This study was designed as a multicenter randomized trial to answer an important clinical question about a rare condition, and to do so with a clearly defined objective and validated set of outcomes. This simple trial can be executed on a relatively small budget with simple outcome measures, and recruitment of a small number of patients at each of a few centers well equipped for research. By involving multiple surgeons and patients from various geographies, we improve the generalizability of this study. Our institution and collaborating institutions have been successful in completing randomized clinical trials in the past. This study will answer a clinical question that is important and current, providing orthopedic surgeons with an evidence-based answer: the optimal technique in treating painful irreducible hip dislocation in patients with cerebral palsy. The proposed research study aims to fill these gaps.
