For active individuals, tears to the anterior cruciate ligament, which stabilizes the knee, are common. In the United States, one in 3,500 people experience this injury, according to reports. The actual incidence may be higher. Many debate whether to surgically repair a torn ACL.
New research shows that some individuals have better outcomes with rehabilitation only when compared with those who opted for surgery for a torn ACL, according to the British Journal of Sports Medicine (2022; doi:10.1136/bjsports-2022-105473).
The University of Melbourne researchers in Australia evaluated ACL healing within 5 years of an acute ACL rupture and compared surgical versus nonsurgical treatments. Investigators found that 53% of subjects who had exercise-based rehabilitation without surgery had a healed ACL within 2 years after injury. What’s important about this finding is that future ACL injury management may evolve to include support for ACL healing, rather than reconstructive surgery.
“We are now trying to understand who is most likely to experience ACL healing and whether specific treatments can increase the likelihood of ACL healing and provide a promising alternative for ACL-injured patients,” said lead study author, Stephanie Rose Filbay, PhD, senior research fellow in health, exercise, and sports medicine at The University of Melbourne.
