Mean AOFAS score was 72 \u00b1 19 points and Foot Function Index was 27 \u00b1 26 points (all 31 feet). Clinical rating for 29 feet that had surgery as a primary procedure was excellent in 5 feet (17%), good in 8 feet (28%), fair in 3 feet (10%), and poor in 13 feet (45%). Patients were satisfied with the outcome in 24 feet (77%). Follow-up radiographs showed that radiolucency, change in angulation, sinkage, and malalignment of the metatarsal or proximal phalanx components were common. Complications included 1 superficial wound infection, and revision was performed in 5 feet (16%) because of loosening, sinkage, subluxation, pain, or fractured prosthesis. Implant survival was 92% at 5 years, 85% at 7 years, and 68% at 9 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The results of second-generation ceramic first MP joint replacement in our series demonstrated poor clinical and radiological results with a high revision rate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>Level IV, case series.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1071100714536539","type":"journal-article","created":{"date-parts":[[2014,7,2]],"date-time":"2014-07-02T04:39:00Z","timestamp":1404275940000},"page":"690-698","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":26,"title":["Second-Generation Ceramic First Metatarsophalangeal Joint Replacement for Hallux Rigidus"],"prefix":"10.1177","volume":"35","author":[{"given":"Mathias Thomas","family":"Nagy","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, Foot and Ankle Unit, Royal Liverpool and Broadgreen University Hospitals, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher Richard","family":"Walker","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, Foot and Ankle Unit, Royal Liverpool and Broadgreen University Hospitals, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siva Prasad","family":"Sirikonda","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, Foot and Ankle Unit, Royal Liverpool and Broadgreen University Hospitals, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2014,7,1]]},"reference":[{"key":"bibr1-1071100714536539","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800310"},{"key":"bibr2-1071100714536539","doi-asserted-by":"crossref","unstructured":"Arbuthnot JE, Cheung G, Balain B, Replacement arthroplasty of the first metatarsophalangeal joint using a ceramic-coated endoprosthesis for the treatment of hallux rigidus.
