Patient-specific instrumentations have been introduced to improve the control of the correction. Clear evidence about customized devices for HTO and their correction accuracy lacks. Methods: The databases PUBMED and EMBASE were systematically screened for human and cadaveric studies about the use of customized devices for high tibial osteotomy and their outcomes concerning correction accuracy. Furthermore, a 3D-printed customized system for valgus HTO with three pilot cases at one-year follow-up was presented. Results: 28 studies were included. The most commonly used custom-made devices for HTO were found to be cutting guides. Reported differences between the achieved and targeted correction of hip-knee-ankle angle and the posterior tibial slope were 3\u00b0 or under. The three pilot cases that underwent personalized HTO with a new 3D-printed device presented satisfactory alignment and clinical outcomes at one-year follow-up. Conclusion: The available patient-specific devices described in the literature, including the one used in the preliminary cases of the current study, showed promising results in increasing the accuracy of correction in HTO procedure.<\/jats:p>","DOI":"10.3390\/jcm11195717","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T01:51:49Z","timestamp":1664329909000},"page":"5717","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Custom-Made Devices Represent a Promising Tool to Increase Correction Accuracy of High Tibial Osteotomy: A Systematic Review of the Literature and Presentation of Pilot Cases with a New 3D-Printed System"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2941-1407","authenticated-orcid":false,"given":"Stefano","family":"Zaffagnini","sequence":"first","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"},{"name":"Dipartimento di Scienze Biomediche e Neuromotorie (DIBINEM), University of Bologna, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8258-6425","authenticated-orcid":false,"given":"Giacomo","family":"Dal Fabbro","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4258-2267","authenticated-orcid":false,"given":"Claudio","family":"Belvedere","sequence":"additional","affiliation":[{"name":"Laboratory of Movement Analysis and Functional Evaluation of Prosthesis, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3547-7370","authenticated-orcid":false,"given":"Alberto","family":"Leardini","sequence":"additional","affiliation":[{"name":"Laboratory of Movement Analysis and Functional Evaluation of Prosthesis, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9092-225X","authenticated-orcid":false,"given":"Silvio","family":"Caravelli","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gian","family":"Lucidi","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"},{"name":"Dipartimento di Scienze Biomediche e Neuromotorie (DIBINEM), University of Bologna, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piero","family":"Agostinone","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimiliano","family":"Mosca","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Neri","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4236-1798","authenticated-orcid":false,"given":"Alberto","family":"Grassi","sequence":"additional","affiliation":[{"name":"2nd Orthopedics and Trauma Unit, IRCCS Istituto Ortopedico Rizzoli, 40136 Bologna, Italy"},{"name":"Dipartimento di Scienze Biomediche e Neuromotorie (DIBINEM), University of Bologna, 40126 Bologna, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3569","DOI":"10.1007\/s00167-020-06262-4","article-title":"Good Long-Term Survival and Patient-Reported Outcomes after High Tibial Osteotomy for Medial Compartment Osteoarthritis","volume":"29","author":"Ollivier","year":"2021","journal-title":"Knee Surg.
