SAN DIEGO — Lace-up braces can reduce the occurrence of acute ankle injuries in high school basketball players regardless of their previous history of an ankle injury, according to a presentation at the 2011 Annual Meeting of the American Orthopaedic Society for Sports Medicine, here.

In the prospective, randomized controlled study, Timothy A. McGuine, PhD, ATC, and his team studied 1,460 male and female basketball players ages 13 years to 18 years from 46 U.S. high schools for the 2009-2010 season. Teams were allocated to the intervention and control group using stratified cluster randomization. Athletes in the intervention group wore a lace-up ankle brace (McDavid; Woodridge, Ill.) for each practice and game throughout the season. Athletic trainers at each school recorded ankle brace use as well as all basketball exposures and injuries. Injury rates were estimated per 1,000 exposures and compared between the intervention and control group using a log-rank test. The team examined the relationship between injury rate and ankle bracing while controlling for covariates such as previous injury history, gender, body mass index (BMI), age and level of competition.

A total of 78 acute ankle injuries, 13 knee injuries and 14 other lower extremity injuries were sustained in the control group compared to 26 acute ankle injuries, 20 knee injuries and 30 other lower extremity injuries in the braced group. The incidence of acute ankle injuries was significantly lower in the braced group compared with the control group and was not affected by gender, BMI, age and level of competition.

“Basketball has one of the higher rates for ankle injuries, and this study illustrates how a simple brace can help keep an athlete on the court,” McGuine said.
