Running mechanics, particularly knee joint kinetics and kinematics, may be impaired for years following ACLR.
Patients are typically allowed to return to running 3-5 months post-surgery, but return-to-running criteria are often poorly defined and of questionable value.
ACL injury and surgery (ACLR) results in physical and cognitive impairments which may negatively affect sports performance and contribute to increased risk of future injury, but these relationships are not well defined in elite collegiate athletes.
This study will uniquely examine a population of closely monitored, Division I, collegiate athletes and compare pre and post-ACLR quantity of sport participation and incidence of lower extremity (LE) injuries.
Laboratory-grade quantification of running mechanics are cost, time, and space-prohibitive for the majority of clinical settings, which is a barrier to utilizing new scientific knowledge to improve clinical practice.
As the availability and cost of video camera technology has improved, it may be possible to obtain meaningful information from observation of slo-motion videoanalysis.Many students coauthor journal publications and present research findings at national and state meetings.Over 480,000 young adults participate in National Collegiate Athletic Association (NCAA) sports annually.Physical therapy (PT) is a branch of medicine that seeks to help people recover from injuries and disabilities through the promotion of mobility.Physical therapy is vital in the world of sports, helping athletes recover from injury and remain able to participate in physical activity.Knee joint trauma, particularly anterior cruciate ligament (ACL) rupture and reconstruction, can contribute to quadriceps neuromuscular dysfunction that impairs rapid muscle activation and force development.Poor quadriceps function can persist for years after surgery and inhibits successful return to sport as strong and powerful quadriceps contractions are required for many athletic activities.The objectives of this ongoing investigation are to: 1) evaluate knee, hip, and ankle joint kinetics and kinematics during running and jumping in elite collegiate athletes throughout recovery post-ACLR; 2) compare and contrast the extent of kinetic and kinematic asymmetries across tasks post-ACLR; 3) compare LE movement biomechanics between post-ACLR athletes and control subjects matched by gender, sport, and position.Elite-level athletes possess a tremendous ability to perform explosive and rapid movements, developing muscular force within a short time frame.We have developed a protocol to instruct clinicians to obtain detailed and specific information from observational gait analysis to correlate with 3D obtained information and determine the magnitude of dysfunction in post-ACLR running mechanics.The goal of this investigation is to determine how accurate clinician observational gait analysis of slo motion running gait is in regards to identifying the magnitude of gait abnormalities post-ACL reconstruction.
