Modified anterior portal for hip arthroscopy

Area of Science:

• Orthopedic surgery
• Arthroscopy
• Hip biomechanics

Background:

• Routine hip arthroscopy portal placement prioritizes minimizing iatrogenic injury and maximizing access.
• Labral repair anchor placement necessitates a distal entry for adequate divergence, risking articular surface perforation.
• Standard portal repositioning for anchor placement can compromise intra-articular access and adequate divergence.

Purpose of the Study:

• To evaluate the utility of a percutaneous anchor delivery system in hip arthroscopy.
• To determine if percutaneous anchors can achieve adequate divergence for labral repair without compromising standard portal function.
• To assess the potential for percutaneous anchors to prevent nonanatomic labral repair due to suboptimal portal placement.

Main Methods:

• Comparative analysis of standard versus percutaneous anchor placement techniques in hip arthroscopy simulations.
• Assessment of portal trajectory divergence and proximity to the acetabular articular surface.
• Evaluation of labral repair outcomes based on anchor position relative to the acetabular rim.

Main Results:

• Percutaneous anchor delivery systems provide sufficient divergence for labral repair.
• This method avoids compromising the utility of standard portals for central compartment access.
• It mitigates the risk of articular surface perforation and nonanatomic labral repair.

Conclusions:

• Percutaneous anchor systems offer a significant advantage in hip arthroscopy for labral repair.
• They enable secure fixation with reduced risk of iatrogenic injury and improved repair anatomy.
• This technique enhances the safety and efficacy of hip arthroscopic labral reconstruction.
