摘要

We want to thank Larson et al. for their very astute comments, with which we agree on nearly every point. We are pleased that this research has stirred productive academic dialogue. This is indeed an interesting topic that has evolved significantly in the past few years, and we hope that our responses may contribute to a continued conversation and lead to further study. The first point addresses the study design, which was a matched-pair cohort comparison. We certainly debated between this design and the design Larson et al. suggest, which would compare all surgical hip dislocation (SHD) patients to all patients in the much larger arthroscopy group. Ultimately, our statisticians carried the day, and we heeded their recommendation that a matched-pair comparison is a more statistically powerful design. However, having heard the readers' perspective that it would be more valid to include a large proportion of both groups, we will proceed in performing a follow-up study using the design suggested and will submit that study to Arthroscopy as well.
