The patient’s physician, Atul Kamath, MD, who is also director of the center, notes that anteroposterior imaging showed that the patient is skeletally mature. And while the cartilage on his left hip was preserved, Dr. Kamath also noticed a crossover sign, indicating acetabular retroversion.
Given the global acetabular retroversion, the procedure could not be accomplished by a simple rim trimming of the cranial aspect of the socket through an arthroscope. Dr. Kamath explains, “This would cause insufficiency or a lower volume socket that might cause secondary or iatrogenic instability of the hip.”
Dr. Kamath chose to address the complex deformity with introverting, or reverse PAO (anteverting periacetabular osteotomy), where the shape of the socket is manipulated to create more effective anteversion. He notes that the patient is doing well and was able to return to his work with great functional improvements and decreased pain.
“This offers a powerful method for treating the impingement within the hip, and then also affording more normal biomechanics.”
