Elbow position alone appeared to not affect injury rates and performance in college-level, male pitchers say researchers presenting at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco, CA. "The elbow's position in relation to an injury and enhanced performance in baseball pitchers is highly dependent upon the trunk's position, " said lead researcher, Carl W. Nissen, MD of Elite Sports Medicine and Connecticut Children's Medical Center in Farmington, CT. "Our research showed that the pitching motion is complex and a direct relationship between true elbow position and how much stress is placed on a joint does not appear to exist." The researchers studied 55 collegiate-level, male pitchers who pitched a fastball towards a target 60'6" away. Kinematic data was collected using a Vicon 512 motion capture system, and kinetic data was calculated using custom Matlab programming based on inverse dynamic techniques.
Primary Anterior Cruciate Ligament (ACL) reconstruction improves quality of life and sports functionality for athletes, according to research presented at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco, CA. "ACL knee injuries have long been a source of problems for athletes, and we are excited to have such a large body of data to evaluate different treatments, " said JÃ ri T Kartus, MD, Department of Orthopaedics, NU-Hospital Organization, Sweden. "To see patients improving in the years following surgery is a great indicator of what we are doing right." The study examined data from the Swedish National ACL Reconstruction Register, which began compiling patient information in 2005. The Register consists of both patient and surgeon reported data, including the Knee Injury and Osteoarthritis Outcome (KOOS) score for quality and function after surgery, cause of injury, previous surgeries, time between injury and reconstruction, and graft type.
Despite the known success rates of reconstructive Anterior Cruciate Ligament (ACL) surgery, the number of high school and collegiate football players returning to play may not be as high as anticipated, say researchers presenting at the American Orthopaedic Society for Sports Medicine's Specialty Day in San Francisco, CA. "Previous research shows that reconstructive surgeries are a generally effective treatment for ACL injured knees. While athletes may be physically capable of playing, we sometimes ignore other factors that may prevent them from getting back out there, " said senior author Kurt P. Spindler, MD, of Vanderbilt Sports Medicine. The study examined data from patients enrolled in the Multicenter Orthopaedic Outcomes Network (MOON) cohort who underwent ACL reconstruction in 2002 and 2003.
Today in the USA, 4.5 million people are living with a total knee replacement, according to a presentation made by experts from the Orthopedic and Arthritis Center for Outcomes Research at Brigham and Women's Hospital in Boston, Mass. There are twice as many knee replacements annually now compared to ten years ago. Head researcher, Elena Losina, PhD., explained that a considerably higher number of younger patients are receiving a total knee replacement (TKR). The primary reason for TKR continues to be osteoarthritis. Losina and team gathered data from the Multicenter Osteoarthritis Study and the Osteoarthritis Initiative, the National Health Interview Survey, and the US Census data and processed the information through a computer model. They found that at least 4.5 million people in the USA today are living with one TKR or more, i.
Two studies on shoulder instability in a military population were presented by U.S. Army sports medicine surgeons at the American Academy of Orthopaedic Surgeons' annual meeting. Findings in one study suggest patients with a self-reported history of shoulder instability are far more likely to experience future instability, while the second study outlined key factors associated with surgical failure and concluded that arthroscopic surgical intervention has better outcomes than an open shoulder repair. The first study, "History of Shoulder Instability and Subsequent Injury during Four Years of Follow-up: A Survival Analysis, " prospectively followed a cohort of cadets entering the United States Military Academy over a four-year period (June 2006 through graduation in May 2010). Study authors analyzed data from 714 patients to conclude that patients with a prior history of instability were more than five times more likely to sustain an acute (anterior or posterior) instability event than those without this history.
