Developmental dysplasia of the hip (DDH) is a condition in which the hip joint is improperly formed, leading to pain, instability, and early arthritis. Surgical interventions such as periacetabular osteotomy (PAO) and total hip arthroscopy (THA) are employed to address symptomatic DDH, aiming to improve hip function and mitigate long-term complications. However, the optimal surgical approach for treating DDH remains a subject of debate, particularly regarding the comparative efficacy and outcomes between isolated PAO and concomitant THA.
