Sports-related knee injuries in children have increased dramatically over the past decade

Knee injuries in children with tears of the anterior cruciate ligament (ACL) and meniscus have increased dramatically over the past 12 years, say orthopaedic surgeons from The Children's Hospital of Philadelphia who presented their findings today at the American Academy of Pediatrics annual meeting in Boston.

"Many people in sports medicine have assumed that these knee injuries have increased in recent years among children," said J. Todd Lawrence, M.D., Ph.D., orthopaedic surgeon at The Children's Hospital of Philadelphia and primary investigator of this study.

"Our study confirmed our hypothesis that, at least at our large academic pediatric hospital, knee injuries are an ever-growing problem for children and adolescents involved in sports." Lawrence added that people have suggested that greater participation in sports, increased clinician awareness of the signs and symptoms of ACL and meniscus tears, and advances in imaging technology may account for this increase.

The study team performed a retrospective review of records for all patients under 18 with ACL and meniscus tears treated at The Children's Hospital of Philadelphia from January 1999 through January 2011, and compared them to patients that sustained tibial spine fractures during that same time period. A total of 155 tibial spine fractures, 914 ACL tears and 996 meniscus tears were identified. Tibial spine fractures increased by only 1 per year, whereas ACL tears increased by more than 11 per year and meniscus tears increased by almost 14 per year. "Since tibial spine fractures were once thought to be the pediatric equivalent of an ACL tear," said Lawrence, "this continued rise in ACL tears in children suggests that injury patterns are changing and that the true incidence of these injuries is increasing."

Dr. Ted Ganley, one of the study's co-authors and the director of the Sports Medicine and Performance Center at Children's Hospital, noted that he hopes this research will call to light the importance of ongoing research efforts to identify pediatric and adolescent athletes who may be at risk for ACL and meniscus injuries and also encourage coaches, parents and athletes to consider incorporating injury prevention programs into their workouts. The Center has developed a sports injury prevention program called Ready, Set, Prevent which is designed to be performed on the field or the court in place of or as part of the traditional warm-up.

The Children's Hospital of Philadelphia was founded in 1855 as the nation's first pediatric hospital. Through its long-standing commitment to providing exceptional patient care, training new generations of pediatric healthcare professionals and pioneering major research initiatives, Children's Hospital has fostered many discoveries that have benefited children worldwide. Its pediatric research program is among the largest in the country, ranking third in National Institutes of Health funding. In addition, its unique family-centered care and public service programs have brought the 516-bed hospital recognition as a leading advocate for children and adolescents. For more information, visit

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
