abstract

This study investigated the effect of ketorolac on anteroposterior laxity after anterior cruciate ligament (ACL) reconstruction. A total of 168 ACL reconstructions performed between July 2003 and November 2004 were reviewed. The 6-week KT-1000 manual maximum differences between the ACL-reconstructed knee and nonoperative knee were compared for patients who received ketorolac and those who did not. Mean manual maximum difference in anterior displacement was 0.6 mm in the ketorolac group and −0.6 mm in the non-ketorolac group (P=.03). When bone-patellar tendon grafts were analyzed as a separate group, mean manual maximum difference was 0.5 mm in the ketorolac group and −1.4 mm in the non-ketorolac group (P=.007). When hamstring grafts were analyzed separately, mean manual maximum difference was 0.7 mm in the ketorolac group and 0.4 mm in the non-ketorolac group (P=.59). The use of ketorolac during bone-patellar tendon autograft ACL reconstruction was associated with increased AP laxity at 6 weeks postoperatively. Level of Evidence: Level III, retrospective comparative study.
