p was compared between ratios from different races. The significant difference had been found except for the ratio from the study of Xiao et al
FW femoral width, AT adductor tubercle, ME medial epicondyle, LE lateral epicondyle, TT tibial tubercle, FH fibular head, IPP the inferior pole of the patella, DJL distance from landmarks to the distal joint line, PJL distance from landmarks to posterior joint line
