Persistent pain following total knee arthroplasty is an uncommon complication that may have any of several causes. In the case reported here, a patient who had undergone total knee arthroplasty developed a symptomatic pseudomeniscus that was successfully treated by arthroscopic debridement. Histopathologic analysis of the pseudomeniscus revealed a unique fibrocartilaginous structure, which may give insight into its pathogenesis. Symptomatic pseudomeniscus is one of several postoperative complications of total knee arthroplasty for which arthroscopy may be indicated.
