Background
Femoral head microfracture is a marrow stimulation technique used to treat focal cartilage damage in the hip.
Methods: This study compared 15 patients who underwent microfracture with a matched control group who did not require the procedure. All had Outerbridge grade IV damage and a minimum 2-year follow-up.
Key Findings
Both groups showed significant improvements in PROs. While outcomes were slightly better in the microfracture group, the differences were not statistically significant. Arthroplasty conversion rates were similar.
Conclusions
When performed correctly, femoral head microfracture provides comparable outcomes to patients without such cartilage lesions.
What Does This Mean for Patients
For select patients with focal cartilage damage, microfracture may be a viable and effective arthroscopic treatment option without added risk of early hip replacement.
