The linear mixed model was used to estimate the factors affecting Mose hip ratio on most recent follow-up radiographs.
CI, confidence interval; GMFCS, Gross Motor Function Classification System; IMPO, immediately postoperative; MHS, Mose hip scale;MP, migration percentage;NSA, neck shaft angle; Preop, preoperative.
