Iatrogenic Hip Instability Treated With Periacetabular Osteotomy.

Hip dislocation following hip arthroscopy is a devastating complication. Previous reports of arthroscopy-related iatrogenic instability have focused on strategies aimed at restoring the stabilizing effects of the hip joint capsuloligamentous complex. Less has been written about treatment options for patients in whom deficient acetabular coverage of the femoral head is implicated in the functionally unstable hip joint. Given this relative paucity of information, an optimal treatment approach has yet to be elucidated for these patients. Periacetabular osteotomy has been described as a treatment for iatrogenic hip instability related to surgical hip dislocation; however, to our knowledge, this is the first case of a patient with hip arthroscopy-related iatrogenic instability manifesting as recurrent, frank dislocations treated with periacetabular osteotomy.
