Abstract

Objective　To measure the angles and length of the curve on posterolateral tibial plateau, and to provide theoretical basis for the clinical plate shaping and the design of new horizontal plate.　Methods　CT data of fifty adult knees were collected (male 31, female 19, mean age 37.68±12.76). Then five points were marked A, B, C, D and E on the edge of posterolateral tibial plateau on the axial CT image when the fibular tip first appeared. The length and angles between each point were measured to provide clinical information on plate length and bending angles.　Results　The average length of the posterolateral tibial plateau curve was（44.04±11.33）mm (19.50~75.50 mm), and the average turning angles were (163.36±7.67) °,(127.95±20.85) ° and (160.50±11.99) °, from anterior to posterior. Clinically five cases were applied with this anatomic measurement, and the postoperative CT showed that the plate and plateau matched completely and contacted closely. 　Conclusion　Obtaining the marginal curve parameter can facilitate intra-operative bending of horizontal belt plate and design of new types of the anatomical plate to increase compatibility with the shape of the posterolateral tibial plateau.
