Differential Biomechanical Effects of an ACL Injury Prevention Program in Women's Basketball and...
Anterior Cruciate Ligament InjuryAnterior cruciate ligament injury programs are less successful in women's basketball than soccer players, yet the reason for this discrepancy is unknown. Thus, this study will recruit high school aged girl's basketball and soccer players, randomized teams into control and experimental groups, administer an ACL injury prevention program in the experimental group and compare the two groups on their lower extremity biomechanics before and after completion of the program. Biomechanical analyses will help determine the extent to which women's basketball and soccer players respond differently to a uniform injury prevention program, and whether this prevention program provides an adequate stimulus to improve lower extremity biomechanics during basketball-specific tasks.
Neuromuscular Intervention Targeted to Mechanisms of ACL Load in Female Athletes
ACL InjuryFemales who participate in cutting and landing sports suffer anterior cruciate ligament (ACL) injuries at a 2 to 10-fold greater rate than males participating in the same high-risk sports. Fifty to 100 percent of ACL injured females will suffer osteoarthritis of the injured knee within one to two decades of the injury. External knee abduction moment (LOAD) predicts ACL injury with high sensitivity and specificity in female athletes. Control of lateral trunk motion (LTM) also predicts ACL injury with similar levels of sensitivity and specificity in female athletes. These predictors may be linked, as lateral positioning of the trunk can create high knee abduction load via both biomechanical and neuromuscular mechanisms. The mechanism of ACL injury in females include high knee LOAD and high LTM, with the majority of body weight shifted over the injured limb and the foot positioned lateral to the body's center of mass. An unanticipated perturbation is also often a contributor to the injury mechanism. LTM may result in increased knee LOAD by increasing the lateral position and magnitude of the GRF vector (ΔGRFv) or by increasing reactive hip adductor torque (HAdT). Our long-term objectives are to determine the mechanisms that cause ACL injury in female athletes and to develop neuromuscular training (NMT) interventions that specifically target these mechanisms. If the objectives of this proposal are achieved, an evidence-based NMT intervention will be developed and made available nationally that will effectively and efficiently reduce ACL injury risk in high-risk female athletes. The major goal of this proposal is to determine if increased LTM increases coronal plane knee load in high-risk groups of female athletes.
Prognosis Study of Different Anterior Cruciate Ligament Surgery Methods
Anterior Cruciate Ligament InjuriesFrom June 1, 2016, to July 1, 2017, a total of 406 patients with ACL rupture were randomly assigned to three different ACL surgeries: anatomical single-bundle, central axial single-bundle and double-bundle. A prospective randomized cohort study was conducted.
BFR Therapy After ACL Reconstruction
ACL InjuryQuadriceps Muscle AtrophyThis study is a prospective, double-blinded, randomized control trial examining the effect of blood flow restriction (BFR) therapy on reducing post-operative quadriceps atrophy in patients undergoing anterior cruciate ligament reconstruction (ACLR). Following ACLR, patients will undergo a rehabilitation protocol either w/ BFR therapy or sham BFR therapy.
Decreasing Knee Injury Risk Factors With Neuromuscular Training
ACLAnterior Cruciate Ligament InjuryAnterior cruciate ligament (ACL) tears are disabling injuries that place a significant burden on the athlete. Roughly 80% of these injuries are linked to a noncontact mechanism, with more than 70% of them occurring while landing from a jump. Female athletes are at higher risk of sustaining a noncontact ACL injury due to the higher number of risk factors that they possess compared to their male counterparts. Due to this statistic, ACL prevention programs have been developed over the past 15 years in attempt to reduce this risk among the female athletic population. These programs have been shown to reduce the rate of noncontact ACL injuries in females by correcting the risk factors associated with them. However, it remains unclear as to whether these positive results are solely due to the program or a higher exercise workload in its participants. The purpose of this study is to evaluate the effectiveness that an ACL prevention program has on modifying at-risk landing mechanics (associated with noncontact ACL injury) compared to a resistance training program of equal workload.
Effect of the FIFA 11+ Injury Prevention Program on Performance & Movement Control in Young Female...
Injury of Anterior Cruciate LigamentIn response to high injury rates in soccer, the Fédération Internationale de Football Association (FIFA) developed an injury prevention program called the "11+". It is designed to replace a standard warm-up and takes about 20 minutes to complete. The program has proven remarkably effective in decreasing the rate of injury in soccer players. However, uptake of the 11+ has been less than desired. Adoption of the program may be increased if additional benefits can be demonstrated and the program is introduced at a younger age. The goals of this study are to (1)establish that young athletes can tolerate the program, and (2)measure the effects of the 11+ program on the physical performance of 10-12 year old girls. Three teams will be randomly assigned to the intervention group and carry out the 11+ program for the duration of the indoor soccer season. Another 3 teams will continue with their usual warm-up. Pre- and post-intervention, balance, agility, core strength and movement control will be assessed in all athletes. The investigators hypothesize that the athletes will tolerate the program well and that the intervention group will improve on the performance tests significantly more than the control group.

Knee InjuriesAnterior Cruciate Ligament Injuries2 moreThe goal of the study is to determine effect of coach-led neuromuscular warm-up on non-contact, lower extremity (LE) injury rates among female athletes in a predominantly non-white public high school system. The investigators hypothesized the warm-up would reduce non-contact LE injuries.

Perioperative Sleep Quality and Postoperative Pain Outcomes
SurgeryACL Injury2 moreThis is a prospective, observational cohort study that will examine how sleep quality impacts postoperative pain and opioid consumption for pediatric patients. The investigators will administer a questionnaire preoperatively to determine which patients have poor or good sleep quality. They will then compare postoperative pain and opioid use between groups for two weeks following surgery. For a secondary aim, investigators will use electronic medication vials (eCAP) to monitor participants' medication use at home and compare to self-reporting.
