In this technique the femoral trochlea is deepened by removing the subchondral trochlear bone followed by incision, impaction and fixation of the cartilage flange along the trochlear groove. Between 1996 and 1999, 13 procedures were performed in 12 patients. Strictly lateral X\u2010rays showed dysplasia of the trochlea, as defined by the \u201ccrossing sign\u201d, whether or not in combination with patella alta. Patients were assessed using the Larsen\u2013Lauridsen score considering pain, stiffness, osteopatellar crepitus, flexion and loss of function. Although the majority of patients scored fair and poor on an objective scoring system, we achieved 77% good to very good subjective results. Although the result was not perfect, the patients were satisfied with the procedure. This technique might be a valuable alternative in cases of frank trochlear dysplasia associated with persistent retropatellar pain or recurrent patellar dislocations.<\/jats:p>","DOI":"10.1007\/s00167-004-0570-0","type":"journal-article","created":{"date-parts":[[2005,1,11]],"date-time":"2005-01-11T06:15:13Z","timestamp":1105424113000},"page":"529-533","source":"Crossref","is-referenced-by-count":137,"title":["Trochleoplasty in dysplastic knee trochlea"],"prefix":"10.1002","volume":"13","author":[{"given":"R.","family":"Verdonk","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery and Physical Medicine Ghent University Hospital De Pintelaan 185 9000 Gent Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Jansegers","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery and Physical Medicine Ghent University Hospital De Pintelaan 185 9000 Gent Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Stuyts","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery and Physical Medicine Ghent University Hospital De Pintelaan 185 9000 Gent Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,1,11]]},"reference":[{"issue":"76","key":"e_1_2_5_2_1","first-page":"45","article-title":"Dysplasia of the femoral trochlea","volume":"1","author":"Dejour H","year":"1990","journal-title":"Rev Chir Orthop Reparatrice Appar Mot"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01552649"},{"key":"e_1_2_5_4_1","unstructured":"GougeonF VanovermeireP MigaudH DebrouckerMJ SpiersA DuquennoyAR\u00e9sultats apr\u00e8s 3 ans de recul de 51 trochleoplasties pour instabilit\u00e9 frontale f\u00e9moropatellaire.SOFCOT 70eR\u00e9union annuelle"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.170.2.2911676"},{"key":"e_1_2_5_6_1","first-page":"5","article-title":"Apport du clich\u00e9 de profil du genou dans le d\u00e9pistage des instabilit\u00e9s rotuliennes.
