The incidence of ACL reconstruction (ACLR) has increased dramatically. Between 1994 and 2006, the number of these surgeries increased from an estimated 86,687 to 129,836 in the United States alone. ACL reconstructions increased most significantly among female patients and in patients under the age of 20 and those over 40.
Additionally, there has been an upward trend toward same-day and short-stay procedures. While only 43% of ACL surgeries were performed as outpatient or short-stay procedures in 1994, in 2006, 95% of ACLRs were performed in the outpatient setting.
