Furthermore, we propose\n\t\t\t\t\ta treatment algorithm based on two pillars: our case series of nine patients presenting medial Hoffa fractures and the best evidence-based pertinent literature. Fracture healing, range of\n\t\t\t\t\tmotion, function, and complications were evaluated after a minimum of 6 months follow-up.<\/jats:p><jats:p>\n          Results All fractures healed with no loss of reduction. Knee flexion ranged from 90\u200a\u2013\u200a130\u00b0 (mean 110\u00b0, standard deviation 15.2). Knee extension ranged from 0\u200a\u2013\u200a10\u00b0 (mean 1\u00b0, standard\n\t\t\t\t\tdeviation 3.3). Knee function according to the Lysholm score ranged from 74\u200a\u2013\u200a96 points (mean 85, standard deviation 6.3). There were no complications such as infection, fixation failure, or\n\t\t\t\t\tmedial femoral condyle osteonecrosis. One patient required hardware removal due to soft tissue irritation and one patient underwent knee mobilization under anesthesia after 8 weeks of\n\t\t\t\t\tfracture fixation due to knee stiffness.<\/jats:p><jats:p>\n          Conclusion The presented rationale for treatment based on the new classification system is a simple and effective strategy on the decision-making process for adequate management of\n\t\t\t\t\tmedial Hoffa fractures.<\/jats:p>","DOI":"10.1055\/a-1289-1102","type":"journal-article","created":{"date-parts":[[2020,12,9]],"date-time":"2020-12-09T23:49:26Z","timestamp":1607557766000},"page":"269-277","source":"Crossref","is-referenced-by-count":11,"title":["Medial Hoffa Fracture: Description of a Novel Classification System and Rationale for Treatment Based on Fragment-Specific Fixation Strategy"],"prefix":"10.1055","volume":"160","author":[{"given":"Robinson Esteves","family":"Pires","sequence":"additional","affiliation":[{"name":"Departamento do Aparelho Locomotor, Universidade Federal de Minas Gerais, Belo Horizonte, Brazil"},{"name":"Servi\u00e7o de Ortopedia e Traumatologia, Instituto Orizonti, Belo Horizonte, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Bidolegui","sequence":"additional","affiliation":[{"name":"Servicio de Ortopedia y Traumatolog\u00eda, Hospital Sirio-Liban\u00e9s, Buenos Aires, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebasti\u00e1n","family":"Pereira","sequence":"additional","affiliation":[{"name":"Servicio de Ortopedia y Traumatolog\u00eda, Hospital Sirio-Liban\u00e9s, Buenos Aires, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincenzo","family":"Giordano","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Ortopedia e Traumatologia Prof. Nova Monteiro, Hospital Municipal Miguel Couto, Rio de Janeiro, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcos","family":"Giordano","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Ortopedia e Traumatologia, Hospital de For\u00e7a A\u00e9rea do Gale\u00e3o, Rio de Janeiro, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steffen","family":"Schr\u00f6ter","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Reconstructive Surgery, Diakonie Klinikum GmbH Jung-Stilling, Siegen, Siegen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2020,12,9]]},"reference":[{"key":"ref1","first-page":"132","article-title":"Unicondylar femoral fractures: therapeutic strategy and long-term results.
