Deinonychus had to bend its knees round the guts between its legs, whereas
similarish dinos (espec. Troodon) whose pubes pointed forwards could keep
their knees closer together, and have the neck of the femur more at right
angles with the main shaft.  This probably meant more efficient running,
though modern birds had Deino's problem in spades and some are quite good
