Researchers analyzed reconstructive surgery outcomes from the largest number of patients included in a study of anterior cruciate ligament (ACL) injuries and found:
• An 82 percent increased risk for additional ACL surgery for those younger than 20.
• A 43 percent increased risk for more ACL surgery in patients aged 20 to 29.
• Females require subsequent knee surgery about 18 percent more often than males.
• Patients whose surgeons performed fewer than six ACL operations a year or who had operations in hospitals that handled fewer than 24 ACL cases a year are at higher risk for repeat surgeries.
The study’s author, Dr. Stephen Lyman, director of epidemiology and biostatics at the Hospital for Special Surgery in New York, says younger patients are likely to be at higher risk because they are more active and less likely to follow rehabilitation restrictions.
Results were published this month in The Journal of Bone and Joint Surgery.
