Patient-Reported Outcomes Measurement Information System (PROMIS) scores were improved from preoperative levels at 6 months from each operation. This patient's atypical presentation of a rare disease was successfully treated with the utilization of vascularized bone grafting to salvage the tarsal navicular and preserve the talonavicular joint, enabling return of function and avoidance of early arthrodesis procedure.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.20.00010","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T12:42:57Z","timestamp":1598618577000},"page":"e20.00010-e20.00010","source":"Crossref","is-referenced-by-count":3,"title":["A Case Report of Bilateral Navicular Osteonecrosis Successfully Treated With Medial Femoral Condyle Vascularized Autografts"],"prefix":"10.2106","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0174-6544","authenticated-orcid":false,"given":"Ivan J.","family":"Zapolsky","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3535-8283","authenticated-orcid":false,"given":"Christopher R.","family":"Gajewski","sequence":"additional","affiliation":[{"name":"Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0456-7509","authenticated-orcid":false,"given":"Matthew","family":"Webb","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4497-5120","authenticated-orcid":false,"given":"Keith L.","family":"Wapner","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Pennsylvania, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9108-5182","authenticated-orcid":false,"given":"L.
