“…For example, morphologic features of the femoral notch and the tibial slope have been identified as risk factors for anterior cruciate ligament rupture in the knee. 2,3,19,33 In the shoulder, previous research has shown that GHJ morphology can vary significantly between individuals. For example, an anatomic study by McPherson et al 20 suggested that 95% of 93 cadaveric shoulder specimens analyzed had a glenoid radius of curvature (ROC) ranging from 17 mm to 47 mm.…”

“…The second phase focused on a multivariate evaluation of knee-joint geometry and its effect on the risk of ACL injury. [16][17][18][19][20][21] Detailed results from the first phase are currently under review for publication and, consequently, we can provide only an overview of the study design, but we encourage the reader to consider the detailed findings once they have been published. The findings from the multivariate work in the second phase have been published.…”

“…The findings from the multivariate work in the second phase have been published. [16][17][18][19][20][21] Athletes from 36 institutions (8 colleges, 28 high schools) were monitored prospectively over 4 years for the occurrence of ACL injuries. A total of 109 case participants (70 females, 39 males) who sustained a first-time grade III noncontact ACL injury during involvement in a schoolorganized sport were enrolled in the study.…”

“…Bilateral 3-T images were obtained on all case and control participants and used to measure 32 aspects of knee anatomy. 11,16,19,21 Multivariate analysis revealed differences between females and males for the specific aspects of knee-joint geometry that had the greatest association with ACL injury risk. When male athletes were considered as a group, decreases in the wedge angle of the posterior lateral meniscal horn and ACL volume had the highest associations with the risk of sustaining a noncontact ACL injury (odds ratio [OR] ¼ 1.23 per 18 decrease in wedge angle and OR ¼ 1.43 per 0.1-cm 3 decrease in ACL volume).…”

A nterior cruciate ligament (ACL) injuries produce significant joint trauma and have been implicated as the inciting event for both short-term and longterm changes within the articular structures of the knee. [1][2][3][4][5][6][7][8] Regardless of whether a patient chooses surgical or nonsurgical treatment, ACL injury is associated with the onset of posttraumatic arthritis. 9 Consequently, recent researchers have focused on understanding the mechanisms and factors that place individuals at increased risk for sustaining this severe injury. However, variations in study designs and methods have led to conflicting reports regarding these relationships. For example, exclusion criteria used for control participants (eg, combining control participants who have a history of knee pain with those who have normal, pain-free knees) and the approaches used to match case and control participants vary widely among studies. In addition, previous authors have obtained data from the affected knees of ACL-injured patients after the injury. This approach does not take into consideration that the ACL injury itself is capable of producing both shortterm and long-term changes in knee-joint geometry. 1,5 Furthermore, few investigators have used measurement techniques with established interobserver and intraobserver measurement reliability.10 Finally, many researchers have evaluated men and women as a combined group. However, in light of the disparities that exist between the sexes in ACL injury rates, knee-joint geometry, anatomical alignment, joint laxity, demographic characteristics, and strength, male and female models of injury risk should be considered separately. 11This keynote presentation provided a summary of findings from our group's previous and ongoing research efforts that have focused on identifying the factors associated with increased risk of ACL injury. For clarity, the findings are organized in 3 sections: ''Epidemiology of ACL Injury,'' ''Evaluation of ACL Injury Screening Tools,'' and ''Development of ACL Injury Risk Models.'' Epidemiology of ACL InjuryOur epidemiology investigation evaluated the independent effects of athlete sex, level of competition, and sport on the risk of sustaining an ACL injury. 11 We prospectively followed athletes from 26 institutions (8 colleges, 18 high schools) over 4 years to determine the incidence of firsttime, noncontact ACL injuries. After controlling for differences in level of play and sport, we found that an athlete's sex had an independent influence on the risk of injury: female athletes' risk of experiencing a noncontact ACL injury was 2.10 times greater than that of their male counterparts.11 When athlete sex and sport were controlled, collegiate athletes were at greater risk for incurring a noncontact ACL injury than were high school athletes (relative risk [RR] ¼ 2.38). 11When controlling for athlete sex and level of play, we observed that the risk of sustaining a noncontact ACL injury was greatest in soccer (RR ¼ 1.77) and rugby (RR ¼ 2.23) compared with all other sports s...

“…35 The authors of a study in this month's AJSM attempt to rein in some of this confusion by investigating many of these parameters simultaneously. 34 Although ACL tears would seem to be common occurrences, they are rare enough that prospectively performing MRI examinations of healthy athletes and then waiting for some of them to tear their ACLs would require a very large and expensive study to achieve adequate statistical power. For this reason, prior studies have generally adopted a case-control model, in which the images from athletes with ACL tears have been compared with those who underwent imaging for other reasons.…”
