Modified anterior portal for hip arthroscopy.

Abstract

Routine portal placement for the central compartment should be based on minimizing iatrogenic injury and maximizing access. Anchor placement for labral repair/refixation requires a more distal entry position to accomplish sufficient divergence to avoid perforating the articular surface of the acetabulum. If a standard portal for joint access is moved more distal, this can compromise its utility for addressing intra-articular pathology. In addition, it can be difficult to position this portal sufficiently distally to ensure adequate divergence. Moving the anchor away from the rim to avoid perforation, due to suboptimal portal placement, can result in nonanatomic labral repair. Thus a percutaneous anchor delivery system is advantageous in ensuring adequate divergence without compromising routine portal placement for the central compartment.
