title: Anthropometric measurements to design total knee prostheses for the Indian population.
abstract: An anthropometric computed tomography scan study was undertaken to design femoral components in 86 knees (47 osteoarthritic Indians-21 men, 26 women) who matched standards suggested by the Indian Council of Medical Research, 1990. Patients were classified into 3 random groups based on anteroposterior diameter (<55 mm, 55-59 mm, >59 mm). Most Indian men (86.8%) could have the femoral component satisfactorily replaced by available designs. A statistically significant number of women (60.4%, P < .001) had femoral anteroposterior diameters smaller than the smallest available (55 mm) femoral component. Splaying in mediolateral dimension (> 10 mm) in a given anteroposterior size was noted in all 3 groups. This pilot study representative of the Indian population can be used to manufacture prosthetic inventories suitable for most of the Asian-Pacific population having smaller anthropometric measurements than Western populations.
