The age of the patients varied from newborn to 38 years. A total of 18 patients was followed during their growth until adolescence. The knees of two legally aborted fetuses appeared on examination to be macroscopically normal and congruous. Excessive valgus deformity of the tibiofemoral weight-bearing angle with a mean of 14\u00b0 was noted in infancy. Most of the patients had marked instability of the knees. The range of movement of the knee began to decrease before the age of five years. There were signs of early degeneration and deformation of the bony epiphyses before the age of six years. The patellofemoral joint was abnormal from an early age. A marked patella infera, often associated with a lateral position of the patella with bony fragmentation, was noted. The knee in diastrophic dysplasia is basically unstable, showing early deformation of the subchondral bone and degeneration of the joint.<\/jats:p>","DOI":"10.1302\/0301-620x.81b4.0810625","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T06:51:05Z","timestamp":1519195865000},"page":"625-631","source":"Crossref","is-referenced-by-count":22,"title":["The knee joint in diastrophic dysplasia"],"prefix":"10.1302","volume":"81-B","author":[{"given":"J.","family":"Peltonen","sequence":"first","affiliation":[{"name":"Hospital for Children and Adolescents, University of Helsinki, Stenb\u00e4ck-inkatu 11, SF-00290 Helsinki, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Vaara","sequence":"additional","affiliation":[{"name":"Hospital for Children and Adolescents, University of Helsinki, Stenb\u00e4ck-inkatu 11, SF-00290 Helsinki, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Marttinen","sequence":"additional","affiliation":[{"name":"Hospital for Children and Adolescents, University of Helsinki, Stenb\u00e4ck-inkatu 11, SF-00290 Helsinki, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Ry\u00f6ppy","sequence":"additional","affiliation":[{"name":"Hospital for Children and Adolescents, University of Helsinki, Stenb\u00e4ck-inkatu 11, SF-00290 Helsinki, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Poussa","sequence":"additional","affiliation":[{"name":"Orton Hospital, Invalid Foundation, Tenholantie 10, SF-00280 Helsinki, Finland."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","container-title":["The Journal of Bone and Joint Surgery.
