Pediatric Anterior Cruciate Ligament Reconstruction With Over-the-Top Femoral Position and All-Epiphyseal Tibial Tunnel

In pediatric anterior cruciate ligament reconstruction, many factors should be considered: (1) risk of growth disturbance; (2) high risk of re-tear; (3) determination of the skeletal age, which is sometimes challenging; and (4) no single technique indicated for all patients. The choice of the technique mostly depends on the patients' age and growth potential. Whereas prepubescent patients can be safely treated with physeal sparing techniques (i.e., the Kocher-Micheli technique or its modifications), in postpubescent patients physeal respecting or adult-type reconstructions are generally indicated. In pubescent patients, both all-inside all-epiphyseal and partial transphyseal techniques can be safely performed, but these are not without shortcomings. With the goal of overcoming some of the drawbacks of the existing techniques, the authors describe this technical note. The technique entails an over-the-top femoral position of a 6-strand hamstring graft and an all-epiphyseal tibial tunnel. The femoral physis is completely preserved, and only a 4.5 mm transphyseal tunnel is drilled in the tibia with an all-epiphyseal tibial half socket. With this technique, the graft diameter is adequate, there is no need for fluoroscopy, no risk of graft/tunnel mismatch, and a modified Arnold-Coker lateral tenodesis can be associated via the same lateral incision.
