We measured the resected bony surface of the proximal tibia from reconstructed 3D models of the 179 arthritis knees using CT data. We found that the mediolateral (ML) dimension (69.6 ± 9.2 mm) and anteroposterior (AP) dimension (46.1 ± 6.1 mm) were less than those of Westerners. It was observed the medial anteroposterior (MAP) dimension (47.1 ± 7.2 mm) was much larger and closer to middle point of ML dimension than lateral anteroposterior (LAP) dimension (42.9 ± 6.3 mm). The aspect ratio (AR) (1.5 ± 0.07) was constant in Shanghai population. Only half of the prostheses we used in clinic mostly matched the resected bony surface of Shanghai population very well in ML, AP and AR dimension.
