All the patients presented with severe generalised ligamentous laxity and aplasia of the trochlear groove. All had a lateral release, proximal \u2018tube\u2019 realignment of the patella, semitendinosus tenodesis and transfer of the patellar tendon. The mean age at the time of the operation was 6.1 years (4.9 to 6.9), and the patients were followed up for a mean of 54.5 months (31 to 66). The clinical results were evaluated using the Kujala score. <\/jats:p><jats:p> There has been no recurrence of dislocation. All the patients have returned to full activities and the parents and children were satisfied with the clinical results. The mean Kujala score was 95.3 (88 to 98). Two patients had marginal skin necrosis which healed after debridement and secondary closure. These early results in this small group have shown that the \u2018four-in-one\u2019 procedure is effective in the treatment of obligatory dislocation of the patella in children with severe ligamentous laxity and trochlear aplasia. <\/jats:p>","DOI":"10.1302\/0301-620x.89b12.19398","type":"journal-article","created":{"date-parts":[[2007,12,5]],"date-time":"2007-12-05T22:53:07Z","timestamp":1196895187000},"page":"1645-1649","source":"Crossref","is-referenced-by-count":80,"title":["The \u2018four-in-one\u2019 procedure for habitual dislocation of the patella in children"],"prefix":"10.1302","volume":"89-B","author":[{"given":"S.
