Fig. 1From: Reliability of a Robotic Knee Testing Tool to Assess Rotational Stability of the Knee Joint in Healthy Female and Male VolunteersFeatures of the load deformation curve are depicted in the graph—maximum external rotation, maximum internal rotation, rotation at 0 and the calculated features internal rotation laxity, slack and external rotation laxity. The turning points are depicted which divide the curve into the three areas of external rotation, play and internal rotationBack to article page
