ACLR: anterior cruciate ligament reconstruction; SB ACLR: group after single-bundle ACLR; DB ACLR: group after double-bundle ACLR; control: control group; x: arithmetic mean; SD: standard deviation; KHS: the first contact between the foot and the ground; K1: maximal knee flexion at the beginning of stance phase; K2: the biggest extension of the knee during a single stance; KTO: detaching the toes at the end of stance phase; K3: maximal knee flexion during swing phase; K4: maximal extension of the knee joint in the preparatory phase before stance phase; P: significance level (one-way Anova); P ^∗: significance level (parametric t-test for dependent samples).

Presented values obtained in the SB and DB ACLR groups refer to involved leg while values obtained in the control group refer to the right leg.
