Automated patellar height assessment on high-resolution radiographs with a novel deep learning-based approach

Table 2 The results of patellar height indexes calculated by two orthopedic surgeons and those achieved by artificial intelligence (based on a deep learning algorithm and neural network)

	CD index	BP index
Orthopedic surgeon (R#1)	0.93 ± 0.19	0.80 ± 0.17
Orthopedic surgeon (R#2)	0.89 ± 0.19	0.78 ± 0.17
Artificial intelligence	0.92 ± 0.21	0.75 ± 0.19

R#1: Senior specialist; R#2: Younger specialist; CD: Caton-deschamps; BP: Blackburne-Peel. Results of indexes are presented as means ± SD.
