Children who had delayed treatment for an Anterior Cruciate Ligament (ACL) injury have increased rates of associated knee injuries, report researchers.
"In our research, children who had delayed treatment of an ACL injury more than 150 days, tended to have an increased chance of also having a medial meniscus or chondral injury in their knee. These additional injuries may increase recovery time, inhibit return to play, and worsen long term functional outcomes of the knee," said lead researcher, Guillaume D. Dumont, MD of the University of Texas Southwestern Medical Center in Dallas, Texas. "This finding may also be relevant when counseling patients and their families regarding timing for injury treatment."
The researchers analyzed records from 370 patients who underwent ACL reconstruction between January 2005 and January 2011 at Children's Medical Center of Dallas. 200 patients were more than 15 years old and 170 patients were less than 15 years old. There were 208 male patients and 162 female patients involved in the study. Patients were injured in a variety of athletic activities: football (29.7%), basketball (20.2%), soccer (17.6%), cheerleading/gymnastics (4.3%), and other (28.1%).
The study also demonstrated a relationship of age with children more than 15 years old having a higher rate of medial femoral chondral injury. Neither gender nor sport played during injury was found to be associated with an increased rate of injury in the study.
