Gender differences in the knees of Chinese population

Abstract: The goal of this study was to characterize the geometry of the distal femur and proximal tibia in the Chinese population. Three-dimensional models of twenty female and twenty male knees were constructed using CT images. The morphologic measurements of the distal femur included mediolateral (ML) and anteroposterior dimension of medial and lateral condyles (MAP, LAP), femoral aspect ratio (ML/LAP), medial and lateral condylar width, intercondylar notch width, notch width index (NWI), and trochlear groove orienta… Show more

“…Most of the morphometric studies are done with measurement by radiographs, CT scans or magnetic resonance imaging techniques which are indirect methods [2,4,[10][11][12][13][14][15]. There are studies which suggest that indirect method of measurement are found inaccurate and not precise even though they are corrected by the projection method as well as by the resolutions.…”

“…Because the direct method of measurement is accurate we can match these morphometric data for making of prosthesis for joint replacement surgery with the resected surface of the knee that will improvement factor for long term success of prosthesis and less complications in total knee joint replacement. There are several studies done which are based on western population and also the prosthesis available in market is based on western population [9,11] although the Indians have smaller knees as compared to them. This study will provide data and will influence in the clinical outcome to design improved prosthesis based higher in male than female (p<0.05).…”

“…So measurements of this variable is very important. [5,11,23,24] In a recent CT study on an Iranian population, intercondylar notch width was measured as 20.39±3.4 mm, 21.76 in males and 17.96 mm in females. [11] These results are similar to our findings of NW in bony and MRI specimens.…”

“…[4][5][6][7][8][9][10][11][12][13] Compared with Caucasians, Asians have narrower distal femurs and thus a larger anteroposterior/mediolateral ratio or aspect ratio. [14][15][16][17] The higher aspect ratio leads to more severe mediolateral overhang of the femoral component and thus Asian females are at higher risk of soft tissue impingement and poorer outcome following TKA. [18][19][20] Asian women with conventional LPS knee prosthesis of size E and larger tend to have mediolateral overhang of the femoral component resulting in soft tissue impingement after TKA.…”
