Post-operatively, patellofemoral pain, present pre-operatively in only 35 knees, became worse in 15 (33.4%), remained unchanged in four (8.8%) and improved in 22 (49%). Four knees which had no pain pre-operatively (8.8%) continued to have no pain. <\/jats:p><jats:p> A total of 33 knees were available for radiological assessment. Post-operatively, all but two knees (93.9%) had correction of trochlear dysplasia radiologically but degenerative changes of the patellofemoral joint developed in 30% (10) of the knees. <\/jats:p><jats:p> We conclude that recurrent patellar dislocation associated with trochlear dysplasia can be treated successfully by trochleaplasty, but the impact on patellofemoral pain and the development of patellofemoral osteoarthritis is less predictable. Overall, subjective patient satisfaction with restored patellofemoral stability after trochleaplasty appeared to outweigh its possible sequelae. <\/jats:p>","DOI":"10.1302\/0301-620x.88b10.17834","type":"journal-article","created":{"date-parts":[[2006,9,29]],"date-time":"2006-09-29T16:53:40Z","timestamp":1159548820000},"page":"1331-1335","source":"Crossref","is-referenced-by-count":240,"title":["Trochleaplasty for recurrent patellar dislocation in association with trochlear dysplasia"],"prefix":"10.1302","volume":"88-B","author":[{"given":"F.","family":"von Knoch","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Schulthess Clinic, Lengghalde 2, 8008 Zurich, Switzerland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"B\u00f6hm","sequence":"additional","affiliation":[{"name":"Department of Radiology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
