British journal of sports medicine

Abstract

Despite recent advances in rehabilitation and secondary prevention strategies after anterior cruciate ligament reconstruction (ACLR), re-injury rates remain high and long-term outcomes are often disappointing. Deficits in postural stability are shown to be important. To evaluate postural stability during the transition from double-leg stance to single-leg stance in ACLR and non-injured control subjects. Cross-sectional (retrospective). Controlled laboratory study. 20 ACLR subjects (15 females, 5 males), 23.1±13.9 months after ACLR and fully returned to their pre-injury sport, and 20 non-injured control subjects (15 females, 5 males) participated in the study. Both groups were matched for age, gender, weight, height and activity level. All ACL injuries were caused by a non-contact injury mechanism. A transition task from double-leg stance to single-leg stance with eyes closed was performed while standing on a single force plate. Movement speed was standardized. Both legs of each subj...
