Anthropometric Measurements of the Human Distal Femur: A Study of the Adult Malay Population

Abstract

The distal femurs of 100 subjects (50 men, 50 women) from the Malay population aged between 19 and 38 years were scanned to measure the anterior-posterior (AP) and medial-lateral (ML) width. The mean AP values were 64.02 ± 3.38 mm and 57.33 ± 3.26 mm for men and women, respectively, and the mean ML values were 74.91 ± 3.52 mm and 64.53 ± 3.07 mm. We compared our data to that published previously for the Chinese and Indian populations. It was found that the Malay population had smaller distal femur than that of the Chinese but was larger than that of the Indian population (P < 0.05). In conclusion, although it is well established that Asians have a smaller distal femur size than that of the Western population, the variations in different Asian ethnicities may need to be considered when designing the appropriate knee implant.

Morphometric Study of Lower End of Dry Femur in Gujarat Region and Its Clinical Implication

“…The measurements are very high in Greek (Caucasian) population in male as well as females. [3] These measurements were almost similar to other populations of Asia [4,14] but higher than population of West Bengal [17] and Indonesia [2] . The medial condylar anteroposterior distance (MCAPD) in males was 57.49±2.34 mm while in females it was 53.91±2.05) which was significantly higher in male than female (p<0.01).…”

“…The medial condylar anteroposterior distance (MCAPD) in males was 57.49±2.34 mm while in females it was 53.91±2.05) which was significantly higher in male than female (p<0.01). The lateral condylar anteroposterior distance (LCAPD) in males was 59.02±2.69 mm while in females it was 54.82±2.34 mm which was significantly higher in male than female (p<0.05).These measurements were lower than Greek (Caucasian) [3], Chinese [4] and Malasian [14] populations but higher than Indonesian population [2]. It is found similar to the population of Andhra Pradesh [16] but slightly higher in male and lower in females than population of West Bengal [17].…”

“…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.…”

“…Recent studies are based on difference between gender and ethnic groups. [3,4,[10][11][12][13] Most of the morphometric studies are done with measurement by radiographs, CT scans or Magnetic resonance imaging techniques [2,4,[10][11][12][13][14][15]. There are few data available in which the study is done over dry femur by direct observations [3,16,17].…”

Three Dimensional Morphometry of Distal Femur to Design Knee Prosthesis for Indonesian Population

“…When they were compared with Chinese population, they had larger femur aspect ratio (FB Cheng). However, a study conducted in Malaysia based on Malay population showed slightly larger distal femoral size than that in this study, even though it was still smaller compared with Western counterpart (Hussain et al, 2013). This study was expected to be useful for further study in developing knee implant designs for Indonesian mongoloid population.…”
