One hundred thirty-two female basketball players were observed for lower-extremity overuse injury between 1993 and 2004. Athletes studied between 1993 and 1996 did not receive foot orthotic devices and composed the control group. The treatment group comprised athletes studied between 1996 and 2004. Athletes in the treatment group were given a foot orthotic device before participation in basketball. Data analysis included lower-extremity overuse injury rates and the effect of foot orthotic devices on lower-extremity overuse injury rates by means of an incidence density ratio. The control group had a lower-extremity overuse injury rate of 5.37 per 1,000 exposures, and the treatment group had a rate of 6.44 per 1,000 exposures. The incidence density ratio was not significant (P = .44). This study rejects the concept that foot orthotic devices may assist in prevention of lower-extremity overuse injury in female basketball players. (J Am Podiatr Med Assoc 96(5): 408–412, 2006)
Background: Anterior cruciate ligament injuries are more prevalent in female athletes than in male athletes. Basketball is a high-risk sport for anterior cruciate ligament injury in female athletes. This study was conducted to observe the effect of a foot orthosis on the knee ligament injury rate in female basketball players at one US university.
Methods: One hundred fifty-five players on the women’s basketball team were observed for knee ligament injury from 1992 to 2005. Athletes in the 1992–1993 to 1995–1996 school years (July–June) did not receive a foot orthosis and served as the control group; the treatment group comprised the athletes during the 1996–1997 to 2004–2005 school years (July–June). Athletes in the treatment group received a foot orthosis before participating in basketball. Data analysis included knee ligament injury rates and a comparison of injury rates with an incidence density ratio.
Results: Athletes in the control group had three collateral ligament injuries and three anterior cruciate ligament injuries, for an injury rate of 0.50 for both the anterior cruciate ligament and collateral ligaments. Athletes in the treatment group had four collateral ligament injuries and one anterior cruciate ligament injury, for an injury rate of 0.29 for the collateral ligaments and 0.07 for the anterior cruciate ligament. Athletes in the control group were 1.72 times more likely to sustain a collateral ligament injury and 7.14 times more likely to sustain an anterior cruciate ligament injury than the treatment group.
Conclusions: Foot orthoses may contribute to a decreased knee ligament injury rate in female collegiate basketball players. (J Am Podiatr Med Assoc 98(3): 207–211, 2008)
Background: It has been shown that anterior cruciate ligament (ACL) injuries are more prevalent in female athletes than in male athletes. Soccer and basketball are considered high-risk sports for ACL injury in female athletes. Several studies have reported a relationship between ACL injury and measures of foot structure. This study was conducted to investigate the relationship between foot structure and ACL injury rates in female and male soccer and basketball players.
Methods: One hundred five soccer and basketball players (53 women and 52 men) were recruited and divided into an ACL-normal group (n = 89) and an ACL-injured group (n = 16). Two measures of foot structure (subtalar joint neutral position and navicular drop test values) were recorded for each subject. An independent t test and a paired t test were used to analyze differences in ACL status, foot structure, and sex. A χ2 analysis determined whether the prevalence of ACL injury was independent of sport.
Results: No statistically significant differences were found in the foot structure measures between women and men. Female soccer and basketball players had an ACL injury rate seven times that of male players.
Conclusions: Values derived from subtalar joint neutral position measurement and the navicular drop test were not associated with ACL injury in collegiate female and male soccer and basketball players. (J Am Podiatr Med Assoc 97(5): 371–376, 2007)
