Modifications can be made in progressive resistance exercise for strengthening knee internal rotators. In this current study, 20 subjects with anterior drawer laxity were randomly assigned to three groups adopting different training modes: plate-loaded squat press (SP), plate-loaded kneeling leg curl with internal rotation (KLCIR), and plate-loaded kneeling leg curl (KLC). Static stability, dynamic stability, and isokinetic strength were measured. The purpose of this paper was to find out an optimal solution to the enhancement of the static and dynamic knee stability to a great extent.
