Filter by:The aim of this study is to investigate the influence of running to kinematic parameters of patients with anterior cruciate ligament.
The anterior cruciate ligament (ACL) is a primary stabilizer of the knee, and thus when ACL injury occurs participation in physical activity is compromised. Reconstructive surgery is often necessary to repair the damage which is then followed by a regimen of physical therapy in order to regain full activity. Nutritional intervention after the surgery could help the patient maintain muscle mass during recovery, thus allowing for a quicker return to normal activity.
The purpose of this study is to evaluate the incidence and degree of bone tunnel widening between two groups who have undergone anterior cruciate ligament reconstructive surgery. The two groups have undergone different graft fixation methods: an interference screw/suspensory button fixation hybrid technique, and an all-inside suspensory method fixation. Tunnels are created at the time of surgery for graft placement and fixation, but have been known to enlarge post-operatively. Little has been studied on the relatively new all-inside technique. X-rays of the operative knee will be used to assess tunnel width. Secondary outcomes will include clinical evaluation and outcome scoring questionnaires
There is a large number of young women who sustain serious knee injuries from playing soccer. Female athletes are at high risk of knee injuries from soccer than males. We will conduct a research project to assess the effect of a warm-up on changing some of the movement patterns thought to contribute to these serious knee injuries. It is hypothesized that a core position and control movement strategy (Core-PAC) group reduce biomechanical risk factors at the knee compared to a control after the training program.
Females 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.
