RESUMEN
With the heightened popularity of childhood sporting activity, the number of paediatric anterior cruciate ligament (ACL) ruptures has increased. Management of these injuries presents a particular challenge due to the open femoral and tibial growth plates. Physeal damage has the potential to cause angular deformity or length discrepancy. This review was conducted to determine the best way to treat this injury. A primary search of Ovid MEDLINE (1 October 2017) used the terms: (ACL or anterior cruciate ligament) and (young or child or children or pediatric or immature or pre-pubescent). Titles/Abstracts of 369 articles were screened for relevance. A total of 217 were excluded, leaving 152 articles for full-paper retrieval. Of these, 9 articles remained with one further article identified during cross-referencing; 10 papers (1 level 2 and 9 level 3) were included for analysis. Comparative studies investigating surgical (140 knees) versus conservative (110 knees) treatment provide evidence in favour of the former, in reducing instability and meniscal tears and improving return to previous activity. Of the papers analysed (163 reconstructions), there was only one case of growth arrest (0.6%) and no cases of length discrepancy. In those studies investigating early (218 patients) versus delayed (140 patients) reconstruction, medial meniscal tears and chondral injuries occurred more frequently in the delayed group. To conclude, for children, there is level 2/3 evidence that early operative ACL reconstruction offers the best chance of a return to pre-injury sporting activity and minimises the risks of further structural damage. Iatrogenic growth disturbance remains a rare but worrying complication.
