A classifica tion of patellar shape was developed based on the ratio of the patellar length to the length of the articular sur face. Three classification types were established, in cluding the \"long-nosed,\" \"Cyrano\" type. Patients were placed into one of two groups based on the presence or absence of patellar pain. Lateral radiographs were evaluated for patellar height using two published indi ces. A significantly larger portion of Type II and Type III patellae was found in patients with patellar pain. More over, accepted measures of patellar height have to be used with caution in the presence of unusual patellar shapes.<\/jats:p>","DOI":"10.1177\/036354659402200111","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"61-66","source":"Crossref","is-referenced-by-count":94,"title":["Evaluation of Patellar Shape in the Sagittal Plane"],"prefix":"10.1177","volume":"22","author":[{"given":"Ronald P.","family":"Grelsamer","sequence":"first","affiliation":[{"name":"New York Orthopaedic Hospital, Division of Sports Medicine, Columbia-Presbyterian Medical Center, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S.","family":"Proctor","sequence":"additional","affiliation":[{"name":"New York Orthopaedic Hospital, Division of Sports Medicine, Columbia-Presbyterian Medical Center, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew N.","family":"Bazos","sequence":"additional","affiliation":[{"name":"New York Orthopaedic Hospital, Division of Sports Medicine, Columbia-Presbyterian Medical Center, New York, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1994,1,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"crossref","unstructured":"Blackburne JS , Peel TE A new method of measunng patellar height J Bone Joint Surg 59B 241-242, 1977","DOI":"10.1302\/0301-620X.59B2.873986"},{"key":"atypb2","doi-asserted-by":"crossref","unstructured":"Carman DL, Browne RH, Birch JG Measurement of scoliosis and kyphosis radiographs Intraobserver and interobserver variation.
