Despite a growing number of studies, numerous questions regarding patient\n\t\t\t\t\tselection remain unanswered.<\/jats:p><jats:p>\n          Patients and Methods As part of a retrospective case series with prospective follow-up (average follow-up period: 12 months), a total of 44 patients (male\/female\u2009=\u200916\/28; mean age at\n\t\t\t\t\tthe time of surgery: 55.4 years) with 44 CI were analysed (VAS, EFAS-, AOFAS-score). Using a correlation analysis and a machine learning algorithm, risk factors for therapy failure were\n\t\t\t\t\tinvestigated.<\/jats:p><jats:p>\n          Results The overall survival rate of the CI was 93% at 12 months. The VAS, EFAS and AOFAS scores showed a significant improvement in comparison to the preoperative condition. The\n\t\t\t\t\tmobility of the metatarsophalangeal joint showed no increase. Patients with a medium osteoarthritis grade and a medium level of clinical restraint showed the greatest improvement in relation\n\t\t\t\t\tto their preoperative condition.<\/jats:p><jats:p>\n          Conclusion The CI can be seen as an effective therapy for hallux rigidus. Nonetheless, realistic patient expectations must be communicated.<\/jats:p>","DOI":"10.1055\/a-1365-9655","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T23:47:47Z","timestamp":1614642467000},"page":"414-421","source":"Crossref","is-referenced-by-count":7,"title":["One-year Follow-Up Results with Hydrogel Implant in Therapy of Hallux Rigidus: Case Series with 44 Patients"],"prefix":"10.1055","volume":"160","author":[{"given":"Christoph","family":"Zanzinger","sequence":"additional","affiliation":[{"name":"Specialist Centre for Foot and Ankle Joint Surgery, Sch\u00f6n Clinic Munich-Harlaching, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norbert","family":"Harrasser","sequence":"additional","affiliation":[{"name":"Orthopaedics, Clinics Rechts der Isar of the Technical University of Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Gottschalk","sequence":"additional","affiliation":[{"name":"Specialist Centre for Foot and Ankle Joint Surgery, Sch\u00f6n Clinic Munich-Harlaching, Munich, Germany"},{"name":"Department of Gerneral, Trauma and Reconstructive Surgery, LMU Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Dolp","sequence":"additional","affiliation":[{"name":"Specialist Centre for Foot and Ankle Joint Surgery, Sch\u00f6n Clinic Munich-Harlaching, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"Hinterwimmer","sequence":"additional","affiliation":[{"name":"Orthopaedics, Clinics Rechts der Isar of the Technical University of Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hubert","family":"Hoerterer","sequence":"additional","affiliation":[{"name":"Specialist Centre for Foot and Ankle Joint Surgery, Sch\u00f6n Clinic Munich-Harlaching, Munich, Germany"},{"name":"Department of Gerneral, Trauma and Reconstructive Surgery, LMU Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Walther","sequence":"additional","affiliation":[{"name":"Specialist Centre for Foot and Ankle Joint Surgery, Sch\u00f6n Clinic Munich-Harlaching, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2021,3,1]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1136\/ard.48.4.271","article-title":"Epidemiology of osteoarthritis: Zoetermeer survey.
