Abstract:
Objective To provide the anatomic parameters and X-ray data of adult knee joint for the Northwestern Chinese people through measuring the knee joint of Northwestern aged people; at the same time, to provide reference for total knee arthroplasty (TKA) prosthesis design, selection and skills of surgery. Methods Totally 200 Northwestern Chinese aged people, aged above 40 years old, 100 males and 100 females, were selected randomly. X-ray films of knee were shot in the anterioposterior view and lateral position. Measurement and recording: angle PT, angle FT, patellar thickness, tibial plateau to fibular head distance (DPF). When the values were obtained, they were statistically analyzed based on gender and side. And we compared them with foreign data. Results Angle PT, angle FT, H and DPF did not differ significantly between the two sides (P>0.05). The differences in patellar thickness and DPF between patients of different gender was obvious (P<0.05), but there was no significant difference in angle PT and angle FT between the two genders (P>0.05). The differences in patellar thickness, DPF, angle PT and angle FT between the Chinese people and foreigners were obvious (P<0.05). Conclusion Angle PT, Angle FT, DPF and patellar thickness should be measured routinely before TKA in order to ensure successful operations.
