Abstract: There is a paucity of data concerning morphological differences in the resected distal femur and proximal tibia between osteoarthritis (OA) and normal knees. The objective of this study was to determine if morphometric differences existed in the resected distal femur and proximal tibia surface between OA and normal knees in the Chinese population. Ninety-eight OA knees and 96 normal ones taken from the Chinese population were measured by computed tomography for femoral mediolateral (fML), medial anteroposterior (fMAP), lateral anteroposterior (fLAP), medial condylar width (fMCW), lateral condylar width (fLCW) and tibial mediolateral (tML), middle anteroposterior (tAP), medial anteroposterior (tMAP), and lateral anteroposterior (tLAP) dimensions to determine morphological differences between OA and normal knees. The mean tMAP and fMCW dimensions were 50.2±3.3 mm and 28.7±2.3 mm for OA, and 48.8±3.8 mm and 27.1±2.2 mm for normal knees, respectively. There were significant differences between OA and normal knees concerning tMAP and fMCW dimensions (p<0.05). The study revealed morphological differences in tMAP and fMCW between the OA and normal knee groups, which may provide guidelines for designing better knee implants that are more size-matching for OA knees.
