A 29-year-old female patient reports perineal hypoesthesia and dysesthesia on the operative side immediately following hip arthroscopy for treatment of a labral tear and femoroacetabular impingement. Which of the following operative techniques might have decreased the risk of this complication?
    • Labral repair
    • A labral repair would not affect the risk of pudendal nerve palsy.


    • Shorter traction time
    • A shorter traction time can decrease the risk for injury to the pudendal nerve.


    • Perineal post of <8 cm
    • A perineal post of >8 mm may increase risk of palsy by distributing force on a smaller surface area.


    • Extensile capsulotomy
    • Performing an extensile capsulotomy would not affect the risk of pudendal nerve palsy.
