Four knees showed a dislocatable patella (grade III according to Dugdale), two a dislocated reducible patella (grade IV) and four a dislocated irreducible patella (grade V). Symptoms included frequent falls, limping and pain. In all the cases a Roux\u2013Goldthwait\u2013Campbell procedure was performed. Mean age at surgery was 10 years (range 6 years and 6\u00a0months to 13 years and 4\u00a0months). Patients were reviewed at an average follow\u2010up of 8 years and 8\u00a0months (range 3 years and 6\u00a0months to 11 years and 5\u00a0months). None showed signs of recurrence of the dislocation. The median Lysholm score improved from 57.5 to 91\/100. Statistical analysis showed a significant effectiveness of the procedure in improving function, and that surgery was significantly more effective in patients with more severe disability.<\/jats:p>","DOI":"10.1007\/s00167-008-0652-5","type":"journal-article","created":{"date-parts":[[2008,10,30]],"date-time":"2008-10-30T14:58:52Z","timestamp":1225378732000},"page":"334-340","source":"Crossref","is-referenced-by-count":29,"title":["Surgical
