title: Popliteal Artery Pseudoaneurysm with Secondary Chronic Common Peroneal Nerve Neuropathy and Foot Drop after Total Knee Replacement.
abstract: Total knee replacements (TKRs) are performed to treat debilitating arthritis and are one of the most routinely performed surgical procedures in the United Kingdom. Complications of infection and deep vein thrombosis are well recognized and managed, whereas neurovascular injuries are rarely reported although should not be disregarded. We report on the case of a 72-year-old man who presented 5 weeks after a TKR with symptoms of a progressively worsening ipsilateral foot drop. A diagnosis of common peroneal nerve neuropathy secondary to the compressive effects of a popliteal pseudoaneurysm was made, and he underwent uneventful patch repair of the pseudoaneurysm. Unique to the literature is the chronicity of the foot drop, which still persisted at follow-up 6 weeks later.
