is a marrow stimulation technique to treat focal Outerbridge grade IV cartilage lesions.
Methods
Comparison of 15 patients undergoing femoral head microfracture with matched controls who did not require the procedure. Minimum 2-year follow-up assessed PROs and conversion rates to arthroplasty.
Key Findings
- Both groups showed significant PRO improvements.
- Microfracture group outcomes were slightly better but not statistically significant.
- Conversion to arthroplasty was similar between groups.
Conclusions
Femoral head microfracture is a safe and effective adjunct for focal cartilage defects, yielding outcomes comparable to patients without such lesions.
What Does This Mean for Providers?
Microfracture can be considered a viable treatment for focal femoral head cartilage damage without increasing early arthroplasty risk. Patient selection and surgical technique remain critical for success.
