Influence of knee position and examiner-induced motion on the kinematics of the pivot shift

Journal of Experimental Orthopaedics

Table 2 Correlation of the knee position at the start of the reduction event of the pivot shift test with (A) the ensuing anterior translation of the lateral knee compartment and with (B) the flexion angle at the start of the reduction event in the high grade laxity specimen and low grade laxity specimen
