Abstract:

BACKGROUND: Observation and measurement of the size and design of the morphology of artificial knee joint are benefit to promote the stability and histocompatibility after knee prosthesis implantation.
OBJECTIVE: To explore the effect of morphological measurement in total knee arthroplsty.
METHODS: A computer-based search was performed with the key words of “artificial knee joint, prosthesis, measure, design, replacement” in English and Chinese for the literatures that related to the design and measurement of artificial knee joint prosthesis, as well as the literatures that related to the histocompatibility after knee joint prosthesis implantation published from January 1998 to December 2011.
RESULTS AND CONCLUSION: The morphological measurement of the knee joint, namely the three-dimensional finite element model, the relevant parameters and prospects and the biomechanics research, was correlated with selection and design of knee prosthesis. The morphological measurement of the knee joint contained two-dimensional and three-dimensional measurement, and the three-dimensional measurement method was more accurate. There were good correlation between linear dimensions, height and linear dimension, and the application of measurement data has great significance in clinic. The typical knee joint three-dimensional anatomical model can provide a reliable method for the measurement of knee parameters in order to improve the success of the operation.
