Detail of Fig. 2 with maximum/minimum principal strain along path at lateral (left) and medial (right) femoral surface at 45% (top) and 37% (bottom) of the gait cycle for different stem designs (Corail, SP-CL, Spotorno) and intact bone. Cranial-caudal path summarized with 6th degree polynomic functions, single measurement points shown as transparent circles demonstrating large variance with position.
