Three cases of long\u2010standing uncorrected flexion contractures of the knees are presented that resulted in marked erosion of the femoral trochlea, patella baja, and remodeled patellar articular surfaces likely reflecting increased angles of flexion. It is probable that the deep femoral grooves are the result of adaptation under high\u2010level persistent contact loads from the quadriceps tendon. These examples expand our knowledge of bone remodeling and offer information of potential use in studying ancient skeletal samples.<\/jats:p>","DOI":"10.1002\/ajpa.1330850311","type":"journal-article","created":{"date-parts":[[2006,2,3]],"date-time":"2006-02-03T20:24:51Z","timestamp":1138998291000},"page":"321-327","source":"Crossref","is-referenced-by-count":5,"title":["Pressure erosion of the femoral trochlea, patella baja, and altered patellar surfaces"],"prefix":"10.1002","volume":"85","author":[{"given":"Robert W.","family":"Mann","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charlotte A.","family":"Roberts","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael D.","family":"Thomas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dwight T.","family":"Davy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,5,2]]},"reference":[{"key":"e_1_2_1_2_1","volume-title":"Paleopathology of Danish skeletons: A Comparative Study of Demography, Disease and Injury","author":"Bennike P","year":"1985"},{"key":"e_1_2_1_3_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1097\/00003086-198808000-00003","article-title":"Spasticity and contracture: Physiologic aspects of formation","volume":"233","author":"Botte MJ","year":"1988","journal-title":"Clin.
