Cannabis Use Does Not Affect Outcomes After Total Knee Arthroplasty.

Background: The self-reported use of cannabis has increased since its recent legalization in several states. The primary purpose of this study is to report total knee arthroplasty (TKA) outcomes in patients using cannabis.

Methods: Seventy-one patients who underwent a primary unilateral TKA with minimum 1-year follow-up, who self-reported cannabis use, were retrospectively reviewed.

Has Self-reported Marijuana Use Changed in Patients Undergoing Total Joint Arthroplasty After the Legalization of Marijuana?

Background: Marijuana use has become more accessible since its recent legalization in several states. However, its use in a total joint arthroplasty population to our knowledge has not been reported, and the implications of its use in this setting remain unclear.

Questions/purposes: We report (1) the self-reported use of marijuana in patients undergoing total joint arthroplasty both before and after its legalization; and (2) clinical and demographic factors associated with marijuana use in patients undergoing total joint arthroplasty.
