Background
Microfracture is a foundational technique for treating focal cartilage lesions during hip arthroscopy. However, the procedure is technically challenging in the hip due to joint depth, curvature, and constrained access.
Methods
This technical note describes an improved microfracture method using a curved drill guide and flexible drill to enhance access and precision in treating chondral defects within the hip.
Key Findings
- The technique is simpler and more ergonomic, improving access to various regions of the acetabulum and femoral head.
- Reduces iatrogenic damage risk and increases procedural efficiency.
- Offers greater reproducibility, especially for surgeons early in their learning curve.
Conclusions
This updated microfracture approach offers a safe, efficient, and effective solution for treating hip cartilage lesions. The simplified technique increases procedural success while maintaining the core biological goals of cartilage stimulation.
What Does This Mean for Providers?
- Consider incorporating flexible drills and curved guides for improved access during hip microfracture procedures.
- The method supports consistent lesion treatment with lower technical demand and risk.
- Ideal for surgeons seeking to optimize cartilage repair strategies in hip arthroscopy without additional complexity or instrumentation.
