We studied the location and size of a full-thickness cartilage defect of the medial tibial plateau in 154 knees (97 patients) treated by unicompartmental (113) or total (41) knee arthroplasty between April 2017 and January 2018, and analyzed their relationship to the anterior cruciate ligament (ACL) grade, Grade 1 (normal), Grade 2 (synovial damage), Grade 3 (longitudinal split), Grade 4 (friable and fragmented), and Grade 5 (absent). Significant trends in decreased posterior preserved cartilage, increased defect length, and posteriorized defect center were associated with increasing ACL grade. Multiple comparison analysis revealed that the measurements were significantly different between ACL functional (Grades 1\u20133) and ACL deficient (Grades 4 and 5). On the other hand, the anterior preserved cartilage was consistent among the Grades. The macroscopic Oxford ACL classification system well described the disease progression where the cartilage defect extends posteriorly with ACL damage. However, 38% of ACL deficient knees had well-preserved posterior cartilage with no evident tibial anterior translation.<\/jats:p>","DOI":"10.1055\/s-0040-1721032","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T23:52:07Z","timestamp":1605138727000},"page":"884-889","source":"Crossref","is-referenced-by-count":1,"title":["Validation of the Macroscopic Anterior Cruciate Ligament Status Using the Oxford Classification System in Relation to Cartilage Defects on the Medial Tibial Plateau in Osteoarthritic Knees"],"prefix":"10.1055","volume":"35","author":[{"given":"Takafumi","family":"Hiranaka","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Joint Surgery Centre, Takatsuki General Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichi","family":"Hida","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Joint Surgery Centre, Takatsuki General Hospital, Osaka, Japan"},{"name":"Department of Orthopaedic Surgery, Kasai City Hospital, Hyogo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8846-8027","authenticated-orcid":false,"given":"Toshikazu","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Joint Surgery Centre, Takatsuki General Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenjiro","family":"Okimura","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Joint Surgery Centre, Takatsuki General Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takaaki","family":"Fujishiro","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Joint Surgery Centre, Takatsuki General Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Okamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Joint Surgery Centre, Takatsuki General Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2020,11,11]]},"reference":[{"issue":"04","key":"ref1","doi-asserted-by":"crossref","first-page":"582","DOI":"10.1302\/0301-620X.73B4.2071640","article-title":"Anteromedial osteoarthritis of the knee","volume":"73","author":"S H White","year":"1991","journal-title":"J Bone Joint Surg Br"},{"issue":"01","key":"ref2","doi-asserted-by":"crossref","first-page":"54","DOI":"10.1302\/0301-620X.88B1.17114","article-title":"The Oxford medial unicompartmental knee replacement using a minimally-invasive approach","volume":"88","author":"H Pandit","year":"2006","journal-title":"J Bone Joint Surg Br"},{"issue":"03","key":"ref3","doi-asserted-by":"crossref","first-page":"460","DOI":"10.1016\/j.knee.2016.01.018","article-title":"Accuracy of MRI evaluation of meniscus tears in the setting of ACL injuries","volume":"23","author":"F L Dufka","year":"2016","journal-title":"Knee"},{"issue":"03","key":"ref4","doi-asserted-by":"crossref","first-page":"861","DOI":"10.1148\/radiology.166.3.3340785","article-title":"Anterior cruciate ligament tears: MR imaging compared with arthroscopy and clinical tests","volume":"166","author":"J K Lee","year":"1988","journal-title":"Radiology"},{"issue":"04","key":"ref5","doi-asserted-by":"crossref","first-page":"608","DOI":"10.1302\/0301-620X.68B4.3733839","article-title":"Stress radiography in degenerative arthritis of the knee","volume":"68","author":"P H Gibson","year":"1986","journal-title":"J Bone Joint Surg Br"},{"key":"ref6","first-page":"77","volume-title":"Indications: anteromedial osteoarthritis","author":"J Goodfellow","year":"2015","edition":"2nd Ed."},{"issue":"06","key":"ref7","doi-asserted-by":"crossref","first-page":"908","DOI":"10.1002\/jor.22253","article-title":"The pattern of cartilage damage in antero-medial osteoarthritis of the knee and its relationship to the anterior cruciate ligament","volume":"31","author":"R Rout","year":"2013","journal-title":"J Orthop Res"},{"issue":"03","key":"ref8","doi-asserted-by":"crossref","first-page":"452","DOI":"10.1038\/bmt.2012.244","article-title":"Investigation of the freely available easy-to-use software \u2018EZR\u2019 for medical statistics","volume":"48","author":"Y Kanda","year":"2013","journal-title":"Bone Marrow Transplant"},{"issue":"05","key":"ref9","doi-asserted-by":"crossref","first-page":"497","DOI":"10.3109\/17453679209154722","article-title":"The radiographic classification of medial gonarthrosis.
