“…6,9,13,15,19 In laboratory tests, divergence between the screw and bone plug of 20° has been necessary to diminished fixation strength. 6,9,13,19 For transtibial drilling, multiple strategies have evolved to limit screw-graft divergence, including hyperflexion of the knee during screw insertion. 2,7,11,16,18,20 There has been less research on limiting divergence with anatomic femoral tunnels.…”
