The current literature on THA in the pediatric population reveals gaps in research, particularly in patients aged 21 years and younger. Data-driven decision-making is increasingly in demand as THA usage rises. Single-institution studies offer insights for future larger studies, but long-term follow-up data are critical for definitive conclusions, especially concerning implant longevity. Some studies suggest that waiting for triradiate cartilage closure may not be necessary, but further data are needed for a confident determination. Indications for surgery may not significantly impact implant survivorship, except for developmental dysplasia of the hip and tumors, which show an increased risk of revision and higher mortality rates
