Patellar height was measured using IS and MIS on both CR and MRI by two musculoskeletal radiologists. CMP was classified according to the International Cartilage Repair Society (ICRS) grade. Grades 1\u20132 were defined as low\u2010grade CMP, and grades 3\u20134 as high\u2010grade CMP. We analyzed the relationship between patellar height and CMP severity, as well as the inter\u2010reader and inter\u2010modality reliabilities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>High\u2010grade CMP had significantly lower IS and MIS values on both CR and MRI compared to the normal cartilage group. In patients over 50\u2009years old, the MIS value on both CR and MRI showed a significantly negative correlation with CMP grade. Inter\u2010reader reliability was excellent for both IS and MIS across CR and MRI. Inter\u2010modality reliability was excellent for IS and good for MIS. Higher IS and MIS values were observed on MRI than on CR. This is regarding the measurement results of both reviewers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>IS and MIS on both CR and MR images were reliable measures of patellar height and significantly correlated with CMP grade. In older patients, a lower MIS ratio was associated with a higher CMP grade. Although MRI tends to yield slightly higher IS and MIS values than CR, both modalities showed good agreement in measuring patellar height. These results suggest that reduced patellar height could be a relevant imaging finding in association with CMP severity.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jcu.70085","type":"journal-article","created":{"date-parts":[[2025,9,22]],"date-time":"2025-09-22T04:28:38Z","timestamp":1758515318000},"page":"391-398","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Patellar Height Measured on Radiographs and\n                    <scp>MR<\/scp>\n                    Imaging and Its Relationship With Chondromalacia Patella"],"prefix":"10.1002","volume":"54","author":[{"given":"Ji Na","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Radiology, Kangbuk Samsung Hospital Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hee Jin","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kangbuk Samsung Hospital Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeon Gyu","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kangbuk Samsung Hospital Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myung Sub","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kangbuk Samsung Hospital Sungkyunkwan University School of Medicine  Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,21]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.2729"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.asmr.2023.100855"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-009-0801-5"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-005-0015-4"},{"issue":"2","key":"e_1_2_7_6_1","first-page":"241","article-title":"A New Method of Measuring Patellar Height","volume":"59","author":"Blackburne J.
