Post-acl reconstruction graft failure in severe gout arthritis patient

Introduction: Pain and instability following an anterior cruciate ligament (ACL) reconstruction remain a significant issue. Common causes include infection and inflammation, and mechanical issues such as graft failure. Case Presentation: A 36-year-old male with an ACL reconstruction six years prior was admitted due to pain and swelling. The ACL graft that had ruptured was found arthrosco-pically. Numerous gout crystals and tophus were observed inside. This finding is suggested as a cause of this kind of complication. Discussion: Biological failure is one of the causes of graft failure. Gout arthritis is associated with internal derangement of the joint structures, which is reported in advanced case. Conclusion: Severe gouty arthritis, even though rare, could be an etiology of graft failure following ACL reconstruction and cause significant morbidity.
