We studied prospectively a series of 54 consecutive patients (59 knees) with patellofemoral instability secondary to trochlear dysplasia, who were treated by a trochleoplasty by a single surgeon between June 2002 and June 2007. <\/jats:p><jats:p> Pre- and post-operative scores were assessed by the patients and a satisfaction questionnaire was completed. <\/jats:p><jats:p> Of the 54 patients (59 knees) in the series, 39 (44 knees) were female and 15 (15 knees) were male. Their mean age at surgery was 21 years and 6 months (14 years 4 months to 33 years 11 months). In 40 patients (42 knees) the mean follow-up was for 24 months (12 to 58). One patient was unable to attend for follow-up. An analysis of the results of those patients followed up for at least 12 months showed a statistically significant improvement in outcome (p &lt; 0.001 for all scores). Overall, 50 patients (92.6%) were satisfied with the outcome of their procedure. <\/jats:p><jats:p> The early results of trochleoplasty are encouraging in this challenging group of patients. <\/jats:p>","DOI":"10.1302\/0301-620x.90b2.20017","type":"journal-article","created":{"date-parts":[[2008,2,6]],"date-time":"2008-02-06T10:52:53Z","timestamp":1202295173000},"page":"180-185","source":"Crossref","is-referenced-by-count":125,"title":["A prospective evaluation of trochleoplasty for the treatment of patellofemoral dislocation and instability"],"prefix":"10.1302","volume":"90-B","author":[{"given":"M.
