Management of Periprosthetic Polyvinyl Alcohol Synthetic Cartilage Implant Infection with Staged First Metatarsophalangeal Joint Arthrodesis.

Surgical management of hallux rigidus using a polyvinyl alcohol synthetic cartilage implant has gained popularity among foot and ankle surgeons. Although uncommon, appropriate diagnosis and management of a periprosthetic implant infection is critical in limiting morbidity. We present a case report and staged technique for converting a first metatarsal synthetic cartilage hemiarthroplasty to arthrodesis in the setting of a periprosthetic joint infection.
