Surgery treatment, including open anatomic reduction and internal fixation, is the primary method of treatment. However, cases involving nonunion are extremely rare.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>We reported two cases in a 56\u2010year\u2010old female who visited our outpatient clinic with complaints of locking sensation, swelling, and pain, and a 64\u2010year\u2010old male patient who need additional care after having undergone surgery for a distal femur fracture. They presented with nonunion ofa Hoffa fracture (Letenneur type II), and these cases of nonunion were resolved surgically with debridement, two cannulated lag screws, a lateral extra\u2010articular buttress plate, and the liberal use of autologous bone grafts. After surgery, the two patients were allowed to bear partial weight and perform exercises. They were allowed to walk with full weight\u2010bearing after 3\u2009months. No early complications, such as infection and loss of reduction, were noted after the revision surgery. At the one\u2010year follow\u2010up, both patients had excellent function and reported minimal pain, with a Lysholm score of 94.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our case reports highlight the importance of the liberal use of autologous bone grafts, which allow stable reconstruction of the affected femoral condyle, thereby restoring joint congruence. A lateral extra\u2010articular buttress plate in combination with two cannulated lag screws is recommended for nonunion in Hoffa fracture patients, and they need to be closely followed up to detect complications promptly, especially those related to nonunion.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/os.12748","type":"journal-article","created":{"date-parts":[[2020,7,7]],"date-time":"2020-07-07T06:33:06Z","timestamp":1594103586000},"page":"1327-1331","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Surgical Treatment and Rehabilitation for Hoffa Fracture Nonunion: Two Case Reports and a Literature Review"],"prefix":"10.1111","volume":"12","author":[{"given":"Peng","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Orthopaedics Shandong Provincial Hospital affiliated to Shandong First Medical University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiu\u2010zhen","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Neurology Gaomi Hospital of Traditional Chinese Medicine  Weifang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fu\u2010lin","family":"Tao","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Shandong Provincial Hospital affiliated to Shandong First Medical University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing\u2010hu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Shandong Provincial Hospital affiliated to Shandong First Medical University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong\u2010sheng","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Shandong Provincial Hospital affiliated to Shandong First Medical University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1412-849X","authenticated-orcid":false,"given":"Fan\u2010xiao","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Shandong Provincial Hospital affiliated to Shandong First Medical University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,7,7]]},"reference":[{"key":"e_1_2_4_2_1","first-page":"213","article-title":"Hoffa's fractures.
