Overlooked Hormone May Indicate Female Athletes At Risk For Knee Injury

Says a latest Stanford University study performed by the Department of Orthopedic Surgery1.

The female anterior cruciate ligament may be more susceptible to injury than the male anterior cruciate ligament because of the gender-specific expression of receptors for relaxin, a collagenolytic hormone that promotes remodeling of the anterior cruciate ligament.

Division I female athletes participating in sports with a high incidence of anterior cruciate ligament tears (basketball, lacrosse, field hockey, soccer, gymnastics, and volleyball) participated in the 5-year study.

A surprising positive correlation was found – those athletes with elevated serum relaxin concentrations (SRC) experienced ACL tears at a higher rate than those with lower levels. In fact, those athletes who experienced an ACL tear averaged double the SRC concentration as those with no tear.

One more alarming fact:

Those with an SRC greater than 6.0 pg/mL had over 4 times increased risk for a tear

Downers Grove physical therapy programs have solutions for those female athletes facing an ACL injury. Comprehensive pre & post surgery rehabilitation is available utilizing cutting-edge techniques to ensure a healthy and rapid recovery, with a dedicated mission in returning athletes to normal function and sporting activities.
