ABSTRACT: Management of failed first metatarsophalangeal joint implant arthroplasty, especially in the face of infection, is an area of debate without a clear consensus. The purpose of the present report was to explore a new option of reconstructing the joint with an acellular dermal matrix substance in a single case study during a 12-month follow-up period. A staged approach that began with removal of the failed 2-component great toe implant, Koenig(®), excisional debridement of the wound with resection of the necrotic bone (proximal phalanx and distal portion of the first metatarsal bones), and culture-specific antibiosis therapy. The final stage included incorporating the acellular dermal matrix, Graftjacket(®) into the joint in an accordion-type fashion, and reconstruction of the joint capsule. Postoperative radiographs revealed a more rectus joint with some improvement in length. At 6 months postoperatively, magnetic resonance imaging revealed incorporation of the graft material into the joint. Finally, at the 1-year mark, the patient was pain free with satisfactory function at the first metatarsophalangeal joint during gait. This is the first reported case of salvaging failed and infected first metatarsophalangeal joint implant arthroplasty with incorporation of the acellular dermal matrix and provides a new option to consider in the future.
