Background
Capsular laxity of the hip can be treated by reducing intra-articular volume via arthroscopic techniques; this study compares two surgical approaches.
Methods
Cadaveric matched-pair study comparing T-capsulotomy plication vs. interportal capsular shift, measuring capsular volume reduction.
Key Findings
- Both techniques significantly reduced capsular volume.
- Interportal capsular shift achieved slightly greater volume reduction, but difference was not statistically significant.
Conclusions
Both techniques are effective for reducing capsular volume; surgical choice may depend on other biomechanical or clinical considerations.
What Does This Mean for Providers?
- Either technique can be confidently employed for capsular volume reduction in cases of hip capsular laxity.
- Decision-making should consider surgeon experience, patient-specific factors, and potential biomechanical impacts not covered by volume reduction alone.
