Fig. 1From: Number of intra-operative cyclic knee motion required to achieve stable graft tension in anterior cruciate ligament reconstruction; a prospective clinical studyMeasurement of graft tension change caused by cyclic knee motion during ACL reconstruction (a) the graft is fixed at an initial tension of 40 N using a tensiometer (Arthlex Inc., Naples, Florida) (b), (c) repeated knee flexion and extension between 0 degree and 90–110 degrees for 10 cycles (d) the graft tension is measured using the tensiometerBack to article page
