This case report describes a total knee arthroplasty (TKA) performed for the treatment of a primary knee osteoarthritis resulting from a valgus knee joint position attributed to an abnormality of the patellar ligament attachment. During a TKA, the tendon tissue in the tibial medullary canal interfered with the reamer used to prepare for the stem extensions needed to improve the fixation of the component on the tibia, which had a cortical defect. The arthroplasty succeeded, and good clinical results have been maintained over the 3\u00a0years since the surgery. Surgeons should consider careful preoperative examinations by magnetic resonance imaging or CT when an abnormal bone defect is observed at the tibial tubercle on plain X-ray images.<\/jats:p>","DOI":"10.1093\/jscr\/rjae102","type":"journal-article","created":{"date-parts":[[2024,3,7]],"date-time":"2024-03-07T09:14:46Z","timestamp":1709802886000},"source":"Crossref","is-referenced-by-count":0,"title":["Total knee arthroplasty for knee osteoarthritis associated with abnormal patellar tendon deformity: a case report"],"prefix":"10.1093","volume":"2024","author":[{"given":"Satoshi","family":"Miyamoto","sequence":"first","affiliation":[{"name":"Kohsei Chuo General Hospital Department of Orthopaedic Surgery, , 1-11-7 Mita Meguro-ku, Tokyo 153-8581, Japan"},{"name":"Tokyo Women\u2019s Medical University Yachiyo Medical Center Department of Orthopaedic Surgery, , 477-96 Owada-Shinden, Yachiyo-shi, Chiba 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shin","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Kohsei Chuo General Hospital Department of Orthopaedic Surgery, , 1-11-7 Mita Meguro-ku, Tokyo 153-8581, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Kojin","sequence":"additional","affiliation":[{"name":"University of Yamanashi Hospital Department of Clinical Quality and Medical Safety Management, , 1110 Shimokato, Chuoshi, Yamanashi 409-3898, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken","family":"Okazaki","sequence":"additional","affiliation":[{"name":"Tokyo Women\u2019s Medical University Department of Orthopaedic Surgery, , 8-1 Kawadacho, Shinjuku-ku, Tokyo 162-8666, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,3,6]]},"reference":[{"key":"2024030709143544600_ref1","first-page":"697","volume-title":"Grays Anatomy","author":"Soames","year":"1995","edition":"38th"},{"key":"2024030709143544600_ref2","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1007\/s001670000133","article-title":"The anatomy of the patellar tendon","volume":"9","author":"Basso","year":"2001","journal-title":"Knee Surg Sports Traumatol Arthrosc"},{"key":"2024030709143544600_ref3","doi-asserted-by":"crossref","first-page":"352","DOI":"10.1007\/s43465-020-00046-1","article-title":"Patellar tendon length is associated with lower extremity length but not gender","volume":"54","author":"Gloria","year":"2020","journal-title":"Indian J Orthop"},{"key":"2024030709143544600_ref4","doi-asserted-by":"crossref","first-page":"35","DOI":"10.2217\/cer-2019-0111","article-title":"The lateral and medial approach in total arthroplasty for valgus knee: a meta-analysis of current literature","volume":"9","author":"Xu","year":"2020","journal-title":"J Comp Eff Res"},{"key":"2024030709143544600_ref5","doi-asserted-by":"crossref","first-page":"81","DOI":"10.1016\/j.knee.2020.10.010","article-title":"Rotational kinematics differ between mild and severe valgus knees in total knee arthroplasty","volume":"28","author":"Kawaguchi","year":"2021","journal-title":"Knee"},{"key":"2024030709143544600_ref6","doi-asserted-by":"crossref","first-page":"e17134","DOI":"10.1097\/MD.0000000000017134","article-title":"Primary repair for injury of medial collateral ligament during total-knee arthroplasty","volume":"98","author":"Jin","year":"2019","journal-title":"Medicine"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2024\/3\/rjae102\/56876609\/rjae102.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2024\/3\/rjae102\/56876609\/rjae102.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,3,7]],"date-time":"2024-03-07T09:14:50Z","timestamp":1709802890000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjae102\/7623226"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,3]]},"references-count":6,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2024,3,5]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjae102","relation":{},"ISSN":["2042-8812"],"issn-type":[{"type":"electronic","value":"2042-8812"}],"subject":[],"published-other":{"date-parts":[[2024,3]]},"published":{"date-parts":[[2024,3]]},"article-number":"rjae102"}}
