Postural sway during one-leg standing with eyes closed on the affected leg following anterior cruciate ligament (ACL) reconstruction was quantified and compared to that on the contralateral normal leg, and that on the leg of normal control group. We examined 19 patients (11 males, 8 females) with ACL reconstruction using hamstring-tendons (postoperative period: average of 21 (12-68) months) and 10 healthy normal volunteers (8 males, 2 females). Using the postural sway meter, we measured environmental area and locus length per unit area. There is no statistical difference in environmental area and in locus length per unit area among 3 groups. Postural sway in the knee more than 1 year after ACL reconstruction was equal to those in control group.
