Fig. 5From: Increased ACL direct insertion coverage provided more positive biomechanical effects on graft and bone tunnel during knee flexion: a simulation studyA The maximal principal stress on the graft was calculated for each model during flexion simulation; B The equivalent strain on the cancellous bone around the tunnel entrances; C The volume of equivalent strain within 1000–3000 microstrain on the cancellous bone was recordedBack to article page
