Abstract:
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.
Insights
Persistent pain after total knee arthroplasty can stem from various causes. This case highlights a symptomatic pseudomeniscus, successfully treated with arthroscopic debridement, offering insights into its unique fibrocartilaginous nature.
