The effect of functional bracing on subsequent knee injury in anterior cruciate ligament (ACL) deficient professional skiers was evaluated. A cohort of 180 ACL-deficient skiers was identified from a knee screening of 9410 professional skiers from 1991-1997. An ACL-deficient knee was defined by an abnormal examination (Lachman or pivot-shift) and a > or = 5-mm KT-1000 manual maximum difference. The dependent variable was subsequent knee injury, which occurred in 12 knees. A significantly higher proportion of injuries occurred in nonbraced skiers compared with braced skiers (P = .005). The risk ratio for subsequent knee injury comparing nonbraced with braced skiers was 6.4 (13% and 2%, respectively). Univariate analysis revealed no significant effects of the other covariates. Logistic regression identified bracing status (P < .01; odds ratio = 8) and KT-1000 manual maximum difference (P = .02; odds ratio = 1.3) as significant multivariate risk factors for subsequent knee injury, controlling for covariates.
