Is Arthroscopic Meniscectomy Associated With an Increased Risk of Total Knee Arthroplasty for Claimants in the Workers' Compensation System? A 10-Year Study of Workers' Compensation Claims From a Large Nationwide Workers' Compensation Insurance Carrier.

BACKGROUND:Total knee arthroplasty (TKA) is a commonly performed knee surgery and prior arthroscopic meniscectomy (AM) has been linked to an increased risk of TKA in the general population. OBJECTIVE:To study the relationship between AM and TKA among injured workers whose medical care is paid for under workers' compensation (WC). METHOD:A total of 17,247 lost-time claims depicting all arthroscopic knee surgical procedures performed from 2007 to 2017 were followed to the end of 2022 and analyzed. RESULTS:The odds ratio of undergoing a TKA for those with a preceding AM is 2.20, controlling for age, sex, and attorney involvement. CONCLUSIONS:Undergoing an AM is associated with an increased risk of TKA in WC claimants.
