An Unusual Catastrophic Neurological Complication Following a Routine Arthroscopic Multiligament Knee Reconstruction: A Case Report.

INTRODUCTION

Acute ischemic stroke following arthroscopic knee surgery is extremely rare and can result in significant morbidity and mortality. Early recognition is crucial for timely management.

CASE REPORT: A 44-year-old male with a multiligament injury of the left knee underwent arthroscopic anterior cruciate ligament reconstruction, meniscal repair, and posterior cruciate ligament avulsion fixation. In the immediate post-operative period, he developed altered sensorium and left-sided weakness. Neuroimaging revealed a massive right hemispheric infarction with complete occlusion of the right internal carotid artery. The exact etiology remained uncertain despite extensive evaluation.

CONCLUSION

Post-operative neurological deterioration following arthroscopic surgery warrants urgent evaluation. Early neurovascular imaging and multidisciplinary management are essential for the diagnosis and treatment of these rare but catastrophic events.
