Purpose
To detail a minimally invasive technique using arthroscopically assisted transthorchanteric drilling (microfracture) for treating difficult-to-access femoral head cartilage defects.
Methods
Use of a 2.7-mm K-wire drilled transtochanterically under arthroscopic and imaging guidance to stimulate cartilage repair in medial and parafoveal defects.
Key Findings
- The technique stimulates fibrocartilage formation with less morbidity than open procedures.
- Facilitates treatment of lesions otherwise challenging to access arthroscopically.
- Associated with faster recovery and fewer complications.
What Does This Mean for Providers?
- This technique expands microfracture indications to femoral head defects inaccessible by standard arthroscopy.
- It allows a less invasive approach with good safety profile; appropriate imaging guidance is critical.
- Should be considered when managing focal chondral defects in the femoral head to optimize cartilage repair.
