Background
This study compares two techniques for intra-articular volume reduction in patients with capsular laxity of the hip—T-capsulotomy plication and interportal capsular shift.
Methods
A cadaveric study was performed with 12 pair-matched specimens randomly assigned to each technique. Capsular volume was measured before and after surgery using the volcano method.
Key Findings
Both techniques produced significant reductions in capsular volume. The interportal capsular shift resulted in a slightly higher volumetric reduction, but the difference was not statistically significant.
Conclusions
Both T-capsulotomy plication and interportal capsular shift effectively reduce capsular volume. The choice of technique may depend on other biomechanical considerations not explored in this study.
What Does This Mean for Patients
Regardless of technique, capsular plication is effective in reducing capsular volume, which may help address capsular laxity in the hip.
