Uniform and reliable assessment of bone union on radiographs in osteotomies around the knee: a novel classification system
The UBU classification provides a reliable and standardized method for evaluating bone union after osteotomies around the knee. It incorporates negative union signs and demonstrates strong inter- and intra-rater agreement, as well as strong correlation with CT imaging. Further research should validate its diagnostic accuracy and clinical utility.
