Background
This study evaluates mid-term outcomes after acetabular microfracture performed during hip arthroscopy for full-thickness chondral lesions.
Methods
Fifty-three patients underwent acetabular microfracture during hip arthroscopy and were followed for a minimum of 5 years. Patient-reported outcomes (PROs), pain via visual analog scale (VAS), and satisfaction were recorded.
Key Findings
- Significant improvements were seen in all PROs and VAS scores at follow-up.
- 72.1% of hips survived without conversion to total hip arthroplasty (THA).
- Secondary arthroscopy was required in 10.8% of cases.
Conclusions
Acetabular microfracture during hip arthroscopy yields favorable clinical outcomes and good mid-term survivorship, with careful patient selection crucial to minimize progression to THA.
What Does This Mean for Providers?
Providers should consider acetabular microfracture as an effective treatment for full-thickness acetabular cartilage defects in selected patients. Proper patient selection and counseling on prognosis are essential to optimize long-term joint preservation.
