Combined Hip Arthroscopy and Periacetabular Osteotomy (PAO): Technical Focus on Arthroscopically Elevating the Iliocapsularis and Performing the Open PAO.

In this Technical Note, we discuss the combined hip arthroscopy and periacetabular osteotomy (PAO) for the treatment of symptomatic hip dysplasia, with a focus on the technique we use for the PAO. We identify modifications that can be made during the arthroscopic portion of the procedure to assist in the PAO dissection, including arthroscopic capsular closure and arthroscopic elevation of the iliocapsularis muscle off the capsule, which allows for expedited open exposure during the PAO.
